winform中devexpress bindcommand無效的解決方法

正常綁定，編譯運行無報錯，但沒法執行command

fluentAPI.BindCommand(commandButton, (x, p) => x.DoSomething(p), x => parameter);

解決方法：
檢查command訪問權限，在devexpress規範中，command必須爲 public void
提示信息：All public void methods with zero or one parameter, declared in POCO ViewModels, are treated as commands.
在view層寫綁定的時候，經過alt+enter自動生成的command是Internal修飾的（程序集訪問權限），沒法訪問。

    internal  void DoSomething(int p) {//將  internal改成public
        XtraMessageBox.Show(string.Format(
            "Hello! The parameter passed to command is {0}." + Environment.NewLine +
            "And I'm running, because the `canExecute` condition is `True` for this parameter." + Environment.NewLine +
            "Try to change this parameter!", p));
    }
