c# – 你能把它转换成VB吗？

static RelatedPosts()
{
 Post.Saved += new EventHandler<SavedEventArgs>(Post_Saved);
}

static void Post_Saved(object sender,SavedEventArgs e)
{
 if (e.Action == SaveAction.Update)
 {
  Post post = (Post)sender;
  if (_Cache.ContainsKey(post.Id))
   _Cache.Remove(post.Id);
 }
}

我转换为：

Shared Sub New()
    Post.Saved += New EventHandler(Of SavedEventArgs)(AddressOf Post_Saved)
End Sub


Private Shared Sub Post_Saved(ByVal sender As Object,ByVal e As SavedEventArgs)
    If e.Action = SaveAction.Update Then
        Dim post As Post = DirectCast(sender,Post)
        If _Cache.ContainsKey(post.Id) Then
            _Cache.Remove(post.Id)
        End If
    End If
End Sub

但它给了我一个错误：

公共共享事件Saved()是一个事件,不能直接调用.使用’RaiseEvent’语句来引发事件.

解决方法

用这个

AddHandler Post.Saved,AddressOf Post_Saved

代替

Post.Saved += New EventHandler(Of SavedEventArgs)(AddressOf Post_Saved)
