c++的一个结构如何转换成C
c++的一个结构怎么转换成C#
typedef struct _BtSdkRemoteServiceAttrStru
{
unsigned short mask; union
{
unsigned short svc_class; unsigned short service_class;
}; unsigned long dev_hdl; unsigned char svc_name[BTSDK_SERVICENAME_MAXLENGTH];
void * ext_attributes;
unsigned short status;
} BtSdkRemoteServiceAttrStru, *PBtSdkRemoteServiceAttrStru;
C++里的结构如上，函数调用的时候是一个BtSdkRemoteServiceAttrStru*的指针，
请问在C#里该怎么写，谢谢各位！！！！
------解决方案--------------------
按照struct的顺序依次翻译：
struct直接对应
Union与struct对应
------解决方案--------------------
typedef struct _BtSdkRemoteServiceAttrStru
{
unsigned short mask; union
{
unsigned short svc_class; unsigned short service_class;
}; unsigned long dev_hdl; unsigned char svc_name[BTSDK_SERVICENAME_MAXLENGTH];
void * ext_attributes;
unsigned short status;
} BtSdkRemoteServiceAttrStru, *PBtSdkRemoteServiceAttrStru;

按照struct的顺序依次翻译：
struct直接对应
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi, Pack = 1)]
public struct
{
//字符串使用
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = BTSDK_SERVICENAME_MAXLENGTH)]
public string svc_name;
}
Union与struct对应
[System.Runtime.InteropServices.StructLayout(LayoutKind.Explicit)]
public struct unionStruct
{
[FieldOffset(0)]
Uint16 svc_class;
[FieldOffset(0)]
Uint16 service_class;
}
------解决方案--------------------
[System.Runtime.InteropServices.StructLayoutAttribute(System.Runtime.InteropServices.LayoutKind.Explicit)]
public struct Anonymous
{
/// unsigned short
[System.Runtime.InteropServices.FieldOffsetAttribute(0)]
public ushort svc_class;
/// unsigned short
[System.Runtime.InteropServices.FieldOffsetAttribute(0)]
public ushort service_class;
}
[System.Runtime.InteropServices.StructLayoutAttribute(System.Runtime.InteropServices.LayoutKind.Sequential, CharSet=System.Runtime.InteropServices.CharSet.Ansi)]
public struct BtSdkRemoteServiceAttrStru
{
/// unsigned short
public ushort mask;
/// Anonymous
public Anonymous Union1;
/// unsigned int
public uint dev_hdl;
/// unsigned char[]
[System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.ByValTStr, SizeConst=-1)]
public string svc_name;
/// void*
public System.IntPtr ext_attributes;
/// unsigned short
public ushort status;
