C#简单的 XmlSerializer 用法范例

本范例演示怎样通过c#中的XmlSerializer序列化一个普通对象

// This is the test class we want to 
// serialize:
[Serializable()]
public class TestClass
{
    private string someString;
    public string SomeString
    {
        get { return someString; }
        set { someString = value; }
    }
 
    private List<string> settings = new List<string>();
    public List<string> Settings
    {
        get { return settings; }
        set { settings = value; }
    }
 
    // These will be ignored
    [NonSerialized()]
    private int willBeIgnored1 = 1;
    private int willBeIgnored2 = 1;
 
}
 
// Example code
 
// This example requires:
// using System.Xml.Serialization;
// using System.IO;
 
// Create a new instance of the test class
TestClass TestObj = new TestClass();
 
// Set some dummy values
TestObj.SomeString = "foo";
 
TestObj.Settings.Add("A");
TestObj.Settings.Add("B");
TestObj.Settings.Add("C");
 
 
#region Save the object
 
// Create a new XmlSerializer instance with the type of the test class
XmlSerializer SerializerObj = new XmlSerializer(typeof(TestClass));
 
// Create a new file stream to write the serialized object to a file
TextWriter WriteFileStream = new StreamWriter(@"C:\test.xml");
SerializerObj.Serialize(WriteFileStream, TestObj);
 
// Cleanup
WriteFileStream.Close();
 
#endregion
 
 
/*
The test.xml file will look like this:
 
<?xml version="1.0"?>
<TestClass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <SomeString>foo</SomeString>
  <Settings>
    <string>A</string>
    <string>B</string>
    <string>C</string>
  </Settings>
</TestClass>		 
*/
 
#region Load the object
 
// Create a new file stream for reading the XML file
FileStream ReadFileStream = new FileStream(@"C:\test.xml", FileMode.Open, FileAccess.Read, FileShare.Read);
 
// Load the object saved above by using the Deserialize function
TestClass LoadedObj = (TestClass)SerializerObj.Deserialize(ReadFileStream);
 
// Cleanup
ReadFileStream.Close();
 
#endregion
 
 
// Test the new loaded object:
MessageBox.Show(LoadedObj.SomeString);
 
foreach (string Setting in LoadedObj.Settings)
    MessageBox.Show(Setting);
