一服务器端C#
这里有三个上传方法1.uploadFile( byte []bs, String fileName); PC机操作是没有问题2. uploadImage(String filename,String image); //android大于1M上传会出问题(内存溢出),把文件件转换为Base64字符串上传3. uploadResume(String filename, String image, int tag); //android可以传大文件using System;using System.Collections.Generic;using System.Web;using System.Web.Services;using System.IO;////// Summary description for service1///[WebService(Namespace = "")][WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.// [System.Web.Script.Services.ScriptService]public class service1 : System.Web.Services.WebService { public service1 () { //Uncomment the following line if using designed components//InitializeComponent();}[WebMethod]public string HelloWorld(string str1) { return str1+"成功";}[WebMethod]public int Add(int a, int b){ return a + b;}[WebMethod]public int uploadFile( byte []bs, String fileName){ FileStream out1 =null;try { String path=String.Format("{0:yyyyMMdd_hhmmss}_{1}",DateTime.Now,fileName);String newFile = HttpContext.Current.Server.MapPath("upload/"+path); // 上传文件存放路径out1 = new FileStream(newFile, FileMode.CreateNew, FileAccess.Write);try { out1.Write(bs,0,bs.Length);} catch (IOException e) { // TODO Auto-generated catch block;}} catch (FileNotFoundException e) { // TODO Auto-generated catch blockreturn - 1 ;} finally { if (out1 != null ) { try { out1.Close();} catch (IOException e) { // TODO Auto-generated catch block}}}return 0 ;}[WebMethod] //android大于1M上传会出问题(内存溢出)public int uploadImage(String filename,String image){ FileStream out1 =null;byte []bs=Convert.FromBase64String(image);try { String path=String.Format("{0:yyyyMMdd_hhmmss}_{1}",DateTime.Now,filename);String newFile = HttpContext.Current.Server.MapPath("upload/"+path); // 上传文件存放路径out1 = new FileStream(newFile, FileMode.CreateNew, FileAccess.Write);try { out1.Write(bs,0,bs.Length);} catch (IOException e) { // TODO Auto-generated catch block;}} catch (FileNotFoundException e) { // TODO Auto-generated catch blockreturn - 1 ;} finally { if (out1 != null ) { try { out1.Close();} catch (IOException e) { // TODO Auto-generated catch block}}}return 0 ;}[WebMethod] //断点续传public int uploadResume(String filename, String image, int tag){ FileStream out1 = null;byte[] bs = Convert.FromBase64String(image);try{ String newFile = HttpContext.Current.Server.MapPath("upload/" + filename); // 上传文件存放路径if (tag == 0){ if(File.Exists(filename))File.Delete(filename);out1 = new FileStream(newFile, FileMode.CreateNew, FileAccess.Write);}else{ out1 = new FileStream(newFile, FileMode.Append, FileAccess.Write);}try{ out1.Write(bs, 0, bs.Length);}catch (IOException e1){ // TODO Auto-generated catch block;}}catch (FileNotFoundException e2){ // TODO Auto-generated catch blockreturn -1;}finally{ if (out1 != null){ try{ out1.Close();}catch (IOException e){ // TODO Auto-generated catch block}}}return tag;}}二.客户端 要使用 ksoap2库
