This will help you only when you have to filter distinct records based on specified fields.
e.g. I have a table called UserDetail which contains the following fields:

UserID | Name | Mobile | Email | City | State

Now I want to only display distinct records with Name, City and State, then you can use:



string[] TobeDistinct = {"Name","City","State"};

DataTable dtDistinct = GetDistinctRecords(DTwithDuplicate, TobeDistinct);

 

//Following function will return Distinct records for Name, City and State column.

public static DataTable GetDistinctRecords(DataTable dt, string[] Columns)

   {

       DataTable dtUniqRecords = new DataTable();

       dtUniqRecords = dt.DefaultView.ToTable(true, Columns);

       return dtUniqRecords;

   }
