c的结构在c#里的定义方法

?

typedef struct{

songinfo  songs[5];

int      foundnum;

}QUERYRESULT;

  

typedef struct{

int id;

int hits;

char name[80];

float spos[5];

int sposnum;

}songinfo;

 

c#

?

[StructLayout(LayoutKind.Sequential, Pack = 1)]

public struct QueryResult

{

    [MarshalAs(UnmanagedType.ByValArray, SizeConst = 5)]

     public SongInfo[] songs;//检索到的音频信息列表

     public int foundnum; //检索到的音频数量

 }

 

 [StructLayout(LayoutKind.Sequential, Pack = 1)]

 public struct SongInfo

 {

     public int id; //该音频文件对应的id号

     public int hits; //待检索音频与该音频对应的冲撞值

     public string name; //音频对应的文件名

     [MarshalAs(UnmanagedType.ByValArray, SizeConst = 5)]

     public float[] spos;//待检索音频数据在该音频中的起始时间

     public int sposnum; //待检索音频数据在音频中的位置数量
