## 场景 ##

Winform中对DevExpress的RadioGroup进行数据源绑定，即通过代码添加选项：

Winform中自定义xml配置文件后对节点进行读取与写入：

结合上面两种效果实现打开一个新的窗体后，此窗体上的RadioGroup的选项是根据配置文件

中的配置自动生成的。

配置文件代码如下：

<?xml version="1.0" encoding="utf-8"?>
    <Configure>
      
      <YAxis>
        
        <YAxi>
          <no>1</no>
          <title>霸道</title>
          <color>black</color>
          <min>-1500</min>
          <max>1500</max>
        </YAxi>
        
        <YAxi>
          <no>2</no>
          <title>电压</title>
          <color>black</color>
          <min>-1500</min>
          <max>1500</max>
        </YAxi>
        <YAxi>
          <no>3</no>
          <title>badao</title>
          <color>red</color>
          <min>-1600</min>
          <max>1600</max>
        </YAxi>
      </YAxis>
    </Configure>

## 实现 ##

新建一个窗体并拖拽一个RadioGroup控件。

双击窗体进入其加载完之后的事件中

private void EditY_Load(object sender, EventArgs e)
            {
                List<YAxisModel> nodeYList = new List<YAxisModel>();
                //获取可执行文件的路径-即bin目录下的debug或者release目录
                string context = System.Windows.Forms.Application.StartupPath;
                string path = String.Concat(context,@"\config\YAxisSet.xml");
                XmlDocument xml = new XmlDocument();
                //打开一个xml
                try
                {
                    xml.Load(path);
                    //读取节点数据
                    XmlNodeList nodeList = xml.SelectNodes("Configure/YAxis/YAxi");
                    foreach (XmlNode n in nodeList)
                    {
                       YAxisModel ya = new YAxisModel();
                       ya.No = int.Parse(n.SelectSingleNode("no").InnerText);
                       ya.Title = n.SelectSingleNode("title").InnerText;
                       ya.Color = n.SelectSingleNode("color").InnerText;
                       ya.Min = double.Parse(n.SelectSingleNode("min").InnerText);
                       ya.Max = double.Parse(n.SelectSingleNode("max").InnerText);
                       nodeYList.Add(ya);
                    }
                }
                catch (Exception ex)
                {
                    Console.WriteLine(ex.Message);
                }
               
                //数据绑定
                foreach (YAxisModel s in nodeYList)
                {
                    //每一个单元按钮对应的选线item
                    RadioGroupItem item = new RadioGroupItem();
                    //设置选项的value值
                    item.Value = s.No;
                    //设置选项的描述值 即 要显示的值
                    item.Description = s.Title;
                    //使选项启用
                    item.Enabled = true;
                    //将新增的选项添加到radiogroup的Items中
                    this.radioGroup1.Properties.Items.Add(item);
                }
               //默认选中value为1的项
                radioGroup1.EditValue = 1;
             }

在此之前要新建一个对象用来存取读取的配置文件的YAxi节点的属性。

using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    
    namespace ZedGraphTest.model
    {
        class YAxisModel
        {
            private int no;
    
            public int No
            {
                get { return no; }
                set { no = value; }
            }
            private string title;
    
            public string Title
            {
                get { return title; }
                set { title = value; }
            }
            private string color;
    
            public string Color
            {
                get { return color; }
                set { color = value; }
            }
            private double min;
    
            public double Min
            {
                get { return min; }
                set { min = value; }
            }
            private double max;
    
            public double Max
            {
                get { return max; }
                set { max = value; }
            }
        }
    }
