Using .StartsWith in a Switch statement?

Question

I'm working on a Switch statement and with two of the conditions I need to see if the values start with a specific value. The Switch statement does like this. The error says "cannot covert type bool to string".

Anyone know if I can use the StartsWith in a Switch or do I need to use If...Else statements?

switch(subArea)             {                 case "4100":                 case "4101":                 case "4102":                 case "4200":                     return "ABC";                 case "600A":                     return "XWZ";                 case subArea.StartsWith("3*"):                 case subArea.StartsWith("03*"):                     return "123";                 default:                     return "ABCXYZ123";             } 

Answer 1

Since C# 7 you can do the following:

switch(subArea) {     case "4100":     case "4101":     case "4102":     case "4200":        return "ABC";     case "600A":        return "XWZ";     case string s when s.StartsWith("3*"):        return "123";     case string s when s.StartsWith("03*"):        return "123";     default:        return "ABCXYZ123"; } 

Answer 2

EDIT: If you are using C# >= 7, take a look at this answer first.

You are switching a String, and subArea.StartsWith() returns a Boolean, that's why you can't do it. I suggest you do it like this:

if (subArea.StartsWith("3*") || subArea.StartsWith("03*"))     return "123";  switch(subArea) {     case "4100":     case "4101":     case "4102":     case "4200":         return "ABC";     case "600A":         return "XWZ";     default:         return "ABCXYZ123"; } 

The result will be the same.
