我对于静态 System.IO.File 和目录方法的已写入适配器。然后在我的课程中，我执行以下操作：

I've written adapters for the static System.IO.File and Directory methods. Then in my classes I do the following:

public class MyService {
  public IFile File {private get;set;}
  public MyService() {
    File = new FileImpl();
  }
  public void DoSomething() {
    File.ReadAllText("somefile");
  }
}

然后，您可以将模拟注入为IFile进行测试。

Then you can inject a mock as IFile for testing.
