WPF里关于继承基类

[huangheping520hhp]

namespace TwoToOnePokerGame
{
/// <summary>
/// Interaction logic for frmWinGame.xaml
/// </summary>
public partial class FormWinGame: DialogWindowBase
{
public FormWinGame()
{
InitializeComponent();
}

private void button1_Click(object sender, RoutedEventArgs e)
{
((MainForm)ParentWindow).StartNewGame();
this.Close();
}

private void button2_Click(object sender, RoutedEventArgs e)
{
Application.Current.Shutdown();
}

public override string MessageStr
{
get
{
return base.MessageStr;
}
set
{
txtMessage.Text = value;
base.MessageStr = value;
}
}
}
}

其中这个窗口名为FormWinGame，DialogWindowBase为一个类
提示“TwoToOnePokerGame.FormWinGame”的分部声明一定不能指定不同的基类

打开FormWinGame.xaml.cs
在class FormWinGame上右键——转到定义
选择转到FormWinGame.g.i.cs文件
把“FormWinGame : System.Windows.Window”改为"FormWinGame : DialogWindowBase"

[Error_Code]

改FormWinGame.xaml的第一行 <window... ></window> 为
<DialogWindowBase....></DialogWindowBase>
要加命名空间

一楼的那个，我怎么定义不到呀？
