Add a reference to jmail in Visual Studio.

Problem: When a jmail reference is added, a non-COM component is prompted and cannot be added.

After a long time, I finally added it. I recorded it and forgot it later.

1. Download jmail. dll;

Tlbimp.exe for conversion

1. Open a command prompt under Visual Studio Tools

2. Enter tlbimp.exe D: \ jmail. dll/out: D: \ jmail. dll/namespace: jmail, and press enter to convert it;

3. Add a reference to the newly generated jmail. dll.

Iii. the. NET class library version will be used during conversion. For example, vs2005 uses. NET 2.0 and vs2012 uses version 4.0. If only vs2012 is installed, you do not know how to manually set the version.
