c＃如何使用新版本的助手API

由于Osversion现在不可靠，因为Windows 10已经发布（这个函数报告Windows 10的Windows 10），我试图在我的C＃应用程序中使用新的版本帮助器API函数。他们在这里。

我很抱歉，如果这只是我的DLL导入问题，但这里是我试图拉入这些新的方法来正确检测操作系统。

[DllImport("kernel32.dll",CharSet = CharSet.Auto)] public static extern bool IsWindows7OrGreater(); [DllImport("kernel32.dll",CharSet = CharSet.Auto)] public static extern bool IsWindows8OrGreater(); [DllImport("kernel32.dll",CharSet = CharSet.Auto)] public static extern bool IsWindows8Point1OrGreater(); [DllImport("kernel32.dll",CharSet = CharSet.Auto)] public static extern bool IsWindows10OrGreater();

每当我调用这些方法，我得到：

exception是：EntryPointNotFoundException – 无法在DLL'kernel32.dll'中find名为“IsWindows7OrGreater”的入口点。

难道我做错了什么？有人有主意吗？谢谢你的帮助！

不幸的是，这比这更复杂一点。 “函数”实际上是在VersionHelpers.h定义的宏。

如果你想到了，这是唯一的方法 – 他们不能追溯功能添加到较旧的Windows版本。

您必须将宏移植到C＃。

您的代码必须包含一个Manifest

这告诉操作系统你的代码支持更新的操作系统

使用下面的类

using System; using System.Runtime.InteropServices; namespace VersionHelper { public static class VersionHelper { const byte VER_EQUAL = 1; const byte VER_GREATER = 2; const byte VER_GREATER_EQUAL = 3; const byte VER_LESS = 4; const byte VER_LESS_EQUAL = 5; const byte VER_AND = 6; const byte VER_OR = 7; const byte VER_CONDITION_MASK = 7; const byte VER_NUM_BITS_PER_CONDITION_MASK = 3; // // RtlVerifyVersionInfo() type mask bits // const uint VER_MInorVERSION = 0x0000001;

[StructLayout(LayoutKind.Sequential,CharSet = CharSet.Unicode)] struct OsveRSIONINFOEXW { public int dwOsversionInfoSize; public int dwMajorVersion; public int dwMinorVersion; public int dwBuildNumber; public int dwPlatformId; [MarshalAs(UnmanagedType.ByValTStr,SizeConst = 128)] public string szCSDVersion; public UInt16 wServicePackMajor; public UInt16 wServicePackMinor; public UInt16 wSuiteMask; public byte wProductType;

var dwlConditionMask = VerSetConditionMask( VerSetConditionMask( VerSetConditionMask( 0,VER_MAJORVERSION,VER_GREATER_EQUAL),VER_MInorVERSION,VER_SERVICEPACKMAJOR,VER_GREATER_EQUAL); osvi.dwMajorVersion = wMajorVersion;

} public static bool IsWindowsVistaSP2OrGreater() { return IsWindowsversionorGreater(HIBYTE(_WIN32_WINNT_VISTA),2); } public static bool IsWindows7OrGreater() { return IsWindowsversionorGreater(HIBYTE(_WIN32_WINNT_WIN7),LOBYTE(_WIN32_WINNT_WIN7),0);

var dwlConditionMask = VerSetConditionMask(0,VER_PRODUCT_TYPE,VER_EQUAL); return !VerifyVersionInfoW( ref osvi,dwlConditionMask); } } }

VersionHelpers函数不会在任何dll中导出，而是在VersionHelpers.h文件中定义的，为了利用C＃代码中的功能，您可以从头文件复制功能，

导入这两个功能：

[DllImport("kernel32.dll")] static extern ulong VerSetConditionMask(ulong dwlConditionMask,uint dwTypeBitMask,byte dwConditionMask); [DllImport("kernel32.dll")] static extern bool VerifyVersionInfo([In] ref OsversionInfoEx lpVersionInfo,ulong dwlConditionMask);

定义以下结构：

[StructLayout(LayoutKind.Sequential)] struct OsversionInfoEx { public uint OsversionInfoSize; public uint MajorVersion; public uint MinorVersion; public uint BuildNumber; public uint PlatformId; [MarshalAs(UnmanagedType.ByValTStr,SizeConst = 128)] public string CSDVersion; public ushort ServicePackMajor; public ushort ServicePackMinor; public ushort SuiteMask; public byte ProductType; public byte Reserved; }

然后使用以下功能：

static bool IsWindowsversionorGreater(uint majorVersion,uint minorVersion,ushort servicePackMajor) { OsversionInfoEx osvi = new OsversionInfoEx(); osvi.OsversionInfoSize = (uint)Marshal.SizeOf(osvi); osvi.MajorVersion = majorVersion; osvi.MinorVersion = minorVersion; osvi.ServicePackMajor = servicePackMajor; // These constants initialized with corresponding deFinitions in // winnt.h (part of Windows SDK) const uint VER_MInorVERSION = 0x0000001; const uint VER_MAJORVERSION = 0x0000002; const uint VER_SERVICEPACKMAJOR = 0x0000020; const byte VER_GREATER_EQUAL = 3; ulong versionorGreaterMask = VerSetConditionMask( VerSetConditionMask( VerSetConditionMask( 0,VER_GREATER_EQUAL); uint versionorGreaterTypeMask = VER_MAJORVERSION |VER_MInorVERSION | VER_SERVICEPACKMAJOR; return VerifyVersionInfo(ref osvi,versionorGreaterTypeMask,versionorGreaterMask);

}
