if(url.IndexOf("&",url.IndexOf(param)+param.Length)>0)

url1=url.Substring(0,url.IndexOf(param)-1)+url.Substring(url.IndexOf("&",url.IndexOf(param)+param.Length)+1);

}

{
12
url1=url.Substring(0,url.IndexOf(param)-1);
13
}
14
return url1;
15
}
16
else
17
{
18
return url1;

}
要去除多个参数,这么使用就可以了。buildurl(buildurl(buildurl(url,param1),param2),param3)
