1.利用Rar压缩文件
/// <summary>
/// 使用Rar压缩文件
/// </summary>
/// <param name="fromFilePath">待压缩文件路径</param>
/// <param name="rarFilePath">压缩后的文件路径</param>
/// <returns>返回压缩结果</returns>
public string RarFile(string fromFilePath, string rarFilePath)
{
try
{
//Rar程序安装目录
var fileName = @"C:\Program Files\WinRAR\rar.exe";
//命令行参数
var arguments = " a " + rarFilePath + " " + fromFilePath;
var startInfo = new ProcessStartInfo();
startInfo.FileName = fileName;
startInfo.Arguments = arguments;
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
//打包文件存放目录
var dir = Path.GetDirectoryName(fromFilePath);
if (dir != null)
{
startInfo.WorkingDirectory = dir;
var process = new Process { StartInfo = startInfo };
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardError = true;
process.StartInfo.UseShellExecute = false;
process.StartInfo.CreateNoWindow = true;
process.Start();
process.WaitForExit();
var output = process.StandardOutput.ReadToEnd();
var errMsg = process.StandardError.ReadToEnd();
process.Close();
//rar可能是中文版或英文版
if (output.IndexOf("完成", StringComparison.Ordinal) > -1 || output.ToLower().IndexOf("done", StringComparison.Ordinal) > -1)
{
return "完成";
}
}
return "文件所在目录不存在";
}
catch (Exception ex)
{
return ex.Message;
}
}
调用方法：
//将文件压缩到同级目录
var fromFile = "";
var dir = Path.GetDirectoryName(fromFile);
var name = Path.GetFileNameWithoutExtension(fromFile);
var tofile = dir.Combine(name + ".zip");
var result = RarFile(fromFile, tofile);
2.通过FTP上传文件
/// Ftp上传文件
/// </summary>
/// <param name="localFile">本地文件路径</param>
/// <param name="ftpServer">ftp服务器地址</param>
/// <param name="ftpUserName">ftp用户名</param>
/// <param name="ftpPassword">ftp用户密码</param>
/// <returns></returns>
public string Upload(string localFile, string ftpServer, string ftpUserName, string ftpPassword)
{
if (File.Exists(localFile))
{
var fileInfo = new FileInfo(localFile);
using (var fileStream = fileInfo.OpenRead())
{
var length = fileStream.Length;
var request = (FtpWebRequest)WebRequest.Create("ftp://" + ftpServer + "/" + fileInfo.Name);
request.Credentials = new NetworkCredential(ftpUserName, ftpPassword);
request.Method = WebRequestMethods.Ftp.UploadFile;
request.UseBinary = true;
request.ContentLength = length;
request.Timeout = 10 * 1000;
try
{
var stream = request.GetRequestStream();
var BufferLength = 1024 * 1024; //1M
var b = new byte[BufferLength];
int i;
while ((i = fileStream.Read(b, 0, BufferLength)) > 0)
{
stream.Write(b, 0, i);
}
stream.Close();
stream.Dispose();
return "上传完毕";
}
catch (Exception ex)
{
return ex.Message;
}
}
}
return "本地文件不存在!";
}
通过以上方式，再做个定时任务，可以将服务器文件定期备份到指定的ftp上。
