C#使用Dllmport来调用dephi的dll

一般是用非托管的
    具体形式如下：[DllImport（"WZFSE.dll", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.StdCall）]
    下面紧接着他的申明函数
    public static extern void InitDll（IntPtr handle, bool methodAddress）；
    申明一个函数就要引用下他的dll
    IntPtr这个类型可以申明为其他语言的句柄，指针等。
    若要实现其他语言类似C++的函数指针形式这时我们考虑用C#的委托来实现
    将dephi的窗体签入到自己的C#系统里还有一点比较重要，我们是调用dephi的窗体，此时显示在我们C#窗体中会有dephi的窗体
    这时我们怎么办呢怎么去除dephi中的窗体呢这时我们就需要用API函数了 API函数在dephi有 C#中也有
    在C#中是这么引用的 [DllImport（"user32.dll", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.StdCall）]
    public static extern void MoveWindow（IntPtr handler, int x, int y, int width, int height, bool repaint）；
    下面插入一个类这里面包含了怎么引用dephi的dll 以及怎么申明
    代码
    1 public class CompliancePlatDLL
    2     {
    3         public static string strPath = "";

    9         [DllImport（"WZFSE.dll", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.StdCall）]
    10         public static extern void InitDll（IntPtr handle, bool methodAddress）；
    11         /// <summary>
