它编译没有任何错误。

解决方案

This may or may not be the issue that you are facing, but I had exactly the same issue and I found that the dll I was loading was an old file.

Rebuild the project and then actually go into the directory that the dll is in and check that it has a creation/modification time that is current.

It's very easy, for example, to create:

my_project/
my_project/domain/
my_project/unit-tests/ (removed but not deleted on the HD, not visible in studio)
my_project/domain/unit-tests/ (visible as MyProject.UnitTests)

If you then load the dll in my_project/unit-tests/ you may not be loading the dll you just built.

Try also file -> save as while editing a test class, and see what actual directory it is being saved into, and check that the dll you are loading is from the same path.
