本文介绍了将具有固定大小数组的 C++ 结构编组到 C#的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
I have a C# struct declared like so:
public struct AdvertisementData {
public byte SomeId;
[MarshalAs(UnmanagedType.LPArray , SizeConst = 12)]
public byte[] AnArray;
}
And it's C++ counterpart:
struct AdvertisementData {
uint8_t SomeId;
uint8_t AnArray[12];
};
When I try to send a reference to a stack-allocated instance of the above struct from C++ to C#, I get: "Structure field of type Byte[] can't be marshalled as LPArray." Any idea what I'm doing wrong?
解决方案
Try to marshal it as ByValArray:
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 12)]
public byte[] AnArray;
And also, are you sure that you do not need to set any LayoutKind for your struct?
