Thanks For Your Help..
推荐答案
Visual Studio添加行：
Visual studio adds the line:
throw new NotImplementedException();当它自动为您创建一个方法时，允许您有一个标记，表明您需要做一些工作。如果你忘记了，那么当你运行你的代码时会抛出异常，这会警告你的代码可能不起作用 - 因为你没有写过它！
删除该行，并填写代码以执行该方法的功能！
When it automatically creates a method for you, allowing you to have a marker that there is some work you have to do. If you forget, then the exception is thrown when you run your code, and this serves as a warning that your code probably won't work - because you haven't written it!
Remove the line, and fill in the code to perform the function the method is there for!
