IF sucks ?

IF sucks ?

Hi,
I have this problem with the if command
[code:1]if(value == 1)
{
Item item = new Item( 0x203C );
}
if(value == 2)
{
Item item = new Item( 0x203D );
}
[/code:1]
and so on

The problem is:
[code:1]A local Variable named 'item' cannot be declared in this scope because it would give a different meaning to 'item', which is already used in a 'parent or current' scope to denote something else[/code:1]

Anybody knows what I can do ?

Doesn't C# have a Case argument? If it does that would be a much cleaner way to code it... */me goes to the manual to check*

 

[p3nt4x0r]

you have to name the item something like MyItem, otherwise it ist taken as type identifier..

There is a select statement!
[code:1]
switch ( blabla ) {
case 1:
break;
case 2:
break;
}
[/code:1]

thnx that works now
but now i have a new problem:

I have a function:
[code:1]
public void MyFunction( int thisvar, NetState state )
{
blablubb
}
[/code:1]

[code:1]
switch( Value )
{
case 2: { int newvar = 5; }
case 3: { int newvar = 23; }
}
MyFunction( newvar, from );
[/code:1]

From is defendied a bit above, thats no problem
But with the newvar he got say that 'newvar' is not defenied
What can I do here ?

I don't have a compiler on this machine to check the syntax but you should be able to do this.

[code:1]
int newvar;
switch( Value )
{
case 2: { newvar = 5; }
case 3: { newvar = 23; }
}
MyFunction( newvar, from );
[/code:1]

Your first problem dont work because de local varible exist only in the scope of your { }

You can't do:

...
if ( GetBlabla() )
{
int iWrong = 20;
}
return iWrong;
...

Because iWrong exist only in between the { and }

so you should do

...
int iRight = 0;
if (GetBlabla() )
{
iRight = 20
}
returm iRight;
...

Its the same thing in "case", you must not declare local variable inside the { and } (execpt if you only use them there.
