ASP.NET中有一个FileUpLoad和一个Image控件，怎么样才能使FileUpLoad选择了图片，Image就可以显示出来？

最好添加一个Button按钮，点击该按钮即可将FileUpLoad选择的图片显示在Image控件上；代码如下：protected void Button1_Click(object sender, EventArgs e) { if (FileUpload1.HasFile) { string filename = FileUpload1.FileName; string uploadfilename = Server.MapPath("~/") + filename; FileUpload1.PostedFile.SaveAs(uploadfilename); Image1.ImageUrl = uploadfilename; } }
