Let's take a look at JavaScript (the basic type and the simple type below are a meaning):There are two types of variables in JavaScript, one of which is the basic type, a total of five, with null, Bollean, undefined, number, and string. A primitive

Many DLLs are written in C and C + +, so what if C # wants to invoke a function in a DLL, especially if one of the DLL functions is a function pointer, that is, how do you do it in C # with a back-up function? The return function in C has a special
