问题
I'm calling an unmanaged dll from my managed c# code and wanted to check I'm calling the right version.
The code I'm trying to load the assembly (to then get the resource file and then get the version) is:
cur_version = Assembly.LoadFile("X:\Workspace\yreceipts_pos\yRprintProcessor\Debug\yRprintProcessor.dll");
It's failing because of this error:
The module was expected to contain an assembly manifest. (Exception from HRESULT: 0x80131018)
Does anyone know how to get around this or have a better way to check the version of an unmanaged dll from managed c# code?
Thanks in advance, Richard

As stated by logicnp; the Assembly.Load is for managed assemblies only. To determine the version of any version-ed file you can use System.Diagnostics.FileVersionInfo.GetVersionInfo(filename) and to load and call unmanaged procedures in DLLs you can refer to these articles:

Good luck...

The reason it fails is becuase you cannot use Assembly.Load to load unmanaged dlls. See the link suggested by David Brown.
