通过Web Service如何上传一个文件啊？

[Soft21]

我想用Dot Net 写一个Web Service,让调用者给我上传一个文件。
请问我的Web Service该如何实现？

在客户端（winform/asp.net)将文件化为byte[]
调用webservice的upload（byte[] file）方法,
将byte[]再组合成文件
[WebMethod]
public void Upload_file(Files file,byte[] filebyte)//上传文件
{
try
{
file.upload_time=DateTime.Now.ToString();
SelectCommand.CommandText="insert into DOWNLOAD_FILES(type,upload_time,fsize,clicktimes,discription,ownerid,property,filename) values('"+file.type+"','"+file.upload_time+"',"+file.fsize+","+file.clicktimes+",'"+file.discription+"',"+file.ownerID+",'"+file.property+"','"+file.filename+"')";
SelectCommand.Connection=Connect;
Connect.Open();
SelectCommand.ExecuteNonQuery();

SelectCommand.CommandText="select MAX(id) from DOWNLOAD_FILES";
SelectCommand.Connection=Connect;
int id=(int)(SelectCommand.ExecuteScalar());
FileStream s=new FileStream("C:\\Inetpub\\wwwroot\\files\\"+id,FileMode.Create);
s.Write(filebyte,0,filebyte.Length);
s.Close();
Connect.Close();
}
catch(Exception Upload_file_ex)
{
throw Upload_file_ex;
}
}



ASP.Net调用webservice:
private void Button1_Click(object sender, System.EventArgs e)
{
if(uplTheFile.PostedFile.ContentLength==0)Response.Write("请选择文件!");
else
{
Stream sfile=uplTheFile.PostedFile.InputStream;
byte[] filebyte=new byte[uplTheFile.PostedFile.ContentLength];
sfile.Read(filebyte,0,uplTheFile.PostedFile.ContentLength);
MICService.Files ff=new MICService.Files();
ff.fsize=uplTheFile.PostedFile.ContentLength;
ff.clicktimes=0;
ff.ownerID=Convert.ToInt32(Session["id"]);
ff.discription=dis.Text;
ff.type=type.SelectedItem.Value;
ff.property =property.SelectedItem.Value;
string [] split=(uplTheFile.PostedFile.FileName.ToString()).Split(new char[]{'\\'}) ;
ff.filename=split[split.Length-1];
ss.Upload_file(ff,filebyte);
Response.Redirect("netdisk.aspx");
}
}
