Question

I am attempting following code to create multiple instances of a class at run-time and want to initialize also, but it is giving error:

A local variable named ‘inum’ cannot be declared in this scope because
it would give a different meaning to ‘inum’, which is already used in
a ‘parent or current’ scope to denote something else.

public class MyClass
{
    static int i=0;

    class A
    {
        public A()
        { 

        }
    }

    public static void Run()
    {
        string inum = "i";
        for (int j=1;j<=5;j++)
        {
            inum = inum + j.ToString();
            //Initialize Instance
            A inum = new A();
        }
    }
}

You appear to be trying to use variable names “dynamically”. That doesn’t work in C#, and you should change how you think about variables. If you want to create several instances, declare an array:

public class MyClass
{
    static A[] instances;

    class A
    {
        public A()
        { 

        }
    }

    public static void Run()
    {
        instances = new A[5];
        for (int j=0;j<5;j++)
        {
            instances[j] = new A();
        }
    }
}
