C# 最简单的修改webbrowser标志

添加引用
using System.Runtime.InteropServices;
声明useragent标志
 private string userAgent = "Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; Trident/6.0)";
添加API操作
[DllImport("urlmon.dll", CharSet = CharSet.Ansi)]
private static extern int UrlMkSetSessionOption(int dwOption, string pBuffer, int dwBufferLength, int dwReserved);
       
private const int UrlmonOptionUseragent = 0x10000001;

public void ChangeUserAgent(string agent)
{
UrlMkSetSessionOption(UrlmonOptionUseragent, agent, agent.Length, 0);
}





private void Form1_Load(object sender, EventArgs e)
{
ChangeUserAgent(userAgent);

} 

　　最近看了下某安全狗绕过神器。用的方法就是利用百度的useragent，安全狗好像默认放行。所以导致了可以利用这个来注入检测之类的。用上面方法，可以轻轻松松绕过~~
