Assigning value to a Variable from SqlDataReader

[Polariss]

How do I assign a value to a variable from the SqlDataReader.Read() method?? In Visual Basic it was done like this:

while sReader.Read()
     Dim s As String = sReader("fieldnamefromdatabase")
end while

I have tried converting this statement from VB to C# with no luck. Does anyone know how to perform this action.

I have tried a couple of other things as well but here is the one I tried first.

string s;
while (sReader.Read == true)
{
s = sReader["fieldnamefromdatabase"];
}

Any help is appreciated!!
