Examples

This example shows how to get a pointer to an interface and marshal the pointer into an actual interface object.

IVsLanguageService GetLanguageService()  
{  
    IVsLanguageService pLanguageService = null;  
    IntPtr ptr = IntPtr.Zero;  
    GetSite(typeof(IVsLanguageService),ptr);  
    if (ptr != IntPtr.Zero)  
    {  
        pLanguageService = (IVsLanguageService)Marshal.GetObjectForIUnknown(ptr);  
    }  
    return pLanguageService;  

}
