如何解决“编译器错误 - 无法从方法组转换成System.Delegate'？ [英] How do I fix 'compiler error - cannot convert from method group to System.Delegate'?

问题描述

 public MainWindow()
 {
    CommandManager.AddExecutedHandler(this, ExecuteHandler);
 }

 void ExecuteHandler(object sender, ExecutedRoutedEventArgs e)
 {
 }

错误1参数2：无法从方法组转换为System.Delegate

Error 1 Argument 2: cannot convert from 'method group' to 'System.Delegate'

推荐答案

我想有不同的签名的多个ExecuteHandler。只投​​你的处理器的版本，你想有：

I guess there are multiple ExecuteHandler with different signatures. Just cast your handler to the version you want to have:

CommandManager.AddExecuteHandler(this, (Action<object,ExecutedRoutedEventArgs>)ExecuteHandler);
