Where does DLLImport look for unmanaged DLLs?

问题

A quick question: When declaring the DLLImport Attribute in .Net, where does the runtime look to resolve that DLL dependency? Would I have to dump the DLL and all of its dependencies in the bin folder?

回答1:

I think it is working like LoadLibrary.

Maybe Windows path searching in LoadLibrary with manifest will be helpfull.

Edit Dynamic-Link Library Search Order is probably what you want.

回答2:

Generally, you'd expect it to look at whatever's defined in the user's Path.

To find out what this contains, from a command prompt, type echo %PATH% [Enter]
