Multi-variable switch statement in C#

Question

I would like use a switch statement which takes several variables and looks like this:

switch (intVal1, strVal2, boolVal3)
{
   case 1, \"hello\", false:
            


        

Answer 1

You can do this in C# 7 and higher with the when keyword:

switch (intVal1)
{
    case 1 when strVal2 == "hello" && boolVal3 == false:
        break;
    case 2 when strVal2 == "world" && boolVal3 == false:
        break;
    case 2 when strVal2 == "hello" && boolVal3 == false:
        break;
}
