XML结构文件的读写

附件:http://files.cnblogs.com/xe2011/XML_Writer_And_Read.rar

下面这段代码实现了以下功能

数据保存 textBox1的文本,textBox2的文本，窗体的LEFT TOP WIDTH HEIGHT

读取数据 textBox1的文本,textBox2的文本，窗体的LEFT TOP WIDTH HEIGHT

引用XML

using System.Xml;

用XmlTextWriter 创建一个XML结构文件

 private void button1_Click(object sender, EventArgs e)
        {
            XmlTextWriter xml = new XmlTextWriter("WindowsFormsApplicationConfig.xml", Encoding.UTF8);
            xml.WriteStartDocument();
                xml.WriteStartElement("配置信息");

                    xml.WriteStartElement("Form1");
                        xml.WriteElementString("Left",   this.Left.ToString());
                        xml.WriteElementString("Top",    this.Top.ToString());
                        xml.WriteElementString("Width",  this.Width.ToString());
                        xml.WriteElementString("Height", this.Height.ToString());
                    xml.WriteEndElement();

                    xml.WriteStartElement("TextBox1");
                     xml.WriteElementString("Text", textBox1.Text);
                    xml.WriteEndElement();

                    xml.WriteStartElement("TextBox2");
                        xml.WriteElementString("Text", textBox2.Text);
                    xml.WriteEndElement();

                xml.WriteEndElement();
            xml.WriteEndDocument();
            xml.Close();
        }

读取XML文件

   private void button2_Click(object sender, EventArgs e)
        {

            XmlTextReader xml = new XmlTextReader("WindowsFormsApplicationConfig.xml");
            while (xml.Read())
            {
                xml.ReadStartElement("配置信息");

                    xml.ReadStartElement("Form1");
                        Left   = Convert.ToInt32(xml.ReadElementString("Left"));
                        Top    = Convert.ToInt32(xml.ReadElementString("Top"));
                        Width  = Convert.ToInt32(xml.ReadElementString("Width"));
                        Height = Convert.ToInt32(xml.ReadElementString("Height"));
                    xml.ReadEndElement();

                    xml.ReadStartElement("TextBox1");
                      textBox1.Text = xml.ReadElementString("Text");
                    xml.ReadEndElement();

                    xml.ReadStartElement("TextBox2");
                      textBox2.Text = xml.ReadElementString("Text");
                    xml.ReadEndElement();

                xml.ReadEndElement();
            }
            xml.Close();
        }
