我有很多在目录中具有相同名称的文件。我想在MyDirectory中压缩(zip等)最后修改的文件。你能帮帮我吗?
我可以压缩文件但不能压缩上次修改的文件:
private void button1_Click(object sender, EventArgs e)
{
FileStream sourceFile = File.OpenRead(@"C:\MyDirectory");
FileStream destFile = File.Create(@"C:\MyDirectory.zip");
GZipStream compStream = new GZipStream(destFile, CompressionMode.Compress);
try
{
int theByte = sourceFile.ReadByte();
while (theByte != -1)
{
compStream.WriteByte((byte)theByte);
theByte = sourceFile.ReadByte();
}
}
finally
{
compStream.Dispose();
}
MessageBox.Show("file is compressed successfully");
}
答案 0 :(得分:1)
获取上次修改的文件:
string lastModified = Directory.EnumerateFiles(path)
.OrderBy(f => File.GetLastWriteTime(f))
.Last();
