在一些系统软件开发中,常常将一些软件运行环境、系统配置等信息写入到注册表中,除非是所谓的绿色软件。


    在Windows平台上的软件,几乎都会和注册表打交道。在本节中,将介绍如何将信息写入到注册表中。

//首先包含如下引用

using Microsoft.Win32;

//写注册表

void SaveSettings()

              {

                     RegistryKeySoftwareKey=Registry.LocalMachine.OpenSubKey("Software",true);

                     RegistryKeyMovecontKey=SoftwareKey.CreateSubKey("Movecont");//建立

                     RegistryKeySelfPlaceKey=MovecontKey.CreateSubKey("SelfPlace");//建立

                     SelfPlaceKey.SetValue("BackColor",(object)BackColor.ToKnownColor());//写

                     SelfPlaceKey.SetValue("Red",(object)(int)BackColor.R);//红

                     SelfPlaceKey.SetValue("Green",(object)(int)BackColor.G);//绿

                     SelfPlaceKey.SetValue("Blue",(object)(int)BackColor.B);//蓝

                     SelfPlaceKey.SetValue("Width",(object)Width);//宽

                     SelfPlaceKey.SetValue("Height",(object)Height);//高

                     SelfPlaceKey.SetValue("X",(object)DesktopLocation.X);//左上角X坐标

                     SelfPlaceKey.SetValue("Y",(object)DesktopLocation.Y);//左上角Y坐标

                     SelfPlaceKey.SetValue("WindowState",(object)WindowState.ToString());//左上角Y坐标

 

              }

//读注册表

bool ReadSettings()

              {

                     RegistryKeySoftwareKey=Registry.LocalMachine.OpenSubKey("Software",true);

                     RegistryKeyMovecontKey=SoftwareKey.OpenSubKey("Movecont");//建立

                     if(MovecontKey==null)

                            returnfalse;

                     RegistryKeySelfPlaceKey=MovecontKey.OpenSubKey("SelfPlace");//建立

                     if(SelfPlaceKey==null)

                            returnfalse;

                     else

                            this.listBoxMessages.Items.Add("成功打开注册表!");

                     intRed=(int)SelfPlaceKey.GetValue("Red");

                     intGreen=(int)SelfPlaceKey.GetValue("Green");

                     intBlue=(int)SelfPlaceKey.GetValue("Blue");

                     BackColor=Color.FromArgb(Red,Green,Blue);

                     this.listBoxMessages.Items.Add("BackcolorName:"+BackColor.Name);

                     intX=(int)SelfPlaceKey.GetValue("X");

                     intY=(int)SelfPlaceKey.GetValue("Y");

                     DesktopLocation=newPoint(X,Y);

                     this.listBoxMessages.Items.Add("Location:"+DesktopLocation.ToString());

                     Width=(int)SelfPlaceKey.GetValue("Width");

                     Height=(int)SelfPlaceKey.GetValue("Height");

                     this.listBoxMessages.Items.Add("Size:"+newSize(Width,Height).ToString());

                     stringInitstate=(string)SelfPlaceKey.GetValue("WindowState");

                     //****枚举类型数据的Parse

                     WindowState=(FormWindowState)FormWindowState.Parse(WindowState.GetType(),Initstate);

                     returntrue;                  

              }
