Hi,

I am already using below code to find files within a folder in asp.net C#.

It might be helpful to you too.

public string GetOpenOrders(string FileName)
{
string DirectoryPath = HttpContext.Current.Server.MapPath("~/LocalData");
FileInfo[] Files = new DirectoryInfo(DirectoryPath).GetFiles();
List LstFiles = new List();
if (Files.Length == 0)
return "-1";
foreach (FileInfo S in Files)
{
if (S.Name.ToLower().StartsWith(FileName.ToLower()))
LstFiles.Add(S.Name.ToUpper().Remove(S.Name.Length - 4, 4));
}
return LstFiles;
}

Hope it helps.
Thanks.

Check file existance using below code.

if(File.Exists(filePath))

{

   string[] dirs = Directory.GetFiles(directoryPath, filename);

   if(dirs.length>0)

   //do your stuff

}

```
string[] files = System.IO.Directory.GetFiles(path, "*.txt");
```
Url for ref
http://www.csharp-examples.net/get-files-from-directory/

// See if this file exists in the same directory.
if (File.Exists("TextFile1.txt"))
{
Console.WriteLine("The file exists.");
}
// See if this file exists in the C:\ directory. [Note the @]
if (File.Exists(@"C:\tidy.exe"))
{
Console.WriteLine("The file exists.");
}
// See if this file exists in the C:\ directory [Note the '\\' part]
bool exists = File.Exists("C:\\lost.txt");
Console.WriteLine(exists);
