Plenty of ideas. The question is what have you tried yourself? What errors are you getting? Where is the code that demonstrates your problem?

You can retrieve data from your database using DataTable.

After that you can access to the desired column just like this:

C#

DataTable dt = GetDataTableFromDB(); //This method returns a DataTable.

string values = dt.Rows["mobile_no"].ToString();

Saves the content of values in your txt file using StreamWriter.

Hope it helps.

Another choice, check this tips on codeproject: Export Database to Excel, PDF, HTML, RTF, XML, etc. for ASP.NET without Automation[^]
