这段C#代码如何转换成vb.net?

[dombo]

网络上的转换工具都转换不了这段代码

//定义
Public Delegate Sub BeginRequestHandler(ByVal request As System.Net.HttpWebRequest)
Public Event BeginRequest As BeginRequestHandler

//要转换的语句
HttpUtils.HttpWebRequest.BeginRequestHandler temp = new HttpUtils.HttpWebRequest.BeginRequestHandler(request=>{
request.Referer = string.Format("{0}/Login.aspx", url);
});

HttpRequest.BeginRequest += temp;

最主要这个request=>是什么意思?

转化的结果

Dim temp As New HttpUtils.HttpWebRequest.BeginRequestHandler(Function(request) Do 
    request.Referer = String.Format("{0}/Login.aspx", url) 
End Function) 

HttpRequest.BeginRequest += temp

网上能找到的在线转换网址都试过了,语法错误
SharpDevelop的转换功能也试过,一样语法错误

[dombo]

再顶一下

这句话是什么用处呢？
给控件添加函数体？
可以用addhandler实现

addhandler HttpUtils.HttpWebRequest.BeginRequest,addressof request
Function request 
    '这写你的函数体 
End Function

λ表达式
跟匿名方法的作用一样。

public void DoSomething(System.Net.HttpWebRequest request)
{
   request.Referer = string.Format("{0}/Login.aspx", url);
} 

HttpUtils.HttpWebRequest.BeginRequestHandler temp =
    new HttpUtils.HttpWebRequest.BeginRequestHandler(DoSomething);

HttpRequest.BeginRequest += temp; 

λ表达式 减少代码输入量，
在List<int>查找第一个大于0的元素的Index

List<int> list = new List<int>();
list.Add(0);
list.Add(-1);
list.Add(2);
int index1, index2;
index1 = list.FindIndex(t => { return t > 0; });
//类似下面的匿名方法
index2 = list.FindIndex(delegate(int t) { return t > 0; });
