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 G

Answer 1

with c#7 you can now use switch with Pattern Matching for this purpose.

switch (cboRole)
{
    case var r when (r == new Guid("532E8EED-9E72-42E0-871E-36470C1AE327")):
        param1 = "4E08BA7C-E81F-40AE-92F0-DF33A98DD0BB";
        MessageBox.Show("It's working");
        break;
    case var r when (r == new Guid("FA7637E9-A9E4-4D57-A59B-80615424D27F")):
        param1 = "E540C382-F22C-4FE2-9068-1E10AA8DD076";
        break;
    case var r when (r == new Guid("2734CCD9-93E6-4A86-8B83-5EA9E62FA921")):
        param1 = "8A54F8D5-5B74-4B3F-A29A-D423AA8DD02E";
        break;
    default:
        MessageBox.Show("Not Working");
        break;
}

This also works if you have defined static readonly new Guid"..") variables.

Answer 2

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.
