Select Case Statement in C# / C-sharp

Switch Case Statement in C# (.NET)

Here is an example of Select Case like construct using C#:

private string ShirtSizes(int ShirtSize) 

{ 

switch (ShirtSize) 

{ 

case 36: 

return "Small"; 

case 38: 

return "Medium"; 

case 40: 

return "Large"; 

case 42: 

return "Extra Large"; 

case 44: 

return "XXL"; 

default: 

return "Free Size"; 

} 

}  

Fall-Thru in Switch Case Statement in C#(Csharp)

Fall through can be achieved as follows:

switch (ShirtSize) 

{ 

case 34: 

case 35: 

case 36: 

return "Small"; 

case 38: 

return "Medium";  ...   

The Switch construct requires jump statements like GoTo or Break to transfer control outside the loop. Else it will throw an Error Control cannot fall through from one case label ### to another

To avoid this use break / goto statements. On the other hand if you use more than one jump statement for a case - like the one shown below - you will get Unreachable code detected warning

case 38: 

return "Medium"; 

break;
