如何序列化一个对象

首先创建一个可以被序列化的类
[Serializable()]
然后对它添加属性.字段

需要添加
using System.Xml.Serialization;

            XmlSerializer ser = new XmlSerializer(typeof(SiteInfoCollection));
            
            System.IO.StringWriter s = new System.IO.StringWriter();

            SiteInfo siteInfo = new SiteInfo();
            siteInfo.Depth= 2;
            siteInfo.Domain ="www.bac.com";
            siteInfo.ProductRegx = new List<string>();
            siteInfo.ProductRegx.Add("xxxx");
            siteInfo.ProductRegx.Add("wwwxxx");
            SiteInfoCollection cc = new SiteInfoCollection();
            cc.Add(siteInfo);
            siteInfo.Domain = "www.qq.com";
            cc.Add(siteInfo);
            ser.Serialize(s,cc);

            richTextBox1.Text = s.ToString();
