[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,0,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。
