推荐答案

在button1_click事件中，当你调用setdatasource方法时，该方法会抛出一个notimplementedexception，这就是为什么你得到那个异常 In button1_click event when you call setdatasource method the method throws a notimplementedexception thats why ur getting that exception

尝试在方法中的SetDataSource（）中添加代码而不是抛出新的 trying adding code in SetDataSource() in the method instead of throw new
