string.Format fails at runtime with array of integers

Question

Consider string.Format() whose parameters are a string and, among others in the overload list, an object[] or many objects.

This statement

Answer 1

I think the concept you are having an issue with is why int[] isn't cast to object[]. Here's an example that shows why that would be bad

int[] myInts = new int[]{8,9};
object[] myObjs = (object[])myInts;
myObjs[0] = new object();

The problem is that we just added an object into a int array.

So what happens in your code is that myInts is cast to object and you don't have a second argument to fill in the {1}
