J'ai eu un fichier .resx contenant des paires de valeurs de nom de chaîne. Maintenant, je veux modifier les valeurs dans certaines paires de valeurs de nom par programmation en utilisant C#. Comment puis-je y parvenir?Modification du fichier .resx dans C#

Merci d'avance.

Je serais curieux d'entendre le (s) cas d'utilisation pour cela. J'ai un client qui voudrait modifier les ressources à la volée, mais tout à ce propos semble contre nature et contraire aux objectifs des fichiers de ressources. – MrBoJangles

Il existe tout un espace de noms pour la gestion des ressources: System.Resources. Extrayez la classe ResourceManager, ainsi que ResXResourceReader et ResXResourceWriter.

http://msdn.microsoft.com/en-us/library/system.resources.aspx


j'ai réussi à mettre la main sur une méthode de débogage très vieux que je l'habitude d'utiliser à un moment donné quand je testais des trucs 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(); 

    }

Est-ce la seule façon de mettre à jour un kvp dans un fichier resx? Il semble que ce serait juste ajouter un autre kvp au fichier. – dotnetN00b

Womp a bien compris (10x).

Mais voici un code qui conserve l'ordre du fichier XML, ajouter nouveau à la fin du fichier. (pour le contrôle de la 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(); 

    }

C'est ma version à base sur Ers et basé sur le code de SirMoreno. Juste un peu plus court. Ce n'est toujours pas manipuler les méta-données 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;

C'est amélioré la réponse de Womp - sans Hashtable obsolète, vérifier si le fichier existe et 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(); 
    }

Toutes les autres réponses font usage de ResXResourceWriter, mais pour certains cas particuliers, il peut être faisable et mieux de simplement travailler avec le fichier Resources.resx en tant que document XML.

J'ai une situation spécifique où je veux manipuler les entrées Resources.resx pour un ensemble de fichiers d'icônes. Il peut y avoir jusqu'à plusieurs centaines d'entrées, et je peux compter sur eux tous à la recherche exactement comme 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 je fini par ouvrir à la place les différents fichiers Resources.resx comme des documents XML et les manipuler de cette manière. L'ensemble du programme est beaucoup trop volumineux (et trop spécifique aux applications) pour être publié ici, mais je vais poster quelques souches de code pour montrer certaines des techniques qui peuvent être utilisées.

 /// <summary> 
     /// Method to load a Resources.resx file (if it exists) as an XML Document object. 
     /// </summary>

     string fileName = projectPath + @"Properties\Resources.resx"; 
     if (!File.Exists(fileName)) 
      return null; 

     XmlDocument xdResx = new XmlDocument(); 
     xdResx.Load(fileName);

     // Loop for all of the <data> elements that have name= attributes (node = "name" attr.) 
     XmlNodeList xnlDataElements = xdResx.SelectNodes("/root/data/@name"); 
     if (xnlDataElements != null) 
     { 
      foreach (XmlNode xmlNode in xnlDataElements) 
      { 
       // Modify the name= attribute if necessary
