ViewState的用法

public class People
{
    private string name;
    private int age;
    public People() { }
    public string Name
    {
        get { return name; }
        set { name = value; }
    }
    public int Age
    {
        get { return age; }
        set { age = value; }
    }
}



 protected void Button1_Click(object sender, EventArgs e)
    {
        string txtname = TextBox1.Text;
        int intage = int.Parse(TextBox2.Text);
        People p = new People();
        p.Age = intage;
        p.Name = txtname;
        ViewState["people"] = p;

    }
    protected void Button2_Click(object sender, EventArgs e)
    {
        TextBox1.Text = TextBox2.Text="";
        People pp = (People)ViewState["people"];
        Label1.Text = pp.Name;
        Label2.Text = pp.Age.ToString();
    }
