C#元帅typedef char T_STRING [MAX_STRING_SIZE] [英] C# Marshal typedef char T_STRING[MAX_STRING_SIZE]

问题描述

如何指挥:

[C++]
#define MAX_STRING_SIZE 255
typedef char T_STRING[MAX_STRING_SIZE];
typedef struct
{
    unsigned long m_ID;
    T_STRING m_name;
} Result;

在C#中?

当前我正在执行此操作(但它不起作用):

Currently I am doing this (but it does not work):

[C#]
[StructLayout(LayoutKind.Sequential)]
public struct Result
{
    public uint m_ID;

    [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 255)]
    public char[] m_name;
}

我尝试使用IntPtr代替char []，但结果不尽相同.有和没有[MarshalAs(...)].

I have tried to use a IntPtr instead of char[] with equal non-working result. Both with and without [MarshalAs(...)].

推荐答案

将其编组为:

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
public struct Result
{
    public uint m_ID;

    [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 255)]
    public string m_name;
}
