我正在使用GlobalMemoryStatusEx函数来检索有关内存的信息,但是此功能无法正常工作.它为所有属性返回0.我不认为这个功能在我的
Windows 7环境中有效.
- [StructLayout(LayoutKind.Sequential)]
- internal struct MEMORYSTATUSEX
- {
- internal uint dwLength;
- internal uint dwMemoryLoad;
- internal ulong ullTotalPhys;
- internal ulong ullAvailPhys;
- internal ulong ullTotalPageFile;
- internal ulong ullAvailPageFile;
- internal ulong ullTotalVirtual;
- internal ulong ullAvailVirtual;
- internal ulong ullAvailExtendedVirtual;
- }
- [return: MarshalAs(UnmanagedType.Bool)]
- [DllImport("Kernel32.dll",CharSet = CharSet.Auto,SetLastError = true)]
- internal static extern bool GlobalMemoryStatusEx(ref MEMORYSTATUSEX lpBuffer);
- private void btnGlobalMemoryStatusEX_Click(object sender,EventArgs e)
- {
- MEMORYSTATUSEX statEX = new MEMORYSTATUSEX();
- GlobalMemoryStatusEx(ref statEX);
- double d = (double)statEX.ullTotalPhys;
- }
解决方法
我发现我的错误：
http://www.pinvoke.net/default.aspx/kernel32/GlobalMemoryStatusEx.html
http://www.pinvoke.net/default.aspx/kernel32/GlobalMemoryStatusEx.html
我变了
- internal static extern bool GlobalMemoryStatusEx(ref MEMORYSTATUSEX lpBuffer);
至
- static extern bool GlobalMemoryStatusEx([In,Out] MEMORYSTATUSEX lpBuffer);
并改变了
- GlobalMemoryStatusEx(ref statEX);
至
- GlobalMemoryStatusEx(statEX);
它正常工作坦克
