Problem with Out

[ante75]

Hello everyone I chiamao Alex, I'm trying to use WrapperClient but I have a problem I get an error by doing this:

private delegate Int32 H264_DVR_Login(string sDVRIP, ushort wDVRPort, string sUserName, string sPassword, out H264_DVR_DEVICEINFO lpDeviceInfo, out int error, SocketStyle socketstyle);

static public Int32 WrapperH264_DVR_Login(string sDVRIP, ushort wDVRPort, string sUserName, string sPassword, out H264_DVR_DEVICEINFO lpDeviceInfo2, out int error, SocketStyle socketstyle)
 {
    using (var client = new WrapperClient("NetSdk.dll"))
     {
       error = 0;
       H264_DVR_DEVICEINFO lpDeviceInfo = new H264_DVR_DEVICEINFO();
       Int32 x = (Int32)client.Invoke<H264_DVR_Login>("H264_DVR_Login", new object[] { sDVRIP, 
                       wDVRPort, sUserName, sPassword, lpDeviceInfo, error, socketstyle });
       lpDeviceInfo2 = lpDeviceInfo;
       return x;
      }
}

ERROR: System.Runtime.Serialization.SerializationException: 'Il tipo 'TestVideo.H264_DVR_DEVICEINFO' nell'assembly 'TestVideo, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' non è contrassegnato come serializzabile.'

THE PROBLEM IS IN Out H264_DVR_DEVICEINFO lpDeviceInfo ???

who can help me? thank you all

From the error message I guess your class H264_DVR_DEVICEINFO needs a [Serializable] attribute on top. The error message is not related to out parameters.

Kind Regards, Franz

Thanks for the help, I added [Serializable]
Now the mistake became this System.Runtime.Serialization.SerializationException: 'End of stream reached before the analysis is complete.'

Hi, can you paste some details of the Exception (stacktrace, message, etc)?

[ante75]

I copied the exception details, can you understand something?

Looking for the HResult code with this link tells me that A mismatch has occurred between the runtime type of the array and the sub type recorded in the metadata.

So can you check all your type definitions for your delegate match the function in your dll?

[ante75]

this is the original call:

H264_DVR_DEVICEINFO dvrdevInfo = new H264_DVR_DEVICEINFO(); int nError; int nLoginID = XMSDK.H264_DVR_Login(ip, port, User, Password, out dvrdevInfo, out nError, SocketStyle.TCPSOCKET);

I can not understand what it refers to the error COR_E_SERIALIZATION 0x8013150c A mismatch has occurred between the runtime type of the array and the sub type recorded in the metadata.

[zalintyre]

Have you got a proper API description of your desired function and its parameters at hand?

[ante75]

I try to find some information

For the moment thank you
