关于x64问题的FILETIME. [英] FILETIME on x64 question.

问题描述

我正在使用FILETIME结构进行互操作.它似乎可以在我的comp上正常工作，但是在x64体系结构上会出现一些问题吗?

I''m using my FILETIME structure for interop. It seems to work on my comp ,but will I have some problems on x64 architectures?

[StructLayout(LayoutKind.Explicit)]
public struct FILETIME
{
    [FieldOffset(0)]
    public int dwLowDateTime;
    [FieldOffset(4)]
    public int dwHighDateTime;
    [FieldOffset(0)]
    public long QuadDateTime;
}

我正在访问结构的四部分，而不是分别访问低和高，以在DateTime之间进行转换.

I''m accessing quad part of the structure instead of low and high separately for converting between DateTime.

推荐答案

请查看

Look at pinvoke.net FILETIME (Structures)[^]

FILETIME is defined as:

[StructLayout(LayoutKind.Sequential)]
struct FILETIME {
    public uint DateTimeLow;
    public uint DateTimeHigh;
}

没有FieldOffSet.但这取决于您要调用的Win32函数返回的FILETIME.

With no FieldOffSet. But it depends on what Win32 function you are calling that returns a FILETIME.
