Are your sure this mail id is present inside the list? Also don't post email in a forum, you will get many spams.

What is "Inspinias"? What is the code that defines it?

One possible problem is that the database does not have a record that matches your where clause EXACTLY.

You can retrieve all the results by using select i or you can select fields as follows:

C#

var b = from i in Inspinias
        where i.Email.Contains("jayesh@gmail.com")
        select new
        {
          i_name = i.Name
        };

//retrieve it as..
foreach (var rec in b)
{
   //rec.i_name;
}

Voted 4, because of select new{} is unnecessary, but you're right that OP needs to loop through the collection of "records" returned via linq query.
