如何我可以转换ptrStructo byte []吗？



请帮帮我

how can i convert ptrStructo byte[]?

推荐答案

为什么你要转换？只需创建自己的类，如下所示，并将其用于您的应用。

Why you have to convert ? Just create your own class is as below and use it for your app.

public class ClassName
   {
    public byte [] a { get; set; }
    public int b { get; set; }
   }

我希望这会对你有所帮助。

I hope this will help to you.

如果您需要将一个托管结构传递给非托管代码，您可以像在以下示例中那样进行（取自：MSDN [ ^ ]）：

If you need to pass one managed structure to unmanaged code you could do it like in the foollowing example (taken from: MSDN[^]):

using System.Runtime.InteropServices;

[StructLayout(LayoutKind.Sequential)]
public struct Point {
    public int x;
    public int y;
}   

[StructLayout(LayoutKind.Explicit)]
public struct Rect {
    [FieldOffset(0)] public int left;
    [FieldOffset(4)] public int top;
    [FieldOffset(8)] public int right;
    [FieldOffset(12)] public int bottom;
}   

class Win32API {
    [DllImport("User32.dll")]
    public static extern bool PtInRect(ref Rect r, Point p);
}

如果你想将数组传递给非托管函数，这也有帮助： MSDN [ ^ ]



用于从Windows API中使用函数pinvoke.net/ [ ^ ]有非常有用的资源和您可以使用的示例代码。

If you want to pass the array to the unmanaged function this could also help: MSDN[^]

For consuming functions from windows APIs pinvoke.net/[^] has very usefull resources and sample code you could use.
