Register the. NET component as a COM Component

Switch to the MS-DOS command line and run:
C: "> regasm classlibrary1.dll/regfile: classlibrary1.reg
The above command line registers our. NET Component and generates a backup registry file. We will remember that the command used to register COM components Under Win9x/NT/2000 is:
Regsvr32 C: "test. dll

In. net. the above regasm command is required for the net component. It is worth noting that this method is only for the COM component to call ,. net itself does not need to be registered to call each other's components!
