Request.ServerVariables [REMOTE_ADDR]。ToString（）;

Request.ServerVariables（ REMOTE_ADDR）
或
Request.UserHostAddress

您可以使用 Request.ServerVariables [REMOTE_ADDR] 或 Request.ServerVariables [HTTP_X_FORWARDED_FOR] 。

见此功能：

  public   static   string  GetIPAddress（）
 {
 System.Web.HttpContext context = System.Web.HttpContext.Current; 
 string  sIPAddress = context.Request.ServerVariables [  HTTP_X_FORWARDED_FOR跨度>]; 
 if （ string  .IsNullOrEmpty（sIPAddress））{
 return  context.Request.ServerVariables [  REMOTE_ADDR]; 
}  else  {
 string  [] ipArray = sIPAddress.Split（ new  Char [] {' ，'}） ; 
 return  ipArray [ 0 ]; 
} 
}

HI all can anyone help me out how to get the client ip address in asp.net web application


thank you in advanvce

Request.ServerVariables["REMOTE_ADDR"].ToString();

Request.ServerVariables("REMOTE_ADDR")
or
Request.UserHostAddress

You can get it using Request.ServerVariables["REMOTE_ADDR"] or Request.ServerVariables["HTTP_X_FORWARDED_FOR"].
See this function:

public static string GetIPAddress()
{
    System.Web.HttpContext context = System.Web.HttpContext.Current;
    string sIPAddress = context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
    if (string.IsNullOrEmpty(sIPAddress)) {
        return context.Request.ServerVariables["REMOTE_ADDR"];
    } else {
        string[] ipArray = sIPAddress.Split(new Char[] { ',' });
        return ipArray[0];
    }
}
