【原】借鸡生蛋 C# 转 VB 和 C# 转 VB 【有源码】

本文主要是介绍【原】借鸡生蛋 C# 转 VB 和 C# 转 VB 【有源码】，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

思路：模拟数据提交，分析回发数据，提取结果。

我们先看这个网站，

http://www.developerfusion.com/tools/convert/csharp-to-vb/ 【Convertor】

打开【Convertor】的站点，使用firebug 或 httpwatch 分析出post 数据，这里请参考如下代码：

AutomaticClipboard=ture&AutomaticClipboard=false&Code=" + code

上一行代码很重要，目的是为了模拟提交数据，再看这行，

StreamReader responseStream = new StreamReader(request.GetResponse().GetResponseStream());

这行代码目的是得到回发数据，好了，其他就不多说了，贴代码：

CONVERTOR
<%@ Page Language="C#" ValidateRequest="false" %>

<%@ Import Namespace="System.Net" %>
<%@ Import Namespace=" System.IO" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">
    protected void btnConvert_Click(object sender, EventArgs e)
    {
        string url = "http://www.developerfusion.com/tools/convert/csharp-to-vb/";
        WebRequest request = HttpWebRequest.Create(url);
        request.Method = "post";
        string code = txtCode.Text.Trim();
        request.ContentType = "application/x-www-form-urlencoded";
        string postedData = "AutomaticClipboard=ture&AutomaticClipboard=false&Code=" + code;
        byte[] requestContent = System.Text.Encoding.ASCII.GetBytes(postedData);
        request.ContentLength = requestContent.Length;
        Stream requestStream = request.GetRequestStream();
        requestStream.Write(requestContent, 0, requestContent.Length);
        //read the response;
        StreamReader responseStream = new StreamReader(request.GetResponse().GetResponseStream());
        string response = responseStream.ReadToEnd();
        responseStream.Close();
        int firstdiv = response.IndexOf("<ul", response.IndexOf("code-view"));
        int lastdiv = response.IndexOf("</ul>", firstdiv);
        string result = response.Substring(firstdiv, lastdiv - firstdiv);
        ltlResult.Text = result;

    }
</script>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:TextBox ID="txtCode" runat="server" Height="204px" TextMode="MultiLine" Width="586px"></asp:TextBox>
        <br />
        <asp:Button ID="btnConvert" runat="server" OnClick="btnConvert_Click" Text="Convert" />
        <br />
        <asp:Literal ID="ltlResult" runat="server"></asp:Literal>
    </div>
    </form>
</body>
</html>

当然其实网上还有有很多C#和VB.NET互转工具：
