namespace WindowsFormsApplication1

public partial class Form1 : Form

private string m_strXML = "";
// 将⼆维数组序列化成XML
private void button1_Click(object sender, EventArgs e)
{
string[][] str = { new string[] { "1","2","3" }, new string[] { "A","B","C" } };
XmlSerializer xml = new XmlSerializer( str.GetType() );
System.IO.MemoryStream ms = new System.IO.MemoryStream();
XmlTextWriter writer = new XmlTextWriter(ms, Encoding.Default);
xml.Serialize(writer, str);
// 得到序列化后的XML字符串，可以直接保存到数据库
m_strXML = Encoding.Default.GetString(ms.ToArray());
MessageBox.Show(m_strXML);
}
// 把XML反序列化为⼆维数组
private void button2_Click(object sender, EventArgs e)
{
// 从数据库取出XML字符串，这⾥使⽤m_strXML变量
XmlSerializer xml = new XmlSerializer( typeof(string[][]) );
StreamReader sr = new StreamReader(new MemoryStream(System.Text.Encoding.Default.GetBytes(m_strXML)), System.Text.Encoding.Default);            string[][] str=(string[][])xml.Deserialize(sr);
foreach (string[] s1 in str)
typeof array{
foreach (string s2 in s1)
{
MessageBox.Show(s2);
}
}
}
