RT：WinForm程序中Button控件默认鼠标点击，如何让其识别回车键；我要使用回车键（或者其他的按键）也可以执行操作?

重写button的keydown方法，自己指定响应的快捷键。

两种方法：

1.在pictureBox1的MouseDown事件里得到坐标：

private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
{
int x = e.X;
int y = e.Y;
}

//x，y就是相对pictureBox1的坐标

2.先得到相对于屏幕的坐标，然后通过pictureBox1.PointToClient()转换到相对于pictureBox1的坐标：

Point mx = MousePosition;
Point mx2 = pictureBox1.PointToClient(mx);

//mx2就是相对pictureBox1的坐标

我也没用WPF做过项目,我刚试了简单的小程序:
登录界面,刚开始鼠标定位在帐号输入框,按下回车键自动到密码输入框,再按下回车键自动定位到登录按钮

重点代码

1. <Grid>
   
2. <TextBlock HorizontalAlignment="Left" Margin="23,47,0,0" TextWrapping="Wrap" Text="帐号" VerticalAlignment="Top" RenderTransformOrigin="0.436,-0.75"/>
   
3. <TextBox Name="txtAccount" HorizontalAlignment="Left" Height="23" Margin="100,44,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="156" KeyDown="txtAccount_KeyDown"/>
   
4. <TextBlock HorizontalAlignment="Left" Margin="23,93,0,0" TextWrapping="Wrap" Text="密码" VerticalAlignment="Top"/>
   
5. <PasswordBox Name="txtPassword" HorizontalAlignment="Left" Height="23" Margin="100,90,0,0" VerticalAlignment="Top" Width="156" KeyDown="txtPassword_KeyDown"/>
   
6. <Button Name="btnLogin" Content="登录" HorizontalAlignment="Left" Margin="100,154,0,0" VerticalAlignment="Top" Width="75" Click="btnLogin_Click"/>
   
7. <Button Name="btnCancel" Content="取消" HorizontalAlignment="Left" Margin="181,154,0,0" VerticalAlignment="Top" Width="75"/>
   
8. </Grid>

复制代码

1. private void winLogin_Loaded(object sender, RoutedEventArgs e)
   
2. {
   
3. txtAccount.Focus();
   
4. }
   
5. 
   
6. private void txtAccount_KeyDown(object sender, KeyEventArgs e)
   
7. {
   
8. if (e.Key == Key.Return)
   
9. {
   
10. txtPassword.Focus();
    
11. }
    
12. }
    
13. 
    
14. private void txtPassword_KeyDown(object sender, KeyEventArgs e)
    
15. {
    
16. if (e.Key == Key.Return)
    
17. {
    
18. btnLogin.Focus();
    
19. }
    
20. }

复制代码

说明:
       KeyDown事件中可以:if (e.Key == Key.Return)你将断点定在此,可以看到你点击的键盘事件.貌似Key.Return就是回车键吧.
      

设置窗体的AcceptButton属性即可！
