Given a folder path in the computer, requiring all the pictures and the name of the file displayed on the web page, what control can i use?

Create A class first .Here i am assuming that your images are located in a directory called Images

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.IO;

/// <summary>
/// Summary description for PhotoManager
/// </summary>
public class PhotoManager
{
	public PhotoManager()
	{
		//
		// TODO: Add constructor logic here
		//
	}
    public FileInfo[] GetFilesInFolder() { 
    
        DirectoryInfo objP =new DirectoryInfo(HttpContext.Current. Server.MapPath("~/Images"));

        FileInfo[] objfileCollection = objP.GetFiles();

        return objfileCollection;
    }

    

        

}

Then place a Data list control on the web form : Some thing look like

<asp:datalist id="DataList1" runat="server" repeatcolumns="4" xmlns:asp="#unknown">
     <itemtemplate>
         <asp:image id="Image1" runat="server" height="50px">
             ImageUrl='<%# Eval("Name","~/Images/{0}") %>' Width="50px" />
     </asp:image></itemtemplate>
 </asp:datalist>

Then place this code in the Code in aspx file:

protected void Page_Load(object sender, EventArgs e)
    {
        DataList1.DataSource = new PhotoManager().GetFilesInFolder();
        DataList1.DataBind();
        

    }

I think this is you are looking
