Question

I have a class Foo in C# that has a string name and I want each one to have a unique name. What I wanted to do is get the name from creating a static int variable and then assigning it to a local instance int variable to which I add to the end of the string. This does not work though, how would I be able to get my desired result.

class Foo
{
    static int count = 0;
    int fooNum;
    string name;

    public Foo
    {
        ++count;
        fooNum = count;
        name = "Foo" + fooNum;
        Console.WriteLine(name);
    }
}

int main()
{
   for(int i = 0; i < 5; i++)
   {
      Foo test = new Foo();
   }
}

Actual Output:
Foo5
Foo5
Foo5
Foo5
Foo5

Desired Output:
Foo0
Foo1
Foo2
Foo3
Foo4

Any help would be greatly appreciated

Thanks

Your code doesn’t compile. Correcting it to:

class Foo
{
    static int count = 0;
    int fooNum;
    string name;

    public Foo()
    {
        ++count;
        fooNum = count;
        name = "Foo" + fooNum;
        Console.WriteLine(name);
    }
}

static void Main(string[] args)
{
    for (int i = 0; i < 5; i++)
    {
        Foo test = new Foo();
    }
}

makes it compile and work like a charm. It prints

Foo1
Foo2
Foo3
Foo4
Foo5
