在C#中引用LabView Dll，但是發生PInvoke簽章錯誤

LabVIEW
1

環境: windows 10 + visual studio 2017 C#
LavView Dll: LabView 2014 輸出的DLL

DLL Prototype :
abcdR

到C#中的函數引用:
[DllImport(“ReadEEPROMDataLib.dll”)]
unsafe public extern static Int32 ReadEEPROMData([MarshalAs(UnmanagedType.LPWStr)] string Interface, float* R, float* d, float* c, float* b, float* a, Int32* ReadTimes, [MarshalAs(UnmanagedType.LPWStr)] string TrackingNumber15Digits, Int32 len);

實際使用函數:

         unsafe
        {
            string InterFace = "CAN1";
            string TrackingNumber15Digits = "000000000000000";

            float R, D, C, B, A =0;
            float* r = &R;
            float* d = &D;
            float* c = &C;
            float* b = &B;
            float* a = &A;

            int Readtime = 50;
            int* RT = &Readtime;

            int len = 15;
            int re = ReadEEPROMData(InterFace, r, d, c, b, a, RT,TrackingNumber15Digits, len);

        }

發生的錯誤如下:

請問，我要如何正確地引用 來自 LabVIEW的DLL?

謝謝
