面介绍一种用Web Services制作的升级程序通过Web Services 升级程序就象读写本机文件一样简单所以我就直接给出代码
Web Services部分代码
using System;
using SystemWeb;
using SystemWebServices;
using SystemWebServicesProtocols;
using SystemIO;
[WebService(Namespace = )]
[WebServiceBinding(ConformsTo = WsiProfilesBasicProfile_)]
public class Service : SystemWebServicesWebService
{
public Service()
{
//如果使用设计的组件请取消注释以下行
//InitializeComponent();
}
/// <summary>
/// 需要升级文件的服务器路径
/// </summary>
private const string UpdateServerPath =d:\\Debug;
[WebMethod(Description = 返回服务器上程序的版本号)]
public string ServerVer()
{
return ;
}
[WebMethod(Description = 返回需更新的文件)]
public string[] NewFiles()
{
DirectoryInfo di = new DirectoryInfo(UpdateServerPath);
FileInfo[] fi = diGetFiles();
int intFiles= fiLength;
string[] myNewFiles = new string[intFiles];
int i = ;
foreach (FileInfo fiTemp in fi)
{
myNewFiles[i] = fiTempName;
SystemDiagnosticsDebugWriteLine(fiTempName);
i++;
}
return myNewFiles;
}
[WebMethod(Description = 返回需更新的文件的大小)]
public int AllFileSize()
{
int filesize = ;
string[] files = DirectoryGetFiles(UpdateServerPath);
foreach (string file in files)
{
FileInfo myInfo = new FileInfo(file);
filesize += (int)myInfoLength / ;
}
return filesize;
}
[WebMethod(Description = 返回给定文件的字节数组)]
public byte[] GetNewFile(string requestFileName)
{
///得到服务器端的一个文件
if (requestFileName != null || requestFileName != )
return getBinaryFile(UpdateServerPath + \\+requestFileName);
else
return null;
}
/// <summary>
/// 返回所给文件路径的字节数组
/// </summary>
/// <param name=filename></param>
/// <returns></returns>
private byte[] getBinaryFile(string filename)
{
if (FileExists(filename))
{
try
{
//打开现有文件以进行读取
FileStream s = FileOpenRead(filename);
return ConvertStreamToByteBuffer(s);
}
catch
{
return new byte[];
}
}
else
{
return new byte[];
}
}
/// <summary>
/// 把给定的文件流转换为二进制字节数组
/// </summary>
/// <param name=theStream></param>
/// <returns></returns>
private byte[] ConvertStreamToByteBuffer(SystemIOStream theStream)
{
int b;
SystemIOMemoryStream tempStream = new SystemIOMemoryStream();
while ((b = theStreamReadByte()) != )
{
tempStreamWriteByte(((byte)b));
}
return tempStreamToArray();
}
}
