代码如下:但总是提示:方法类型签名与PIvoke不兼容
这里 返回值mydb是一个结构体,输入参数为数组指针:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;//引入dll文件的函数
namespace dll文件链接
{
class Program
{
[DllImport("EMatrix.dll", EntryPoint = "EnergySolver", CallingConvention = CallingConvention.Cdecl)]
private static extern mydb EnergySolver(IntPtr ZUCHNEG);//引入dll中写好的函数
[StructLayout(LayoutKind.Sequential, Pack = 1)]
public struct mydb
{
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 100)]
public double[] x;//Y坐标的值,单位U(mm/s),该数组从1开始计数
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 20)]
public double [] y;//X坐标的值,单位P(MPa),该数组从1开始计数
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 20*4)]
public double[]a;//X坐标的值,单位P(MPa),该数组从1开始计数
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 100)]
public double[] b;//X坐标的值,单位P(MPa),该数组从1开始计数
}
static void Main(string[] args)
{
double[] m_PeiFang1 = new double[] { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };
m_PeiFang1[0] = 13.731882598335664;
m_PeiFang1[1] = 89.175685804764413;
m_PeiFang1[2] = 13.731882598335664;
m_PeiFang1[3] = 2.2614300711402282;
m_PeiFang1[4] = -3438.4000000000001;
m_PeiFang1[5] = 450.00000000000000;
IntPtr ptr = Marshal.AllocHGlobal(m_PeiFang1.Length * Marshal.SizeOf(typeof(double)));//分配内存
mydb a = EnergySolver( ptr);
Console.ReadKey();
}
}
