Switch case giving me an error

Question

I have the following type of code:

String strGroup = Request.QueryString["group"];

switch(strGroup.ToString){
    case "Clients":
        // do something here
        break;
    case "Addresses":
        // do something here
    break;
    case "Matters":
        // do something here
    break;
    case "Individuals":
        // do something here
     break;
    case "Organisations":
        // do something here
    break;
    default:
        break;
}

But it's giving the following error:

A value of an integral type expected for switch(strGroup.ToString){

Answer 1

Change it to this:

switch(strGroup.ToString())

ToString() is a method, not a property. Therefore, you need to have the empty parenthesis.

Answer 2

Since strGroup is already a string, can't you just do the following and avoid a redundant call to .ToString()?

switch(strGroup)
