Solution 2

suppose ds is your dataset object and you want to query in 1st table i.e. at index 0. Then,

C#

DataView dv = ds.Tables[0].DefaultView;
dv.RowFilter = "[Name] LIKE 'Sanjay%'";

DataTable dtFiltered = dv.ToTable();

dtFiltered table will contain filtered rows.

Solution 1

ds.table[0].Where(row => row.StringColumn.StartsWith("prefix"))

or

C#

ds.table[0].Where(p => p.UserName.StartsWith("Fr") && p.UserName.EndsWith("d") && p.UserName.Length == 4)

ds is your dataSet and table[0] is 0th table of dataset and StringColumn is Col name
