StartsWith is taking only a single pattern. You need to use either an other list or implement a new extension method. You can hind both approaches here: http://stackoverflow.com/questions/4970899/linq-to-sql-query-where-a-string-startswith-an-element-from-a-generic-list[^].

Makes sense if you sue linq to sql. But you did not mention that. You can use OriginalGriff's answer if you can live with it's limitations.

Hi,

Please refere following.

List lostring = new List();
lostring.Add("A");
lostring.Add("B");

List loArrayString = new List();
loArrayString.Add("Abcd");
loArrayString.Add("MNJ");
loArrayString.Add("PQR");
loArrayString.Add("XYZ");
loArrayString.Add("ASDF");

var result = from c in loArrayString
where lostring.Any(s1 => c.StartsWith(s1))
select c;

GridView1.DataSource = result;
GridView1.DataBind();

This will bind grid view with data start with string array "lostring".

There is not String.StartsWith overload which takes multiple string options. You would have to write this as:

C#

var v10 = from a in li.tbl_admin_Brands where a.category.StartsWith("A") ||
                                              a.category.StartsWith("B") ||
                                              a.category.StartsWith("C") select a;
