Code to export datatable to CSV format.


Hello friends we all go for a complex coding for exporting the data into excel sheet. Some times we face a problem that we are not having the interop dll for export to excel. So here is a solution for all of us which will help in exporting the data into .csv format.

Using the code  

Here is a simple code.

var lines = new List<string>();

string[] columnNames = dataTable.Columns.Cast<datacolumn>().
                                  Select(column => column.ColumnName).

var header = string.Join(",", columnNames);

var valueLines = dt.AsEnumerable()
                   .Select(row => string.Join(",", row.ItemArray));            
lines.AddRange(valueLines );


This is the most simplest code that i have used. You all will also find this interesting.
