记录窗体关闭位置（从窗体上次关闭的位置启动窗体）

从上次关闭位置启动窗体

基础类

using Microsoft.Win32;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml.Linq;namespace WindowsFormsApp1
{public class Reg{public  static void Set(string name, object value,string item = "Software\\MySoft_ttd"){RegistryKey myReg1, myReg2;//声明注册表对象myReg1 = Registry.CurrentUser;//获取当前用户注册表项myReg2 = myReg1.CreateSubKey(item);//在注册表项中创建子项myReg2.SetValue(name, value);//将窗体关闭位置的x坐标写入注册表}public static object Get(string name, string item = "Software\\MySoft_ttd"){RegistryKey myReg1, myReg2;//声明注册表对象myReg1 = Registry.CurrentUser;//获取当前用户注册表项try{myReg2 = myReg1.CreateSubKey(item);//在注册表项中创建子项return myReg2.GetValue(name);}catch (Exception ex){return "0";}}}
}

调用方法

private void Form1_Load(object sender, EventArgs e){//this.Location = new Point(Convert.ToInt32(Reg.Get("my_x")), Convert.ToInt32(Reg.Get("my_y")));//https://blog.csdn.net/u014453443/article/details/90040423//if (this.Location.X >= Screen.PrimaryScreen.Bounds.Width || this.Location.Y >= Screen.PrimaryScreen.Bounds.Height)//{//    this.Location = new Point(0, 0);//}this.Left = Convert.ToInt32(Reg.Get("my_x"));this.Top = Convert.ToInt32(Reg.Get("my_y"));if (this.Left >= Screen.PrimaryScreen.Bounds.Width || this.Top >= Screen.PrimaryScreen.Bounds.Height){this.Left =0;this.Top = 0;   }}private void Form1_FormClosed(object sender, FormClosedEventArgs e){//Reg.Set("my_x", this.Location.X.ToString());//Reg.Set("my_y", this.Location.Y.ToString());Reg.Set("my_x", this.Left.ToString());Reg.Set("my_y", this.Top.ToString());}
