Winform

 不规则 窗体 实现

设置窗体属性TransparencyKey的颜色和需要屏蔽的颜色一致即可

App.config读写

读：
System.Configuration.ConfigurationSettings.AppSettings["KeyName"]

写：
XmlDocument doc = new XmlDocument();
doc.Load(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
XmlNodeList nodes = doc.GetElementsByTagName("add");
foreach (XmlNode node in nodes)
{
    XmlElement xe = (XmlElement)node;
    if (xe.GetAttribute("key") == "KeyName")
    xe.SetAttribute("value",value);
}
ConfigurationManager.RefreshSection("add");
doc.Save(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);

FindControl 的函数 遍历 控件

public static System.Windows.Forms.Control FindControl(System.Windows.Forms.Control p_Control, string p_ControlName)
        {
            if (p_Control.Name == p_ControlName) return p_Control;
            for (int i = 0; i != p_Control.Controls.Count; i++)
            {
                System.Windows.Forms.Control _SubControl = FindControl(p_Control.Controls[i], p_ControlName);
                if (_SubControl != null) return _SubControl;
            }
            return null;
        }

       返回的是object对象

            double 运距 = 0;

‍             object tb = FindControl(this, "tb");
            if (tb != null)
            {
                double.TryParse((tb as TextBox).Text, out 运距);
            }

系统浏览器打开网址

System.Diagnostics.Process.Start("explorer.exe", "http://www.baidu.com");
e.g.
    string str = "\""+tb_PubAddress1.Text.Trim()+"\""; //前后需要加载引号，否则无法开启
    System.Diagnostics.Process.Start("explorer.exe", str);
