Android调用Webservice发送文件

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

System.Web.Services;
using System.IO;

二.客户端
要使用 ksoap2库
