Question

我正在创建一个程序，将NumericUpDown-Box中的Mouse X和Mouse Y坐标保存到Settings.settings中，以便程序以最后使用的值启动。

当“ValueChanged”as seen here

时，两个输入框都会调用方法“saveXY”

我的问题是：X坐标保存没有问题，Y坐标根本没有保存 - 但代码是相同的：

    private void Form1_Load(object sender, EventArgs e)
    {
        movetoX.Value = Settings.Default.mouseX;
        movetoY.Value = Settings.Default.mouseY;
    }

-

    private void saveXY(object sender, EventArgs e)
    {
        Settings.Default.mouseX = (int)movetoX.Value;
        Settings.Default.mouseY = (int)movetoY.Value;
        Settings.Default.Save();
    }

Theese是我的Settings.settings。

.exe是可用的here。

更新1：

必须执行Properties.Settings.Default.Upgrade（），然后才能加载已保存的设置。

<强>示例

public Form1()
{
   InitializeComponent();
   //Load saved settings

   this.Location = Properties.Settings.Default.Form1Location;
   this.Size = Properties.Settings.Default.Form1Size;
   //Allow changes to be implemented

   this.StartPosition = FormStartPosition.Manual;
   //capture changes

   this.LocationChanged += new EventHandler(Form1_LocationChanged);
   this.SizeChanged += new EventHandler(Form1_SizeChanged);
   //capture the closing form event to save your new settings

   this.FormClosed += new FormClosedEventHandler(Form1_FormClosed);
}
void Form1_LocationChanged(object sender, EventArgs e)
{
   //Capture the new values

   Properties.Settings.Default.Form1Location = this.Location;
}
void Form1_SizeChanged(object sender, EventArgs e)
{
   //Capture the new values

   Properties.Settings.Default.Form1Size = this.Size;
}
void Form1_FormClosed(object sender, FormClosedEventArgs e)
{
   //you can capture the new values here as well    
   //save the new values

   Properties.Settings.Default.Save();
}

感谢hamix，现在正在工作

我删除了saveXY并写了这个：

    private void Form1_FormClosed(object sender, FormClosedEventArgs e)
    {
        Settings.Default.mouseX = (int)movetoX.Value;
        Settings.Default.mouseY = (int)movetoY.Value;
        Settings.Default.Save();
    }

现在可以保存X和Y

Visual C＃ - Properties.Settings无法正确保存
