Modification du fichier .resx en C #
J'ai un fichier .resx qui contient des paires nom-valeur (les deux chaînes). Maintenant, je veux modifier les valeurs dans certaines paires nom-valeur par programme en utilisant C #. Comment puis-je y arriver?
Il existe un espace de noms complet pour la gestion des ressources: System.Resources. Découvrez la classe ResourceManager, ainsi que ResXResourceReader et ResXResourceWriter.

J'ai réussi à mettre la main sur une très ancienne méthode de débogage que j'avais l'habitude d'utiliser à un moment donné lorsque je testais des éléments liés aux ressources. Cela devrait faire l'affaire pour vous.
public static void UpdateResourceFile(Hashtable data, String path)
{
Hashtable resourceEntries = new Hashtable();
//Get existing resources
ResXResourceReader reader = new ResXResourceReader(path);
if (reader != null)
{
IDictionaryEnumerator id = reader.GetEnumerator();
foreach (DictionaryEntry d in reader)
{
if (d.Value == null)
resourceEntries.Add(d.Key.ToString(), "");
else
resourceEntries.Add(d.Key.ToString(), d.Value.ToString());
}
reader.Close();
}
//Modify resources here...
foreach (String key in data.Keys)
{
if (!resourceEntries.ContainsKey(key))
{
String value = data[key].ToString();
if (value == null) value = "";
resourceEntries.Add(key, value);
}
}
//Write the combined resource file
ResXResourceWriter resourceWriter = new ResXResourceWriter(path);
foreach (String key in resourceEntries.Keys)
{
resourceWriter.AddResource(key, resourceEntries[key]);
}
resourceWriter.Generate();
resourceWriter.Close();
}
Si vous souhaitez conserver les commentaires existants dans les fichiers de ressources, utilisez ceci (Selon le code de SirMoreno modifié)
public static void UpdateResourceFile(Hashtable data, String path)
{
Hashtable resourceEntries = new Hashtable();
//Get existing resources
ResXResourceReader reader = new ResXResourceReader(path);
reader.UseResXDataNodes = true;
ResXResourceWriter resourceWriter = new ResXResourceWriter(path);
System.ComponentModel.Design.ITypeResolutionService typeres = null;
if (reader != null)
{
IDictionaryEnumerator id = reader.GetEnumerator();
foreach (DictionaryEntry d in reader)
{
//Read from file:
string val = "";
if (d.Value == null)
resourceEntries.Add(d.Key.ToString(), "");
else
{
val = ((ResXDataNode)d.Value).GetValue(typeres).ToString();
resourceEntries.Add(d.Key.ToString(), val);
}
//Write (with read to keep xml file order)
ResXDataNode dataNode = (ResXDataNode)d.Value;
//resourceWriter.AddResource(d.Key.ToString(), val);
resourceWriter.AddResource(dataNode);
}
reader.Close();
}
//Add new data (at the end of the file):
Hashtable newRes = new Hashtable();
foreach (String key in data.Keys)
{
if (!resourceEntries.ContainsKey(key))
{
String value = data[key].ToString();
if (value == null) value = "";
resourceWriter.AddResource(key, value);
}
}
//Write to file
resourceWriter.Generate();
resourceWriter.Close();
}
public static void AddOrUpdateResource(string key, string value)
{
var resx = new List<DictionaryEntry>();
using (var reader = new ResXResourceReader(resourceFilepath))
{
resx = reader.Cast<DictionaryEntry>().ToList();
var existingResource = resx.Where(r => r.Key.ToString() == key).FirstOrDefault();
if (existingResource.Key == null && existingResource.Value == null) // NEW!
{
resx.Add(new DictionaryEntry() { Key = key, Value = value });
}
else // MODIFIED RESOURCE!
{
var modifiedResx = new DictionaryEntry()
{ Key = existingResource.Key, Value = value };
resx.Remove(existingResource); // REMOVING RESOURCE!
resx.Add(modifiedResx); // AND THEN ADDING RESOURCE!
}
}
using (var writer = new ResXResourceWriter(ResxPathEn))
{
resx.ForEach(r =>
{
// Again Adding all resource to generate with final items
writer.AddResource(r.Key.ToString(), r.Value.ToString());
});
writer.Generate();
}
}
Womp l'a bien compris (10x).
Mais voici un code qui conserve l'ordre des fichiers XML, ajoutez-en un nouveau à la fin du fichier. (pour le contrôle de source)
//Need dll System.Windows.Forms
public static void UpdateResourceFile(Hashtable data, String path)
{
Hashtable resourceEntries = new Hashtable();
//Get existing resources
ResXResourceReader reader = new ResXResourceReader(path);
ResXResourceWriter resourceWriter = new ResXResourceWriter(path);
if (reader != null)
{
IDictionaryEnumerator id = reader.GetEnumerator();
foreach (DictionaryEntry d in reader)
{
//Read from file:
string val = "";
if (d.Value == null)
resourceEntries.Add(d.Key.ToString(), "");
else
{
resourceEntries.Add(d.Key.ToString(), d.Value.ToString());
val = d.Value.ToString();
}
//Write (with read to keep xml file order)
resourceWriter.AddResource(d.Key.ToString(), val);
}
reader.Close();
}
//Add new data (at the end of the file):
Hashtable newRes = new Hashtable();
foreach (String key in data.Keys)
{
if (!resourceEntries.ContainsKey(key))
{
String value = data[key].ToString();
if (value == null) value = "";
resourceWriter.AddResource(key, value);
}
}
//Write to file
resourceWriter.Generate();
resourceWriter.Close();
}
Toutes les autres réponses utilisent ResXResourceWriter, mais dans certains cas particuliers, il peut être faisable et préférable de travailler simplement avec le fichier Resources.resx en tant que document XML.
J'ai une situation spécifique où je veux manipuler les entrées de Resources.resx pour un ensemble de fichiers d'icônes. Il peut y avoir plusieurs centaines d'entrées, et je peux compter sur elles qui ressemblent toutes exactement à ceci:
<data name="Incors_workplace2_16x16" type="System.Resources.ResXFileRef, System.Windows.Forms">
<value>..\..\..\..\..\..\Icons\Incors-workplace2-16x16.png;System.Drawing.Bitmap, System.Drawing, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a</value>
</data>
J'ai essayé d'utiliser ResXResourceWriter et ResXResourceReader pour ce programme, mais j'ai fini par ouvrir les différents fichiers Resources.resx sous forme de documents XML et de les manipuler de cette façon. Le programme dans son ensemble est beaucoup trop volumineux (et trop spécifique à une application) pour être publié ici, mais je vais publier quelques fragments de code pour montrer certaines des techniques pouvant être utilisées.

Ceci est ma version basée sur Ers et sur le code de SirMoreno. Juste un peu plus court. Ce n'est toujours pas manipuler metaData, ce qui est possible mais pas nécessaire pour moi.
public static bool AddToResourceFile(string key, string value, string comment, string path)
{
using (ResXResourceWriter resourceWriter = new ResXResourceWriter(path))
{
//Get existing resources
using (ResXResourceReader reader = new ResXResourceReader(path) { UseResXDataNodes = true })
{
foreach (DictionaryEntry resEntry in reader)
{
ResXDataNode node = resEntry.Value as ResXDataNode;
if (node == null) continue;
if (string.CompareOrdinal(key, node.Name) == 0)
{
// Keep resources untouched. Alternativly modify this resource.
return false;
}
resourceWriter.AddResource(node);
}
}
//Add new data (at the end of the file):
resourceWriter.AddResource(new ResXDataNode(key, value) { Comment = comment });
//Write to file
resourceWriter.Generate();
}
return true;
}
La réponse de Womp est améliorée - sans Hashtable obsolète, vérifier si le fichier existe et utiliser LINQ:
public static void UpdateResourceFile(Dictionary<string, string> data, string path)
{
Dictionary<string, string> resourceEntries = new Dictionary<string, string>();
if (File.Exists(path))
{
//Get existing resources
ResXResourceReader reader = new ResXResourceReader(path);
resourceEntries = reader.Cast<DictionaryEntry>().ToDictionary(d => d.Key.ToString(), d => d.Value?.ToString() ?? "");
reader.Close();
}
//Modify resources here...
foreach (KeyValuePair<string, string> entry in data)
{
if (!resourceEntries.ContainsKey(entry.Key))
{
if (!resourceEntries.ContainsValue(entry.Value))
{
resourceEntries.Add(entry.Key, entry.Value);
}
}
}
string directoryPath = Path.GetDirectoryName(path);
if (!string.IsNullOrEmpty(directoryPath))
{
Directory.CreateDirectory(directoryPath);
}
//Write the combined resource file
ResXResourceWriter resourceWriter = new ResXResourceWriter(path);
foreach (KeyValuePair<string, string> entry in resourceEntries)
{
resourceWriter.AddResource(entry.Key, resourceEntries[entry.Key]);
}
resourceWriter.Generate();
resourceWriter.Close();
}
