问题描述
我想从C#PInvoke用VB6编写的函数。调用DLL的VB6代码声明如下:
I want to PInvoke a function written in VB6 from C#. The VB6 code that calls the DLL is declared like this:
Declare Function ApplyNNet Lib " location of the DLL file" (MyNNetType As String, MyAddress As String, MyInput() As Double) As Variant
My C#版本如下所示: *
My C# version looks like this:*
[DllImport("NNetApply.dll")]
public static extern object ApplyNNet(string type, string add, double[] data);
我这样称呼函数:
I call the function like this:
object P_ = ApplyNNet("Back Prop", address,data);
使用此声明我收到PInvoke错误:
With this declaration I receive a PInvoke error:
PInvoke restriction: cannot return variants.
