How to use an array variable as a case parameter

[KKW]

Good morning all!

VS2010
.NET 3.5

Here is a snippet in VB.Net that works, but the C# version does not.
VB.Net:

              
Dim a(8) As String
Dim b As String
Dim c As Short
		
    a(0) = "There"
    a(1) = "Not Here"
    a(2) = "Over Here"
		
    b = "Not Here"
    Select Case b
        Case a(0)
            c = 1
        Case a(1)
            c = 2
        Case a(2)
            c = 3
    End Select

The C# code:

The Case a[x]: is the problem.
I'm getting an error: "A constant value is expected".

string a = new string[8];
string b;
int c;
		
    a[0] = "There";
    a[1] = "Not Here";
    a[2] = "Over Here";
		
    b = "Not Here";

switch (b)
{
    case a[0]:
        c = 1;
        break;
    case a[1]:
        c = 2;
        break;
    case a[2]:
        c = 3;
        break;
}

Can anyone help?
