hi,
you are getting this error because in a variable you are assigning c, but c dont have any value, that is reason you have to reverse this the correct code is as below
static void Main(string[] args)
{
int a, b;
int c;
Console.Write("enter 2 values");
a = Console.Read();
b = Console.Read();
c=a;// assign a value to c
a = b; // assign b value to a
b =c;  //assign c value to b that is you are assigning a value to b
Console.Write(a);
Console.Write(b);
}

I guess you are trying to swap 2 numbers and there is some mistake in your logic, here is the logic,
static void Main(string[] args)
{
int a, b;
int c;
Console.Write("enter 2 values");
a = Console.Read();
b = Console.Read();
c = a;
a = b;
b = c;
Console.Write(a);
Console.Write(b);
}
Hope it helps :)
