struct和byte[]相互转换（用Marshal类实现）

1、struct转换为byte[]

static byte[] StructToBytes(object structObj)
{
    int size = Marshal.SizeOf(structObj);
    IntPtr buffer = Marshal.AllocHGlobal(size);
    try
    {
        Marshal.StructureToPtr(structObj, buffer, false);
        byte[] bytes = new byte[size];
        Marshal.Copy(buffer, bytes, 0, size);
        return bytes;
    }
    finally
    {
        Marshal.FreeHGlobal(buffer);
    }
}

 
2、byte[]转换为struct

 

static object BytesToStruct(byte[] bytes, Type strcutType)
{
    int size = Marshal.SizeOf(strcutType);
    IntPtr buffer = Marshal.AllocHGlobal(size);
    try
    {
        Marshal.Copy(bytes, 0, buffer, size);
        return Marshal.PtrToStructure(buffer, strcutType);
    }
    finally
    {
        Marshal.FreeHGlobal(buffer);
    }
}
