我正在使用一个简单的数据表来显示文件夹中的图像…

在数据列表中点击破碎图像图标后显示错误，无法找到资源。

所有路径定义都应该以~/:

protected void upload_Click(object sender, EventArgs e)
{
    string filename = Path.GetFileName(FileUpload1.PostedFile.FileName);
    FileUpload1.SaveAs(Server.MapPath("~/Images/"+Model.Text+"/" + filename));
    BindDataList();
}
protected void newfolder_Click(object sender, EventArgs e)
{
    string NewDirectory = Server.MapPath("~/Images/"+Model.Text);
    //New Directory Name in string variable
    CreateDirectoryIfNotExists(NewDirectory);
    //Calling the function to create new directory
}

试试这个:

protected void BindDataList()
{
    var imgDir = HttpContext.Current.Server.MapPath(string.Format(@"~/Images/{0}/", Model.Text));
    DirectoryInfo dir = new DirectoryInfo(imgDir);
    FileInfo[] files = dir.GetFiles();
    ArrayList listItems = new ArrayList();
    foreach (FileInfo info in files)
    {
        listItems.Add(info);
    }
    DataList1.DataSource = listItems;
    DataList1.DataBind();
}
protected void upload_Click(object sender, EventArgs e)
{
    string filename = Path.GetFileName(FileUpload1.PostedFile.FileName);
    var imgPath = HttpContext.Current.Server.MapPath(string.Format(@"~/Images/{0}/{1}", Model.Text, filename));
    FileUpload1.SaveAs(imgPath);
    BindDataList();
}
protected void newfolder_Click(object sender, EventArgs e)
{
    var imgDir = HttpContext.Current.Server.MapPath(string.Format(@"~/Images/{0}/", Model.Text));
    //New Directory Name in string variable
    CreateDirectoryIfNotExists(imgDir);
    //Calling the function to create new directory
}
