序列化与反序列化的初步学习

代码

// 写入文件
FileStream fs = new FileStream( @" E:\TK.txt " , FileMode.Create);
StreamWriter sw = new StreamWriter(fs, System.Text.Encoding.UTF8);
sw.Write( this .TextBox1.Text);
sw.Close();
sw.Dispose();
fs.Close();
// 读取文件
using (FileStream fs = new FileStream( @" F:\Tddd.txt " , FileMode.Open))
{
StreamReader sr = new StreamReader(fs, System.Text.Encoding.UTF8);
this .TextBox2.Text = sr.ReadToEnd();
sr.Close();
sr.Dispose();
}
