| How to write Sql In Operator in Linq |
| 2012-05-01 00:22:00 |
As we always go through in operator to pass some parameter to in like
select id,name,address from tbl_address where name in ('anand','kumar') . To implements this query in linq we need to create a list with the type of sql column datatype. If Name is Varchar then go with List ,if id int the go with list
its very similar to sql statements but in WHERE class of linq we need to pass listObj.Contains()
Please try the same like
DbClassDataContext objDB = new DbClassDataContext();
protected void Page_Load(object sender, EventArgs e)
{
List listobj = new List();
listobj.Add("Anand");
listobj.Add("Kumar");
listobj.Add("Siv");
var litsData = from i in objDB.GetTable()
where listobj.Contains(i.Name) // note this point
select new { i.Name,i.Address};
foreach (var i in litsData)
{
Response.Write(i.Name.ToString()+", "+i.Address.ToString() + "
");
}
}
in the above example I am using Name that is type of varchar so I create List objList . For searching data I use where l...
