将.txt文件从一个文件夹复制到另一个文件夹的代码

DirectoryInfo src = new DirectoryInfo(@"E:\Test\Dir1"); 
DirectoryInfo dest = new DirectoryInfo(@"C:\Dir2"); 
CopyDirectory(src, dest); 
 
 
static void CopyDirectory(DirectoryInfo source, DirectoryInfo destination) 
        { 
            if (!destination.Exists) 
            { 
                destination.Create(); 
            } 
 
            // Copy all files. 
            FileInfo[] files = source.GetFiles(); 
            foreach (FileInfo file in files) 
            { 
                file.CopyTo(Path.Combine(destination.FullName, 
                    file.Name)); 
            } 
 
            // Process subdirectories. 
            DirectoryInfo[] dirs = source.GetDirectories(); 
            foreach (DirectoryInfo dir in dirs) 
            { 
                // Get destination directory. 
                string destinationDir = Path.Combine(destination.FullName, dir.Name); 
 
                // Call CopyDirectory() recursively. 
                CopyDirectory(dir, new DirectoryInfo(destinationDir)); 
            } 
        }

这样的事情：

Something like this:

private static void Main() {
    var source= @"C:\Source\";
    var searchPattern = "*.txt";
    var destination= @"C:\Destination";
    
    foreach (var file in Directory.GetFiles(source, searchPattern)) 
       File.Copy(file, destination);
    
}

干杯，
