推荐答案

XML简介序列化 [ ^ ]。

参考 XmlSerializer类（System.Xml.Serialization） [ ^ ]类



按照步骤

创建一个实体表单中的属性为

refer XmlSerializer Class (System.Xml.Serialization)[^] class

follow the steps
Create an entity with the properties in the form as

public class MyEntity
   {
       public string Name { get; set; }
       public string Age { get; set; }
       public string Address { get; set; }
   }

以下代码用于使用Asp.net应用程序，但概念相同mvc或窗口等。

the below code is for using Asp.net application, however the concept is same for mvc or window etc..

protected void btnSave_Click(object sender, EventArgs e)
        {
            // create a folder 'xmlfiles' in the root directory
            string filePath = Server.MapPath("xmlfiles") + "//" +  "myfile.xml"; //  Path for the xml

            MyEntity entity = new MyEntity();
            // initalise the properties of the entity 
            entity.Name = txtName.Text;
            entity.Age = txtAge.Text;
            entity.Address = txtAddress.Text;
            // end 

            XmlSerializer xs = new XmlSerializer(typeof(MyEntity));
            TextWriter tw = new StreamWriter(filePath);
            xs.Serialize(tw, entity);
        }

嗯......实现这个目标的方法很少：



1）正如前辈所写：XmlSerialization对你来说是最好的选择

XML序列化和反序列化：第1部分 [ ^ ]

XML序列化和反序列化：第2部分 [ ^ ]

自定义类集合序列化和反序列化的完整示例 [ ^ ]



2）使用 XDocument类（System.Xml.Linq） [ ^ ]



3） 使用 XmlDocument Class [< a href =https://msdn.microsoft.com/en-us/library/system.xml.xmldocument(v=vs.110).aspx\"target =_ blanktitle =New Window> ^ ]



4）使用 DataTable [ ^ ]的WriteXml方法（字符串） [ ^ ]和 ReadXml方法（字符串）（System.Data） [ ^ ]



试试！

Well... There's few ways to achieve that:

1) As the predecessors wrote: XmlSerialization is the best option for you
XML Serialization and Deserialization: Part-1[^]
XML Serialization and Deserialization: Part-2[^]
A Complete Sample of Custom Class Collection Serialization and Deserialization[^]

2) using XDocument Class (System.Xml.Linq)[^]

3) using XmlDocument Class [^]

4) using DataTable[^]'s WriteXml Method (String)[^] and ReadXml Method (String) (System.Data)[^]

Try!
