Failed to load file or assembly "oracle.dataaccess, version=2.112.1.0, culture=neutral, publickeytoken=89b483f429c47342"

If the Oracle version of this machine is a 64-bit system, the following error is reported in the time the Oracle data is called:

"Failed to load file or assembly" oracle.dataaccess, version=2.112.1.0, culture=neutral, publickeytoken=89b483f429c47342 "or one of its dependencies. An attempt was made to load an improperly formatted program "

The main reason is that the server is different from the native Oracle version.

Solution:

1. Replace the project's reference to this DLL with a 64-bit oracle.dataaccess

2. Modify the project build target, select "Build" "Target platform" as X64

Debug again, OK
