编组C数组在C＃ [英] Marshaling C arrays in C#

问题描述

  

可能重复：
  编组C结构的C＃

实际的C结构：

  typedef结构的过程
{
  字符code [8]。
}程序;

typedef结构p45_cldxed24
{
  过程p45_cldxed [8];
} p45_cldxed24;
 

什么是等价的C＃结构p45_cldxed24？具体来说，您将如何封送数组？

检查了这一点，一旦

这是正确的？

  [StructLayout（LayoutKind.Sequential，字符集= CharSet.Ansi）
结构p45_cldxed24
{
    [MarshalAsAttribute（UnmanagedType.LPArray，ArraySubType = UnmanagedType.Struct，SizeConst = 8，SizeParamIndex = 0）]
    程序[] p45_cldxed;
}
 

解决方案

我相信，code将如下：

  [StructLayout（LayoutKind.Sequential，字符集= CharSet.Ansi）
结构p45_cldxed24
{
    [的MarshalAs（UnmanagedType.ByValArray，SizeConst = 8）]
    程序[] p45_cldxed;
}
 

这里的关键是，的MarshalAs 属性。

Actual C structures:

typedef struct procedure
{
  char code[8];
}procedure;

typedef struct p45_cldxed24
{
  procedure p45_cldxed[8];
}p45_cldxed24;

What would be the equivalent C# structure for p45_cldxed24? Specifically, how would you marshal the array?

check this out once

Is this correct?

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
struct p45_cldxed24
{
    [MarshalAsAttribute(UnmanagedType.LPArray, ArraySubType=UnmanagedType.Struct,SizeConst = 8,SizeParamIndex=0)]
    procedure[] p45_cldxed;
}

解决方案

I believe the code would be as follows:

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
struct p45_cldxed24
{
    [MarshalAs(UnmanagedType.ByValArray, SizeConst = 8)]
    procedure[] p45_cldxed;
}

The key here is that MarshalAs attribute.
