How to use a switch statement with Guid?

Question

In the following C# code, cboRole returns a Guid. I'm then trying to use it in a switch statement to do some actions. cboRole can return only 4 different Guid so I think a switch is a good option for me. The thing is that all the case are ignored and I always get the default action. When I debug I clearly see that cboRole return a value like in the following printscreen. What is the correct way to "compare" Guids in a C# switch statement Code: ``` if (!cboRole.IsNull) { switch (cboRole.EditValue.ToStringEx()) { case "532E8EED-9E72-42E0-871E-36470C1AE327": param1 = "4E08BA7C-E81F-40AE-92F0-DF33A98DD0BB"; MessageBox.Show("It's working"); break; case "FA7637E9-A9E4-4D57-A59B-80615424D27F": param1 = "E540C382-F22C-4FE2-9068-1E10AA8DD076"; break; case "2734CCD9-93E6-4A86-8B83-5EA9E62FA921": param1 = "8A54F8D5-5B74-4B3F-A29A-D423AA8DD02E"; break; default: MessageBox.Show("Not Working"); break; } ```

Accepted Answer

Your switch statements are in upper-case while your `ToStringEx()` returns the `Guid` in lower-case.

You can use

```
switch (cboRole.EditValue.ToStringEx().ToUpper())
```

or modify your `case` statements.
