How do I load a typelib to parse it in C#?

Question

In unmanaged code I can use `LoadTypeLib()` to obtain an `ITypeLib*` pointer and use that to look into the typelib to find what interfaces it contains. There is `System.Runtime.InteropServices.ComTypes.ITypeLib` interface in C# but I can't find an equivalent to `LoadTypeLib()` function. How do I load a typelib and obtain an `ITypeLib` reference in C#?

Accepted Answer

Copied straight from System.Design.NativeMethods, Reflector is useful:

```
[DllImport("oleaut32.dll", PreserveSig=false)]
public static extern ITypeLib LoadTypeLib([In, MarshalAs(UnmanagedType.LPWStr)] string typelib);
```
