如何在C# asp.net的另一页中显示多幅图像
如何在C# asp.net的另一页中显示多幅图像
提问于 2013-12-16 20:27:24
这是我的度假村网页的C#代码。问题是我不能多次显示图像。对于单个图像，这可能是可能的。但在那之后，它就不再起作用了。请帮帮我。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Resorts : System.Web.UI.Page{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
if (DropDownList1.SelectedIndex == 1)
{
Session["room"] = "Deluxe Room";
Label1.Text = "Classy Room";
Label2.Text = "Good for you";
Label3.Text = "100";
Session["rom"] = Session["rom"]+"<br>"+ DropDownList1.Text;
Session["prc"] = Session["prc"]+"<br>"+ Label3.Text;
Session["img"] = Session["img"]+"<br>"+ Image1.Imageurl;
}
else if (DropDownList1.SelectedIndex == 2)
{
Session["room"] = "Deluxe Room";
Label1.Text = "Nga-nga kayo";
Label2.Text = "Good for me";
Label3.Text = "100,000";
Session["rom"] = Session["rom"]+"<br>"+ DropDownList1.Text;
Session["prc"] = Session["prc"]+"<br>"+ Label3.Text;
Session["img"] = Session["img"]+"<br>"+ Image1.Imageurl;
}
}
protected void Button2_Click(object sender, EventArgs e)
{
Response.Redirect("Biodata.aspx");
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
if (DropDownList1.SelectedIndex == 1)
{
Button1.Enabled = true;
Image1.ImageUrl = "~/Styles/Rooms/deluxe1.jpg";
Label1.Text = "";
Label2.Text = "";
Label3.Text = "";
}
else if (DropDownList1.SelectedIndex == 2)
{
Button1.Enabled = true;
Image1.ImageUrl = "~/Styles/Rooms/room2.jpg";
Label1.Text = "";
Label2.Text = "";
Label3.Text = "";
}
else
{
Label1.Text = "";
Label2.Text = "";
Label3.Text = "";
Image1.ImageUrl = "~/Styles/hand.jpg";
Button1.Enabled = false;
}
}
}我用于图像( Session["img"] = Session["img"]+"<br>"+ Image1.Imageurl; )的代码
这就是我希望它显示的页面。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Biodata : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
TextBox1.Text = Session["name"].ToString();
TextBox2.Text = Session["adr"].ToString();
TextBox3.Text = Session["con"].ToString();
TextBox4.Text = Session["email"].ToString();
Label1.Text = Session["rom"].ToString();
Label5.Text = Session["prc"].ToString();
Label4.Text = Session["room"].ToString();
}

在其他页面上尝试此代码。
protected void Page_Load(object sender, EventArgs e)
{
TextBox1.Text = Session["name"].ToString();
TextBox2.Text = Session["adr"].ToString();
TextBox3.Text = Session["con"].ToString();
TextBox4.Text = Session["email"].ToString();
Label1.Text = Session["rom"].ToString();
Label5.Text = Session["prc"].ToString();
Label4.Text = Session["room"].ToString();
string strImageUrls = Convert.ToString(Session["img"]);
string[] arrImageUrls = strImageUrls.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);
if (arrImageUrls != null && arrImageUrls.Length > 0)
{
foreach (string strImageURL in arrImageUrls)
{
//DO your image binding here like
//Image1.ImageUrl = strImageURL ;
}
}
}在按钮单击事件中进行如下更改：
protected void Button1_Click(object sender, EventArgs e)
{
if (DropDownList1.SelectedIndex == 1)
{
Session["room"] = "Deluxe Room";
Label1.Text = "Classy Room";
Label2.Text = "Good for you";
Label3.Text = "100";
Session["rom"] = Session["rom"] + "<br>" + DropDownList1.Text;
Session["prc"] = Session["prc"] + "<br>" + Label3.Text;
Session["img"] = Convert.ToString(Session["img"]) + Image1.Imageurl + ",";
}
else if (DropDownList1.SelectedIndex == 2)
{
Session["room"] = "Deluxe Room";
Label1.Text = "Nga-nga kayo";
Label2.Text = "Good for me";
Label3.Text = "100,000";
Session["rom"] = Session["rom"] + "<br>" + DropDownList1.Text;
Session["prc"] = Session["prc"] + "<br>" + Label3.Text;
Session["img"] = Convert.ToString(Session["img"]) + Image1.Imageurl + ",";
}
