首先需要在项目中引用System.Windows.Forms，System.Drawing;
  1 using System;
  2 using System.Collections.Generic;
  3 using System.Linq;
  4 using System.Text;
  5 using System.Windows;
  6 using System.Windows.Controls;
  7 using System.Windows.Data;
  8 using System.Windows.Documents;
  9 using System.Windows.Input;
 10 using System.Windows.Media;
 11 using System.Windows.Media.Imaging;
 12 using System.Windows.Navigation;
 13 
 14 using System.Windows.Shapes;
 15 using System.Drawing;

105                 {
106                     this.Visibility = Visibility.Hidden;
107                 }
108                 else
109                 {
110                     this.Visibility = Visibility.Visible;
111                     this.Activate();
112                 }
113             }
114         }
115     }
116 }
以上代码并非用户控件代码，只需加在主窗体中即可。
