[ASP.net教程]ZIP压缩文件夹中上个月的文件,并将备份文件拷贝到服务器


 

遍历文件夹的子文件夹下的所有文件,将上个月的文件集中到一起,然互压缩,并copy到服务器的映射磁盘。

static void Main(string[] args)
{
//原始文件存放的位置
DirectoryInfo theFolder = new DirectoryInfo(@"E:\TestFloder");
//将文件拷贝到该文件夹下
string targetPath = @"D:\test";
DirectoryInfo[] dirInfo = theFolder.GetDirectories();
//遍历文件夹下的子文件夹
foreach (DirectoryInfo folder in dirInfo)
{
FileInfo[] filesInfo = folder.GetFiles();
//遍历子文件夹下的文件
foreach (FileInfo file in filesInfo)
{
//将上个月的文件拷贝到
if (file.CreationTime.ToShortDateString().Equals(DateTime.Now.AddMonths(-1).ToShortDateString()))
{
if (!CopyFile(file, targetPath))
{
//log 复制文件失败
}
else
{
file.Delete();
}
}
}
}


string zipFilePath = @"D:\" + DateTime.Now.AddMonths(-1).ToString("yyyyMMdd") + ".zip";
string remotePath = @"\\127.1.0.0" + @"D:\" + DateTime.Now.AddMonths(-1).ToString("yyyyMMdd") + ".zip";

if (!ZipFiles(targetPath, zipFilePath))
{
//压缩文件失败
}
else
{
//压缩文件成功
//将压缩后的文件拷贝到映射的服务器磁盘
if (!CopyFile(zipFilePath, remotePath))
{
//Copy失败
}
else
{
//copy成功
//删除原有的
File.Delete(zipFilePath);
}

}
