在不使用“固定”的情况下，如何访问结构中数组的值？
|
我正在做C ++-> C＃互操作的东西，我有一堆相互包含的结构，例如Matryoshka娃娃。问题是这些“嵌套”之一采用固定长度数组的形式：
typedef struct tagBIRDREADING
{
BIRDPOSITION position;
BIRDANGLES angles;
BIRDMATRIX matrix;
BIRDQUATERNION quaternion;
WORD wButtons;
}
BIRDREADING;
typedef struct tagBIRDFRAME
{
DWORD dwTime;
BIRDREADING reading[BIRD_MAX_DEVICE_NUM + 1];
}
BIRDFRAME;
[StructLayout(LayoutKind.Sequential, Pack = 0)]
public struct BIRDREADING
{
public BIRDPOSITION position;
public BIRDANGLES angles;
public BIRDMATRIX matrix;
public BIRDQUATERNION quaternion;
public ushort wButtons;
}
[StructLayout(LayoutKind.Sequential, Size = 127)]
public struct BIRDREADINGa
{
public BIRDREADING reading;
}
public struct BIRDFRAME
{
public uint dwTime;
public BIRDREADINGa readings;
}
BIRDREADINGa
BIRDREADING
没有找到相关结果

[StructLayout(LayoutKind.Sequential)] public struct BIRDFRAME { public uint dwTime; [MarshalAs(UnmanagedType.ByValArray, SizeConst=127)] public BIRDREADING[] readings; }场竟矩喘崩
public struct BIRDREADINGa { public BIRDREADING reading; public BIRDREADING GetReading(int index) { unsafe { fixed(BIRDREADING* r = &reading) { return *(r + index); } } } }
