C# calling Hikvision CHCNetSDK failed to load the type "WIFI_AUTH_PARAM" from the assembly because it contains an object field at offset 0...

Problem Description:

C# fails to load the type "WIFI_AUTH_PARAM" from the assembly when calling Hikvision CHCNetSDK because it contains an object field at offset 0 that has been incorrectly aligned or overlapped by a non-object field.

solution:

1. It is necessary to change the LayoutKind.Explicit of the entire file interface body header to LayoutKind.Auto, as follows:

    [StructLayoutAttribute(LayoutKind.Auto)]
    public struct WIFI_AUTH_PARAM
    {
        [FieldOffset(0)]
        public UNION_EAP_TTLS EAP_TTLS;//WPA-enterprise/WPA2-enterpris模式适用
               
               
        public UNION_EAP_PEAP EAP_PEAP; //WPA-enterprise/WPA2-enterpris模式适用
   
        public UNION_EAP_TLS EAP_TLS; 
    }

2.  Delete all [FieldOffset(0)], as follows

   [StructLayoutAttribute(LayoutKind.Auto)]
   public struct WIFI_AUTH_PARAM
   {
               
      public UNION_EAP_TTLS EAP_TTLS;//WPA-enterprise/WPA2-enterpris模式适用
               
               
      public UNION_EAP_PEAP EAP_PEAP; //WPA-enterprise/WPA2-enterpris模式适用
   
      public UNION_EAP_TLS EAP_TLS; 
   }

   Normal use after modification.
