Removing Duplicate Rows in data table using c#

To find distinct records based column or columns, i have found this is the simplest way.

string[] columns=new string[dtTable .Columns.Count];
       int i=0;
       foreach (DataColumn dc in dtTable.Columns)
       {
           columns[i++] = dc.ColumnName.Trim();
       
       }
       
       dtTable = dtTable.DefaultView.ToTable(true, columns);
       return dtTable;
