我有一个.resx文件，其中包含名称 - 值对（两个字符串）。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。
http://msdn.microsoft.com/en-us/library/system.resources.aspx
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();
}

如果你想保留资源文件中的现有注释，那么使用它（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)
{

using (var reader = new ResXResourceReader(resourceFilepath))

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());

Womp说得对（10x）。
但这是一个保持XML文件顺序的代码，在文件末尾添加new。 （用于源代码管理）
//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＆＃39;并基于SirMoreno的代码。只是短一点。对于我来说，这仍然不是一个可能但不是必需的元数据。
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<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();
}

所有其他答案都使用了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，也是更好的。
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：
<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>
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。
