Switch statement with static fields

Question

Suppose I have a bunch of static fields and I want to use them in switch:

public static string PID_1 = \"12\";
public static string PID_2 = \"13\";
public st         


        

Answer 1

The canonical way to approach this -- if your static fields are not actually constants -- is to use a Dictionary<Something, Action>:

static Dictionary<string, Action> switchReplacement = 
    new Dictionary<string, Action>() {
        { PID_1, action1 }, 
        { PID_2, action2 }, 
        { PID_3, action3 }};

// ... Where action1, action2, and action3 are static methods with no arguments

// Later, instead of switch, you simply call
switchReplacement[pid].Invoke();
