在多案例陈述中检查案例

Question

Consider following case statement

Case 'A':
     break;
Case 'B':
Case 'C':
     // some logic
     int i = 0;

     // here I need i =5 (if case id 'B')  and i=10 (if case is 'C')

     // Rest of the logic is same
     break;

I know I can achieve this by writing seperate case for 'B' and 'C' and writing rest of the logic in a seperate function and call that function in 'B' and 'C' case.

But is there any way, I can check the case in Case statement only ... as follows

Case 'B':
Case 'C':
     // Can I check here
     // if (case == 'B')
     //      i = 5;
     // if (case == 'C')
     //      i = 10;
     // Rest of the logic

Answer 1

I tried the following which worked without any problems:

switch (a)
{
    case 'A':
        Console.WriteLine("Es ist ein 'A'.");
        break;
    case 'B':
    case 'C':
        if (a == 'B')
            Console.WriteLine("Es ist ein 'B'.");
        if (a == 'C')
            Console.WriteLine("Es ist ein 'C'.");
        break;
}

But if you're just checking if it's 'B' or 'C', I would suggest writing two separate cases.

Put your //Rest of Logic inside a new method, and do separate test cases for a neater code:

private void DoSomething(int i)
{
    //Rest of Logic
}

public void SwitchMethod(char input)
{
    int i = 0;
    Switch (input)
    {
        case 'A': 
            break;
        case 'B':
            i = 5;
            DoSomething(i);
            break;
        case 'C':
            i = 10;
            DoSomething(i);
            break;
    }
}
