Switch Problem

[Maarten-tutoworld]

I have the following code:

int a = 0;
switch (A)
{
case 0:
{
string lang001 = "Welkom";
string lang002 = "Tot ziens";
}
break;

case 1:
{
string lang001 = "Welcome";
string lang002 = "Goodbye";
}
break;
default:
{
string lang001 = "Welcome";
}
break;

It is the intention that I somewhere else in my programming code lang001 place and then depending on whether a 0 or 1 is a specific language is displayed.
Only when I'm somewhere in the code lang001 drop I get the message that this is never defined

Welcome to the forum
You should not that C# is a case-sensitive language which means a variable named "a" is not same as "A". In your code you are defining int a = 0 however in the switch statement you are checking for "A". If you replace switch (A) with switch(a), it should work properly.

You should also remember to use proper names for the variables, that way it will be easier to maintain your code in the long run. Make it a habit now and you will reap number of benefits in your career later.

Also when you post code here in the forums, you should use code tags.

That is because you define lang001 inside the switch scope, you should move the defenition outside the switch block and set its value inside the switch block:

int a = 0;
string lang001;
string lang002;
switch (a)
{
    case 0:
    {
	lang001 = "Welkom";
        lang002 = "Tot ziens";
    }
    break;

    case 1:
    {
        lang001 = "Welcome";
        lang002 = "Goodbye";
    }
    break;
    
    default:
    {
        lang001 = "Welcome";
    }
    break;
}

thank you for your help, now I have what you see below but still I don't get the switch in the same scope.. can't understand what I am doing wrong.

Why don't you use a standard method of translating your application instead of a home-brew method which is less likely to work and a hell of a lot harder to maintain?

accidently forgot to actually post my code with the reply, I apologize for that.
(message was to long, i've cut out some code, where you see [...] there is code.
Found a solution to show all the code, you can find it here: http://cl1p.net/gpeditalternative/

Again, thanks in advance

Well, I did search for ways to translate my application with a somewhat standard method but the methods I found were beyond my knowledge, I didn't understand the code that they used. And it doesn't seem smart to use certain code if I don't even know how it works and if the code fits my needs. If you have a page for me which shows how to use the standard code for localization of my application I would be very glad.
