All suggestions were great and thansk for all the advise but this was perfect:
所有的建议都很棒，感谢所有的建议，但这很完美：
if (checkBox3.Checked)
{
string[] lines = File.ReadAllLines(@"C:\NCR.txt");
foreach (string line in lines)
{
string[] files = Directory.GetFiles(textBox2.Text, line + "*.txt");
foreach (string file in files)
{
FileInfo file_info = new FileInfo(file);
File.Copy(file, @"C:\InPrep\" + textBox1.Text + "\text\" + file_info.Name);
}
}
}

//FileInfo & DirectoryInfo are in System.IO
//This is something you should be able to tweak to your specific needs.
static void CopyFiles(DirectoryInfo source,
DirectoryInfo destination,
bool overwrite,
string searchPattern)
{
FileInfo[] files = source.GetFiles(searchPattern);
//this section is what's really important for your application.
foreach (FileInfo file in files)
{
file.CopyTo(destination.FullName + "\" + file.Name, overwrite);
}
}
This version is more copy-paste ready:
这个版本更适合复制粘贴：
static void Main(string[] args)
{
DirectoryInfo src = new DirectoryInfo(@"C:\temp");
DirectoryInfo dst = new DirectoryInfo(@"C:\temp3");
/*
* My example NCR.txt
* *.txt
* a.lbl
*/
CopyFiles(src, dst, true);
}
static void CopyFiles(DirectoryInfo source, DirectoryInfo destination, bool overwrite)
{
List<FileInfo> files = new List<FileInfo>();
string[] fileNames = File.ReadAllLines("C:\NCR.txt");
foreach (string f in fileNames)
{
files.AddRange(source.GetFiles(f));
}
if (!destination.Exists)
destination.Create();
foreach (FileInfo file in files)
{
file.CopyTo(destination.FullName + @"\" + file.Name, overwrite);
}
}

string sourceDir = @"c:\";
string destDir = @"c:\TestDir";
var r = Directory.GetFiles(sourceDir, "red*.txt"); //Replace this part with your read from notepad file
foreach (var s in r)
{
var sourceFile = new FileInfo(s);
sourceFile.CopyTo(destDir + "\" + s.Replace(sourceDir, string.Empty));
}
