Section 2nd describes how to provide the Add function interface using the static Link Library. Next we will look at how to use the dynamic link library to implement the Add function with the same function.
For example

Many times, we need to compile the. cs file individually into a. dll file, which requires the CSC command to compile the. cs file into a. dll dynamic link library file. The specific steps are as follows:
Open the Command Window-> enter CMD to the console->CD c:windowsmicrosoft.netframeworkv1.1.4322
Go to the directory where the vs.net is installed-> execute the CSC command csc/target:library file.cs-> A.
Exporting from a DLL using a DEF file
A module definition (. def) file is a text file that contains one or more module statements that describe various attributes of a DLL. If you do not use the __declspec (dllexport) keyword to export a DLL's functions, the DLL requires a. def file.
The. def file must contain at least the following module definition statements:

I. Preface
Since Microsoft launched a 16-bit Windows operating system, every version of Windows operating system is dependent on functions and data in the dynamic link library (DLL, in fact, almost all content in Windows is represented by DLL in one or another form, for example, the displayed fonts and icons are stored in the gdi dll, the Windows desktop is d
First, DLL Overview:
The dynamic-link library (Dynamic-link Library), referred to as a DLL, is a very important component of Windows programming. There are many advantages to using DLLs:
(1) A dynamic connection using a DLL is not a copy of the library code, only the entry points and interfaces for functions are recorded in the program, the library code is load
