C#系统编程代码集合 1. 一个界面（Form1）获取另一个界面（Form2）中控件参数（一般指Text）值 private void getnumber_Click(object sender, EventArgs e) { Form2 fo2 = new Form2(); string k1 = "tb"; string k2 = "m512"; string k = k1 + k2; //控件名,实现控件名称动态化 object i = fo2.GetType().GetField(k, System.Reflection.BindingFlags.NonPublic | //反向映射System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.IgnoreCase).GetValue(fo2); //反向映射 TextBox tb = new TextBox(); tb = i as TextBox; tb1.Text = tb.Text; } 2. 多线程参数传递，使用异步委托 public delegate int threadasy(string parm); //在Form下声明委托 threadasy asy = new threadasy(threadtestpart); //线程，asy线程对象，threadtestpart线程名 IAsyncResult asyresult = asy.BeginInvoke(parm, null, null);//委托开始 int res = asy.EndInvoke(asyresult); //委托结束，int参数传递 3. XML文件创建与添加元素 private void pcbnewbulid_Click(object sender, EventArgs e) { string pcbname = pcbstype.SelectedItem.ToString(); XmlDocument xd = new XmlDocument(); //声明XML文件性质 XmlDeclaration xmlDec = xd.CreateXmlDeclaration("1.0", "utf-8", "yes"); xd.AppendChild(xmlDec); //加入一个根元素 XmlElement xmlelem = xd.CreateElement(pcbname); xd.AppendChild(xmlelem); XmlNode root = xd.SelectSingleNode(pcbname); xd.Save(@"XML//pcbname.xml"); } //添加元素 XmlElement lsffc = xmldoc.CreateElement("立式FFC排线"); addelement(xmldoc, lsffc, "xspos", xsp); //添加元素方法，可以减少工作量 private XmlElement addelement(XmlDocument doc, XmlElement ele, string tar, string value) { XmlElement nodeelem = doc.CreateElement(tar); XmlText nodetext = doc.CreateTextNode(value); ele.AppendChild(nodeelem); nodeelem.AppendChild(nodetext); return nodeelem; } 本文来源：https://www.wddqw.com/doc/46fe2c18905f804d2b160b4e767f5acfa1c7833c.html
