I just want to know what's the lambda expression of Select * from TableName.
Like in plain LINQ it will be var res=from s in db.StudentDatas select s;
here StudentData is name of the table.
Thanks.

select (s => new SelectListItem { Value = s. ID. ToString(), Text = s.Name} ); select (s => new SelectListItem { Value = s.ID + "", Text = s.Name} );
A lambda expression is a short block of code which takes in parameters and returns a value. Lambda expressions are similar to methods, but they do not need a name and they can be implemented right in the body of a method.
The lambda expression isn't needed:
var res = db.StudentDatas;
You could use one but it would be rather pointless:
var res = db.StudentDatas.Select(s => s);
The compiler will translate it to something along these lines:
db.StudentDatas.Select(s => s)
The translation to SQL is done by the Base Class Library. SQL, of course, does not use lambda expressions...
