1、C#代码如下：

public class logotoimgConverter:IValueConverter   {       //将logo转换为URI       public object Convert(object value, Type targetType, object parameter, string language)       {           logo c = (logo)value;           switch (c)           {               case logo.Baidu:                   return @"/Assets/Baidu.png";                                  case logo.Google:                   return @"/Assets/Google.png";//   /这个才是/正斜杠               default:                   return null;           }       }       public object ConvertBack(object value, Type targetType, object parameter, string language)       {           throw new NotImplementedException();       }   }

2、在XAML中，

resource中有

而在相对应要转换值的绑定的控件加入
