DllNotFoundException uses the HRESULT COR_E_DLLNOTFOUND, which has the value 0x80131524.

For a list of initial property values for an instance of DllNotFoundException, see the DllNotFoundException constructors.

The DllNotFoundException is thrown when a dynamic link library defined by the System.Runtime.InteropServices.DllImportAttribute attribute or a comparable language construct, such as the Visual Basic Declare statement, cannot be found. It is not thrown when the common language runtime is unable to load a .NET Framework assembly.

Note that the DllImportAttribute can specify the path to the directory in which the DLL resides. If a path is not specified, Windows uses the search order described in Dynamic-Link Library Search Order.
