解决此问题所需要做的就是右键单击解决方案资源管理器中的Resources.resx文件，然后单击运行自定义工具.重新生成自动生成的Resources.Designer.cs文件.

All I needed to do to fix this problem was to right-click the Resources.resx file in the Solution Explorer and click Run Custom Tool. This re-generates the auto-generated Resources.Designer.cs file.

如果.resx文件是手动添加到项目中的，则该文件的自定义工具"属性必须设置为"ResXFileCodeGenerator".

If the .resx file was added to the project manually, the Custom Tool property of the file must be set to "ResXFileCodeGenerator".

问题是由于名称空间不匹配引起的，如果您在项目设置中更改了程序集的默认名称空间"，则会发生此问题. (我将其从(以前)"Servers"更改为(现在)"RT.Servers".)

The problem is due to a mismatch of namespaces, which occurs if you change the "default namespace" of the assembly in the project settings. (I changed it from (previously) "Servers" to (now) "RT.Servers".)

在Resources.Designer.cs中自动生成的代码中，有以下代码:

In the auto-generated code in Resources.Designer.cs, there is the following code:

internal static global::System.Resources.ResourceManager ResourceManager {
    get {
        if (object.ReferenceEquals(resourceMan, null)) {
            global::System.Resources.ResourceManager temp = new global::System.Resources.ResourceManager("Servers.Resources", typeof(Resources).Assembly);
            resourceMan = temp;
        }
        return resourceMan;
    }
}

文字字符串"Servers.Resources"必须更改为"RT.Servers.Resources".我是手动完成的，但是运行自定义工具也可以做到.

The literal string "Servers.Resources" had to be changed to "RT.Servers.Resources". I did this manually, but running the custom tool would have equally well done it.
