Reading file names is pretty easy:

C#

string[] files = Directory.GetFiles(@"D:\Temp");

If you want the filename without the path then add:

C#

string[] justFiles = files.Select(f => Path.GetFileName(f)).ToArray();

Or

C#

string[] justFiles = files.Select(f => Path.GetFileNameWithoutExtension(f)).ToArray();

Saving to Excel is more complex, but this may help simplify it: Write Data to Excel using C#[^]

Another way is to get all file names into DataTable[^] and than use CopyFromRecordset method[^] for MS Excel range.

C#

//get files into datatable
string[] filePaths = Directory.GetFiles(@"F:\\Download\\", "*.txt",SearchOption.AllDirectories);
DataTable dt = new DataTable("Files");
DataColumn dc = new DataColumn("File", Type.GetType("String"));
dt.Columns.Add(dc);
for (int i = filePaths.GetLowerBound(0); i < filePaths.GetUpperBound(0); i++)
{
    DataRow dr = dt.NewRow();
    dr["File"] = filePaths[i];
}

//create new workbook and insert data using CopyFromRecordset method ;)
//follow the link: http://support.microsoft.com/kb/306023

Please, follow this link: How to transfer data to an Excel workbook by using Visual C# 2005 or Visual C# .NET[^]
