如何在上次关闭位置启动程序窗体!!!!!

Answer 1

在settings.setting文件中加入：
WindowGeometry  string    User  
WindowGeometryOpen   string   User 
WindowGeometrySearch  string   User相关代码：
public MainForm()
{
 GeometryFromString(Properties.Settings.Default.WindowGeometry, this);
}private void MainForm_FormClosing(object sender, FormClosingEventArgs e)
        {
            // persist our geometry string.
            Properties.Settings.Default.WindowGeometry = GeometryToString(this);
            Properties.Settings.Default.Save();        }#region 保存窗体位置、大小
        public void GeometryFromString(string thisWindowGeometry, Form formIn)
        {
            if (string.IsNullOrEmpty(thisWindowGeometry) == true)
            {
                return;
            }
            string[] numbers = thisWindowGeometry.Split('|');
            string windowString = numbers[4];
            if (windowString == "Normal")
            {
                Point windowPoint = new Point(int.Parse(numbers[0]),
                    int.Parse(numbers[1]));
                Size windowSize = new Size(int.Parse(numbers[2]),
                    int.Parse(numbers[3]));                bool locOkay = GeometryIsBizarreLocation(windowPoint, windowSize);
                bool sizeOkay = GeometryIsBizarreSize(windowSize);                if (locOkay == true && sizeOkay == true)
                {
                    formIn.Location = windowPoint;
                    formIn.Size = windowSize;
                    formIn.StartPosition = FormStartPosition.Manual;
                    formIn.WindowState = FormWindowState.Normal;
                }
                else if (sizeOkay == true)
                {
                    formIn.Size = windowSize;
                }
            }
            else if (windowString == "Maximized")
            {
                formIn.Location = new Point(100, 100);
                formIn.StartPosition = FormStartPosition.Manual;
                formIn.WindowState = FormWindowState.Maximized;
            }
        }
        private bool GeometryIsBizarreLocation(Point loc, Size size)
        {
            bool locOkay;
            if (loc.X < 0 || loc.Y < 0)
            {
                locOkay = false;
            }
            else if (loc.X + size.Width > Screen.PrimaryScreen.WorkingArea.Width)
            {
                locOkay = false;
            }
            else if (loc.Y + size.Height > Screen.PrimaryScreen.WorkingArea.Height)
            {
                locOkay = false;
            }
            else
            {
                locOkay = true;
            }
            return locOkay;
        }        private static bool GeometryIsBizarreSize(Size size)
        {
            return (size.Height <= Screen.PrimaryScreen.WorkingArea.Height &&
                size.Width <= Screen.PrimaryScreen.WorkingArea.Width);
        }        public string GeometryToString(Form mainForm)
        {
            return mainForm.Location.X.ToString() + "|" +
                mainForm.Location.Y.ToString() + "|" +
                mainForm.Size.Width.ToString() + "|" +
                mainForm.Size.Height.ToString() + "|" +
                mainForm.WindowState.ToString();
        }        #endregion

C#中使用Setting保存用户自定义窗体位置及大小
很早在codeproject上看到的！

Answer 3

设置Application属性的Location
然后在关闭函数里面写Properties.Settings.Default.Save();
