C#中如何定义这样的结构

[zhaojin1975]

我要用到C++编写的动态库，参数中有结构，如下所示：
#pragma pack(1)
typedef struct
{
char TranCode[3];
char TranDate[9];
char TranTime[7];
char Operator[4];
}test;
#pragma pack()

请问在C#中如何定义这样的结构？
注意：是紧凑格式的(pack)，结构总长度3+9+7+4=23

[yuan731]

public struct test
{
public char TranCode[3];
public char TranDate[9];
public char TranTime[7];
public char Operator[4];
}

[yuan731]

public struct test
{
public string TranCode;
public string TranDate;
public string TranTime;
public string Operator;
}

还有长度。。。
[MarshalAs(UnmanagedType.LPStr, SizeConst=3)] string TranCode

同意楼上 C#也有结构体

[soaringbird]

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto, Pack = 1)]
unsafe struct Test
{
fixed byte TranCode[3];
fixed byte TranDate[9];
fixed byte TranTime[7];
fixed byte Operator[4];
}
