Com application Summary (3/3) COM component in C #

Due to the wide application of. net, the interoperability problem between C # and COM is often encountered in daily work. To be more complete, This article summarizes the situation of C # Processing com as follows:

In C #, It is very convenient to interoperate with COM, specifically as follows:

No Pia	C #4.0 dynamic features introduced Guid ID; Id = new GUID ("D7D0B2E8-1795-4E23-96BF-F07EC28FB44C "); Dynamic complug = activator. createinstance (type. gettypefromclsid (ID )); String T = "DLR", R; Complug. dowork (T, out R ); Console. writeline (R );

The following is a comparison of C # different versions of office operations
