Get distinct records from datatable

Question

Hello Everyone, 

 

I have a data table with the following columns and rows as I showed below.  

DataTable dt = new DataTable();
           try
           {
               dt.Columns.Add("f1");
               dt.Columns.Add("f2");
               dt.Columns.Add("f3");

               dt.Rows.Add("ABC", "ATAG", "");
               dt.Rows.Add("abc", "atag", "");
               dt.Rows.Add("abc", "ATAGChild", "");



           }
           catch (Exception)
           {

               throw;
           }

I want to get distinct records from this data table (check case sensitive information) and I need the following expected output as a result in the data table.

 

Expected Output: 

 

f1	f2
ABC	ATAG
abc	ATAGChild

 

where f1 and f2 is my column.
