Question

如题所述

Answer 1

可以用xml来保存

//读取程序配置
private void LoadConfig()
{
XmlDocument xdo = new XmlDocument();
xdo.Load(Application.StartupPath + @"\Config.xml");
XmlNode head = xdo.SelectSingleNode("Config");
XmlNode Point1_x = head.SelectSingleNode("Point1_x");
XmlNode Point1_y = head.SelectSingleNode("Point1_y");
XmlNode Point2_x = head.SelectSingleNode("Point2_x");
XmlNode Point2_y = head.SelectSingleNode("Point2_y");
XmlNode Point3_x = head.SelectSingleNode("Point3_x");
XmlNode Point3_y = head.SelectSingleNode("Point3_y");
XmlNode time = head.SelectSingleNode("time");
XmlNode count = head.SelectSingleNode("count");
this.txtb_x1.Text = Point1_x.InnerText;
this.txtb_y1.Text = Point1_y.InnerText;
this.txtb_x2.Text = Point2_x.InnerText;
this.txtb_y2.Text = Point2_y.InnerText;
this.txtb_x3.Text = Point3_x.InnerText;
this.txtb_y3.Text = Point3_y.InnerText;
this.txtb_time.Text = time.InnerText;
this.txtb_count.Text = count.InnerText;

} //保存程序配置
private bool SaveConfig()
{
try
{
XmlDocument xdo = new XmlDocument();
xdo.Load(Application.StartupPath + @"\Config.xml");
XmlNode head = xdo.SelectSingleNode("Config");
XmlNode Point1_x = head.SelectSingleNode("Point1_x");
XmlNode Point1_y = head.SelectSingleNode("Point1_y");
XmlNode Point2_x = head.SelectSingleNode("Point2_x");
XmlNode Point2_y = head.SelectSingleNode("Point2_y");
XmlNode Point3_x = head.SelectSingleNode("Point3_x");
XmlNode Point3_y = head.SelectSingleNode("Point3_y");
XmlNode time = head.SelectSingleNode("time");
XmlNode count = head.SelectSingleNode("count");
Point1_x.InnerText = this.txtb_x1.Text.Trim();
Point1_y.InnerText = this.txtb_y1.Text.Trim();
Point2_x.InnerText = this.txtb_x2.Text.Trim();
Point2_y.InnerText = this.txtb_y2.Text.Trim();
Point3_x.InnerText = this.txtb_x3.Text.Trim();
Point3_y.InnerText = this.txtb_y3.Text.Trim();
time.InnerText = this.txtb_time.Text.Trim();
count.InnerText = this.txtb_count.Text.Trim();
xdo.Save(Application.StartupPath + @"\Config.xml");
return true;
}
catch
{
return false;
}
}
//创建配置文件
private bool CreateConfig()
{
try
{
XmlTextWriter xmlwriter = new XmlTextWriter(Application.StartupPath + @"\Config.xml", Encoding.Default);
xmlwriter.WriteStartDocument();
xmlwriter.WriteStartElement("Config");

xmlwriter.WriteElementString("Point1_x", "0");
xmlwriter.WriteElementString("Point1_y", "0");
xmlwriter.WriteElementString("Point2_x", "0");
xmlwriter.WriteElementString("Point2_y", "0");
xmlwriter.WriteElementString("Point3_x", "0");
xmlwriter.WriteElementString("Point3_y", "0");

xmlwriter.WriteElementString("time", "1000");
xmlwriter.WriteElementString("count", "1");

xmlwriter.WriteEndElement();

xmlwriter.WriteEndDocument();
xmlwriter.Close();
return true;
}
catch
{
return false;
}

}

你就在改变选中状态的事件里去写保存的代码啊。。。追问

我要在下次再打开的时候可以自动加载

追答

那就在窗体加载的时候读取一下配置文件啊，不过这里要注意你要先读取配置文件然后再生成checkbox或者写一个读取配置文件的方法放在窗体构造函数中初始化函数的前面，否则你新做出来的checkbox的默认属性是等于false的这样就又写回去了

我只会保存到配置文件操作INI文件
