0x80000000 == 2147483648 in C # but not in VB.NET

Question

In C #:

0x80000000==2147483648 //outputs True

In VB.NET:

&H80000000=2147483648 'outputs False

How is this possible?

Answer 1

This is due to the story behind the languages.

C # always supports unsigned integers. The value you use is too large for int, so the compiler chooses the next type that can correctly represent the value. This is uint for both.
