c# - 接口(interface)从 vb.net 到 c# 的转换

Question

我有一个控件可以覆盖 protected GetService 方法并将其分配给 IServiceProvider 接口(interface):

Class MyControl
    Inherits Control
    Implements IServiceProvider

    Protected Overrides Sub GetService(t as Type) as Object Implements IServiceProvider.GetService
    End Sub

End Class

我正在努力将其转换为 C#。我试过隐式与显式，但我一定是语法错误。

你会这样做:

class MyControl : Control, IServiceProvider
{
     // Explicitly implement this
     object IServiceProvider.GetService(Type t)
     {
          // Call through to the protected version
          return this.GetService(t);
     }

     // Override the protected version...
     protected override object GetService(Type t)
     {
     }
}

也就是说，Control 已经实现了 IServiceProvider(通过 Component)。你真的可以这样做:

class MyControl : Control
{
     protected override object GetService(Type t)
     {
     }
}
