[WebMethod(Description="上传并保存图片文件")]
??public bool SaveFile(byte[] binData,string fileName){
???bool success=false;???

???string savePath=System.Configuration.ConfigurationSettings.AppSettings["UploadDirectory"];
???if(savePath==null) savePath="Photo";
???if(savePath.IndexOf("://")<0) savePath=Server.MapPath(savePath);//不是绝对路径
???if(!savePath.EndsWith("//")) savePath += "//";

???if(!Directory.Exists(savePath)){
????throw new Exception("服务器端没有找到有效的保存路径！");
???}
???
???FileStream fileStream=null;
???try{
????fileStream=new FileStream(savePath + fileName,FileMode.Create,FileAccess.Write);
????//write the file
????fileStream.Write(binData,binData.Length);
????fileStream.Flush();//clear the buffer,write the data to the hard disk
????success=true;
???}catch(Exception ex){
????throw new Exception(ex.Message);?
???}finally{
????fileStream.Close();
???}
???return success;
???
??}??

解决思路：编写WebService过程SaveFile(byte[] binData,string fileName0;客户端直接用调用，把数据流作参数传上来就完了。
