C# Variable Initialization Question

Question

Is there any difference on whether I initialize an integer variable like:

int i = 0;
int i;

Does the compiler or CLR treat this as the same

Answer 1

These are only equivalent for fields (class variables). Fields are automatically assigned the default values when the class is initialized. Within a method or property, the unassigned variable remains unassigned and will cause a compiler error if you try to access it's value.
