If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:

I've got a project in c# which is making use of another project written in vb.net. I am currently able to modify both.I've got a method in the VB project like:
Public Sub MethodName(ByVal param1 As String, ByRef param2 As String)
param2 = param1 + 1
End Sub
I am not able to call this method using the out keyword from C#:
public void CallOtherMethod()
{
string param1 ="test";
string param2;
provider.AddTransaction(param1, out param2);
}
Shouldn't the ByRef keyword in VB.Net have the capabilities of both "ref" and "out"?
