问题描述

大家好，



我尝试使用c＃在asp.net中的运行时按钮点击事件中绑定图像。你可以请任何人帮忙，我的代码在哪里。



代码背后：

Hi All,

I try to bind image in runtime button click event in asp.net with c#. Could you please anyone help and where am dmistake on my code.

Code Behind:

protected void Button1_Click(object sender, EventArgs e)
{
    //if (FileUpload1.HasFile)
    //{
    //    string fileName = FileUpload1.FileName;
    //    FileUpload1.PostedFile.SaveAs(Server.MapPath("~/Images/") + fileName);
    //}
    LoadImages();
//    Response.Redirect("~/TestApp.aspx");
}

private void LoadImages()
{
    string filepath = @"C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures\";
  //  string filepath = "~/Images";
    string[] fileEntries = Directory.GetFiles(filepath, TextBox1.Text + "*.jpg", SearchOption.TopDirectoryOnly);
    foreach (string filename in fileEntries)
    {
        ImageButton imagebutton = new ImageButton();
        FileInfo fi = new FileInfo(filename);
        imagebutton.ImageUrl = filepath + fi.Name;
        imagebutton.AlternateText = fi.Name;
        imagebutton.Height = Unit.Pixel(100);
        imagebutton.Style.Add("padding", "5px");
        imagebutton.Width = Unit.Pixel(100);
        imagebutton.Click += new ImageClickEventHandler(imageButton_Click);
        imagebutton.Visible = true;
        this.Controls.Add(imagebutton);

        Panel1.Controls.Add(imagebutton);
    }

    //foreach (string strfile in Directory.GetFiles(Server.MapPath("~/Images")))
    //{
    //    ImageButton imageButton = new ImageButton();
    //    FileInfo fi = new FileInfo(strfile);
    //    imageButton.ImageUrl = "~/Images/" + fi.Name;
    //    imageButton.Height = Unit.Pixel(100);
    //    imageButton.Style.Add("padding", "5px");
    //    imageButton.Width = Unit.Pixel(100);
    //    imageButton.Click += new ImageClickEventHandler(imageButton_Click);
    //    Panel1.Controls.Add(imageButton);
    //}
}

protected void imageButton_Click(object sender, ImageClickEventArgs e)
{
    Response.Redirect("WebForm1.aspx?ImageURL=" + ((ImageButton)sender).ImageUrl);
}

设计代码：

Design Code:

<form id="form1" runat="server">
    <div>

        <%--<asp:Label ID="Label1" runat="server" Text="FileNames"></asp:Label>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
        <asp:LinkButton ID="LinkButton1" runat="server">LinkButton</asp:LinkButton>--%>
        <%--<asp:FileUpload ID="FileUpload1" runat="server" />--%>
        <asp:TextBox ID="TextBox1" runat="server" />
<asp:Button ID="imagebutton_Click" runat="server" Text="Upload" OnClick="Button1_Click" />
<asp:Panel ID="Panel1" runat="server" Width="440px"

    BorderStyle="Dotted" BorderColor="#000066">
    </asp:Panel>
    </div>
    </form>

推荐答案

在这个问题上可能是图像路径



用户Server.MapPath分配图像路径。

还有一件事将图像文件夹放在你的项目中然后分配路径



假设你有一个image-> userimage文件夹



string filepath =images / userimage;



string [] fileEntries = Directory.GetFiles（ Server.MapPath（filepath），TextBox1.Text +* .jpg，SearchOption.TopDirectoryOnly）;

In this problem may be the image path

user Server.MapPath to assign the image path.
and one more thing put the image folder in your project and then assign the path

suppose you have a image->userimage folder

string filepath="images/userimage";

string[] fileEntries = Directory.GetFiles(Server.MapPath(filepath), TextBox1.Text + "*.jpg", SearchOption.TopDirectoryOnly);
