在C＃中修改.resx文件
我有一个包含名称 – 值对（两个字符串）的.resx文件。 现在我想使用C＃以编程方式修改某些名称 – 值对中的值。 我怎样才能做到这一点？
资源管理有一个完整的命名空间：System.Resources。 查看ResourceManager类，以及ResXResourceReader和ResXResourceWriter。

我设法把手放在一个非常古老的调试方法上，当我测试一些资源相关的东西时，我曾经使用过这种方法。 这应该是你的伎俩。
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(); }
如果要保留资源文件中的现有注释，请使用此（基于SirMoreno的代码修改）
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(); using (var reader = new ResXResourceReader(resourceFilepath)) { resx = reader.Cast ().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做对了（10x）。
但这是一个保持XML文件顺序的代码，在文件末尾添加new。 （用于源控制）
//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(); }
这是我的版本基于Ers’并基于SirMoreno的代码。 只是短一点。 这仍然不是对metaData的处理，这对我来说是可能的但不是必需的。
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; }
这是改进Womp的答案 – 没有过时的Hashtable，检查文件是否存在并使用LINQ：
public static void UpdateResourceFile(Dictionary data, string path) { Dictionary resourceEntries = new Dictionary(); if (File.Exists(path)) { //Get existing resources ResXResourceReader reader = new ResXResourceReader(path); resourceEntries = reader.Cast().ToDictionary(d => d.Key.ToString(), d => d.Value?.ToString() ?? ""); reader.Close(); } //Modify resources here... foreach (KeyValuePair 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 entry in resourceEntries) { resourceWriter.AddResource(entry.Key, resourceEntries[entry.Key]); } resourceWriter.Generate(); resourceWriter.Close(); }
所有其他答案都使用ResXResourceWriter，但对于某些特殊情况，简单地将Resources.resx文件作为XML文档使用可能是可行的。
我有一个特定的情况，我想操作一组图标文件的Resources.resx条目。 可能有多达几百个条目，我可以指望它们看起来完全像这样：
..\..\..\..\..\..\Icons\Incors-workplace2-16x16.png;System.Drawing.Bitmap, System.Drawing, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
我尝试将ResXResourceWriter和ResXResourceReader用于此程序，但最终我将各种Resources.resx文件作为XML文档打开并以这种方式操作它们。 整个程序太大了（也是特定于应用程序）在这里发布，但我会发布一些代码来展示一些可以使用的技术。
