从C#传递到C代码的结构数组

using System;
using System.Runtime.InteropServices;

// 定义C#结构体
[StructLayout(LayoutKind.Sequential)]
public struct MyStruct
{
    public int intValue;
    public float floatValue;
    public char charValue;
}

class Program
{
    // 声明C语言函数
    [DllImport("mylib.dll")]
    public static extern void ProcessStructArray(MyStruct[] array, int length);

    static void Main(string[] args)
    {
        // 创建结构体数组
        MyStruct[] array = new MyStruct[3];
        array[0].intValue = 1;
        array[0].floatValue = 1.1f;
        array[0].charValue = 'A';
        array[1].intValue = 2;
        array[1].floatValue = 2.2f;
        array[1].charValue = 'B';
        array[2].intValue = 3;
        array[2].floatValue = 3.3f;
        array[2].charValue = 'C';

        // 调用C语言函数处理结构数组
        ProcessStructArray(array, array.Length);

        Console.WriteLine("C# program finished.");
    }
