c# – 你能把它转换成VB吗？

概述static RelatedPosts(){ Post.Saved += new EventHandler<SavedEventArgs>(Post_Saved);}static void Post_Saved(object sender, SavedEventArgs e){ if (e.Action == SaveAction.Update) { Post post = (

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 SubPrivate 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 IfEnd 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)
