谁可以手写C#代码，调用那个WebService接口，，麻烦写一下好吗，我知道我分不够，接口是这样
http://www.webxml.com.cn/WebServices/IpAddressSearchWebService.asmx在google里查过，，查不到，，才在这里发的，，
不要这种调用的1.在你的项目引用出，右键-》添加服务引用
2.填入接口地址，例如：http://www.webxml.com.cn/WebServices/IpAddressSearchWebService.asmx
3.确定后系统会自动生成一个代理类
4.直接在你的cs代码处调用代理类下的方法

Web引用名 ：IpAdress
添加命名空间 using IpAdress;
实例化：
IpAdress.IpAddressSearchWebService ip = new IpAddressSearchWebService();
后台代码： protected void btnIP_Click(object sender, EventArgs e)
{
try
{
string[] strip;
string strtxeip = this.txtip.Text.Trim();
if (strtxeip != null && strtxeip != "")
{
strip = ip.getCountryCityByIp(strtxeip);
}
else
{
strip = ip.getGeoIPContext();
txtip.Text = strip[0];
}
IPAdress.Text = strip[1];
}
catch (Exception ex)
{
Response.Write("查询失败！");
}

返回时如果不是字符串,即强制转换,如返回是DataSet,则string url = "http://www.webservicex.net/globalweather.asmx" ;
string[] args = new string[2] ;
args[0] = "Hangzhou";
args[1] = "China" ;
object result = WebServiceHelper.InvokeWebService(url ,"GetWeather" ,args) ;
DataSet DSRe=(DataSet)result; 方法三：URL Behavior 属性
如果知道服务的方法和参数,只是调用的URL网址会随时变化,那么可以手工创建一个服务,添加上对应的的方法和传入参数,然后引入到项目中,就可以直接开发,在创建服务的实例化时,才修改对应的URL即可.例如服务中有个方法叫GetTax,那么就可以这样改:GetTax.GetTax GetTax1 = new GetTax.GetTax();
GetTax1.Url = "http://" + WebIp1 + "/pub_wa_gspsp1/gettax.asmx"; //动态引入服务器
DataSet DS1 = GetTax1.GetTaxMx(Bm1, OldBz, Fpl, SLx, StaDa, EndDa); //调用服务器返回开票数据

可以问一下这个是什么意思吗？为什么要把这个变成字节型的数组啊 byte[] buff
简单理解的话Stream.Write方法第一个参数需要的就是byte[]所以得转换。
