Hi You can also get the file count in the Directory and prepare a new name for your file.

C#

string[] strFileNames = Directory.GetFiles("D:\\SaveImageOutPutFolder\\" + ConfigurationManager.AppSettings["SaveImagefolderPath"], "MytxtFile*.*");

C#

string strNewFileName = "MytxtFile" + (strFileNames.Length + 1).ToString();

Use the following to create new file name

C#

string _newfilename=System.IO.Path.GetTempFileName();

It might be helpful,

C#

static string GenerateFilenameUsingGuid(string prefix, string extension)
{
     return string.Concat(prefix, Guid.NewGuid().ToString().Replace("-", string.Empty), extension);
}

static string GenerateFilenameUsingRandomNumber(string prefix, string extension)
{
     return string.Concat(prefix, new Random().Next(), extension);
}

:)

You can add Time stamp to file name. This will help you to generate random files.

C#

string fileName="MyFile" + DateTime.Now.ToFileTime().ToString().Replace(" ","") + ".txt";
