Question

Asp.net如何获取客户端的IP

Answer 1

大型项目中一般这样获取
/// <summary>
/// 获取客户端IP
/// </summary>
public static string ClientIP
{
get
{
string result = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if (null == result || result == String.Empty)
{
result = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
}

if (null == result || result == String.Empty)
{
result = HttpContext.Current.Request.UserHostAddress;
}
return result;
}
}

我写的是属性

Answer 2

string loginIP = Request.UserHostAddress;
