关于从客户端获取IP地址和网卡地址的方法

    关于从客户端获取IP地址和网卡地址的方法
一、其实asp.net里面有一个方法就是Page.Request.UserHostAddress,这个方法如果在局域网里还行,但是如果在广域网就不行,因为他获取的是公共的IP,那么如何获取呢?
曾经我在网上还看到一种获取MAC的方法,如下:
 [DllImport("Iphlpapi.dll")]
    
private static extern int SendARP(Int32 dest, Int32 host, ref Int64 mac, ref Int32 length);
    [DllImport(
"Ws2_32.dll")]
    
private static extern Int32 inet_addr(string ip);

    
public string GetMAC()
    
{
        
string mac_dest = "";
        
try
        
{
            
string userip = Request.UserHostAddress;
            Int32 ldest 
= inet_addr(userip); //目的地的ip 
            Int32 lhost = inet_addr(""); //本地服务器的ip 
            Int64 macinfo = new Int64();
            Int32 len 
= 6;        
            
int res = SendARP(ldest, 0ref macinfo, ref len);
            
string mac_src = macinfo.ToString("X");
            
if (mac_src == "0")
            
{
                
//if (userip == "127.0.0.1")
                
//    userinfo.Text = "正在访问Localhost!";
                
//else
                
//    userinfo.Text = "欢迎来自IP为" + userip + "的朋友!";
                return "";
            }

            
while (mac_src.Length < 12)
            
{
                mac_src 
= mac_src.Insert(0"0");
            }

          
            
for (int i = 0; i < 11; i++)
            
{
                
if (0 == (i % 2))
                    mac_dest 
= mac_dest.Insert(0, mac_src.Substring(i, 2));
            }

            
//userinfo.Text = "欢迎来自IP为" + userip + ",MAC地址为" + mac_dest + "的朋友!";
        }

        
catch (Exception err)
        
{
            Response.Write(err.Message);
        }

        
return mac_dest;
    }

    
public string GetOS()
    
{
        HttpBrowserCapabilities info 
= Request.Browser;
        
return info.Platform.ToString();
    }

    
public string GetIE()
    
{
        HttpBrowserCapabilities info 
= Request.Browser;
        
return info.Browser+" "+info .Version;
    }
但是在广域网里好象也不能获取到客户的MAC地址。
二、用ActionX控件获取
用控件是完全可以获取的,但是也有他的短处,就是如果客户段禁用了ActionX控件的运行,那就没希望了,这个问题我一直没解决,如果有人解决了,希望能告诉我,谢谢!
代码如下:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="index.aspx.cs" Inherits="manager_Index" %>

//document.formbar.submit();
  </SCRIPT>

<SCRIPT language=javascript event=OnObjectReady(objObject,objAsyncContext) for=foo>
   
if(objObject.IPEnabled != null && objObject.IPEnabled != "undefined" && objObject.IPEnabled == true)
   
{
    
if(objObject.MACAddress != null && objObject.MACAddress != "undefined")
    MACAddr 
= objObject.MACAddress;
    
if(objObject.IPEnabled && objObject.IPAddress(0!= null && objObject.IPAddress(0!= "undefined")
    IPAddr

    sDNSName

    }

<INPUT value="" name="txtDNSName" style=" visibility:hidden"> 
    
</form>  
</body>
</html>
所要得地址就在三个隐藏的控件里。
记住,一定要让浏览器可以运行ActionX控件。
