自己动手写Session

一、首先我们先定义一个方法，用于创建session

public class SessionMsg//创建session { private static IDictionary<string,IDictionary<string,object>> data=new Dictionary<string,IDictionary<string,object>>(); public static IDictionary<string,object> getSession(string sessionId) { if (data.ContainsKey(sessionId)) { return data[sessionId]; } else {  IDictionary<string,object> session=new Dictionary<string,object>(); data[sessionId] = session; return session;

}
}
}

二、然后我们就可以在页面加载事件中使用刚刚创建的session

protected void Page_Load(object sender, EventArgs e)//使用创建好的

{

if (Request.Cookies["sessionId"] ==null)

{

string sessionId = Guid.NewGuid().ToString();

Response.SetCookie(new HttpCookie("sessionId",sessionId));

}

}

protected void Button1_Click(object sender, EventArgs e)

{

string sessionId = Request.Cookies["sessionId"].Value.ToString();

IDictionary<string, object> session = SessionMsg.getSession(sessionId);

session["MySession"] ="设置session的时间是："+DateTime.Now;

}

protected void Button2_Click(object sender, EventArgs e)

{

string sessionId = Request.Cookies["sessionId"].Value;

IDictionary<string, object> session = SessionMsg.getSession(sessionId);

Button2.Text = session["MySession"].ToString();

}

}
