Note: 1. This operation COM must first reference a com Interactive Operation RWC. First, add the reference diskquotatypelibrary.

2. Add it to the top of ASP. NET.

3. If you want to operate COM in ASP. NET, you must have sufficient permissions, but ASP. NET is insufficient. Therefore, you must add this line to Web. config. Of course, you can also use other methods to grant permissions.

4. OK.
