DotNet - What is int *?

Hi, I was looking at some source code for the library, and I saw this byte* , what is the star at the end of ?, and not just with the class byte, but also with some variables like

 var1 = *var3 - *var2; 

early

Answer 1

This is a pointer (in bytes).

Answer 2

When * used for a data type, it is a pointer to that type. byte* - pointer to byte.

When used in a variable, it will dereference the pointer. The value of var3 is a pointer, and the value of *var3 is the byte (or any other type) that the pointer points to.

Answer 3

I am sure its unsafe code.
