C%23程序开发中经常遇到的10条实用的代码.docxVIP

1读取操作系统和CLR的版本OperatingSystemos=System.Environment.OSVersion;Console.WriteLine(“Platform:{0}”,os.Platform);Console.WriteLine(“ServicePack:{0}”,os.ServicePack);Console.WriteLine(“Version:{0}”,os.Version);Console.WriteLine(“VersionString:{0}”,os.VersionString);Console.WriteLine(“CLRVersion:{0}”,System.Environment.Version); 在我的Windows7系统中，输出以下信息Platform:Win32NT ServicePack: Version:6.1.7600.0 VersionString:MicrosoftWindowsNT6.1.7600.0 CLRVersion:4.0.21006.1 2读取CPU数量，内存容量可以通过WindowsManagementInstrumentation(WMI)提供的接口读取所需要的信息。privatestaticUInt32CountPhysicalProcessors(){ManagementObjectSearcherobjects=newManagementObjectSearcher(“SELECT*FROMWin32_ComputerSystem”);ManagementObjectCollectioncoll=objects.Get();foreach(ManagementObjectobjincoll){return(UInt32)obj[“NumberOfProcessors”];}return0;}privatestaticUInt64CountPhysicalMemory(){ManagementObjectSearcherobjects=newManagementObjectSearcher(“SELECT*FROMWin32_PhysicalMemory”);ManagementObjectCollectioncoll=objects.Get();UInt64total=0;foreach(ManagementObjectobjincoll){total+=(UInt64)obj[“Capacity”];}returntotal;}请添加对程序集System.Management的引用，确保代码可以正确编译。Console.WriteLine(“Machine:{0}”,Environment.MachineName);Console.WriteLine(“#ofprocessors(logical):{0}”,Environment.ProcessorCount);Console.WriteLine(“#ofprocessors(physical):{0}”CountPhysicalProcessors());Console.WriteLine(“RAMinstalled:{0:N0}bytes”,CountPhysicalMemory());Console.WriteLine(“IsOS64-bit?{0}”,Environment.Is64BitOperatingSystem);Console.WriteLine(“Isprocess64-bit?{0}”,Environment.Is64BitProcess);Console.WriteLine(“Little-endian:{0}”,BitConverter.IsLittleEndian);foreach(ScreenscreeninSystem.Windows.Forms.Screen.AllScreens){Console.WriteLine(“Screen{0}”,screen.DeviceName);Console.WriteLine(“\tPrimary{0}”,screen.Primary);Console.WriteLine(“\tBounds:{0}”,screen.Bounds);Console.WriteLine(“\tWorkingArea:{0}”,screen.WorkingArea);Console.WriteLine(“\tBitsPerPixel:{0}”,screen.BitsPerPixel);}  3读取注册表键值对using(RegistryKeykeyRun=Registry.LocalMachine.OpenSubKey(@”Software
