Open the project's properties, click the signature assembly on the left, and select the HelloWorld.snk file just created in Choose a strong name key file:
4. Create a class library and compile it into a dll
The copy code code is as follows:
Namespace HelloWorld
{
//[COM Visible(true)]// Or check "assemblycom-visible" in the application-assembly _ information dialog box;
Hello, open class
{
Common string writing ()
{
Return "hello world";

Enter the dll folder and enter:
The copy code code is as follows:
Regasm HelloWorld.dll < input >
At this time. The. net assembly of this. Dll will beCome a standard Com component, but it can't be used yet, so it must be turned into a global com component.
Add an assembly to the global assembly cache
Enter the prompt window and enter:
The copy code code is as follows:
gacutil/I hello world . dll & lt； Enter >
