ASP.net 用Image显示图片

现有A页面、B页面。在A页面用FileUpload控件选择图片后传到B页面。B页面用Image控件接收显示A页面传来的图片。如何实现。小弟在此非常感谢！！（不用数据库），呵呵。

Answer 1

a页面
protected void Button1_Click(object sender, EventArgs e)
{
if (FileUpload1.HasFile)
{
string path = Server.MapPath("~\\images\\");
string fileName=FileUpload1.FileName;
FileUpload1.SaveAs(path + fileName);
Response.Redirect("b.aspx?fileName="+fileName);
}
}
b页面
protected void Page_Load(object sender, EventArgs e)
{
if (!string.IsNullOrEmpty(Request.QueryString["fileName"]))
{
string path = "images/";
Image1.ImageUrl = path + Request.QueryString["fileName"];
}
}

a.aspx的C#代码

private void Button1_Click(object sender, System.EventArgs e)
{
Session["Image"] = Image1;
}

b.aspx中C#代码

private void Page_Load(object sender, EventArgs e)
{
Image Image1;
Image1 = （Image）Session["Image"];
}
