Deleting a file from the server

hi Everybody,

Some times v may have to replace our old file ( what b the file format) with new one.Just like updating Bio in a job Portal an example. for that v need to find whether it exist a file  On that name if v find. v need to delete it.Some server will done this job automatically some times it may throw an error "Access denied".So let's don't take that risk :)

Binding or display image having zoom effect from folder

Hi *.*,

As a continuation of my previous post. Now i'm binding images from folder.

Code 

    private class ImageFileInfo

    {

        public string FileName { get; set; }

    }

    public void limage()

    {

        string imgFolder = HttpContext.Current.Request.PhysicalApplicationPath + @"img\";

        string[] fileEntries = Directory.GetFiles(imgFolder);

        List<ImageFileInfo> mylist = new List<ImageFileInfo>();

        foreach (string fName in fileEntries)

        {

            string d = System.IO.Path.GetFileName(fName);

            mylist.Add(new ImageFileInfo { FileName = d });

        }

        dtagrid.DataSource = mylist;

        dtagrid.DataBind();

    }

 

On HTML

 

                <asp:DataList ID="dtagrid" runat="server" RepeatColumns="5" RepeatDirection="Horizontal">

                    <ItemTemplate>

                        <li><a href='img/<%# Eval("FileName") %>'>

                            <img src='img/<%# Eval("FileName") %>' alt="" /></a></li>

                    </ItemTemplate>

                </asp:DataList>

Getting File type or Getting file extension

 Getting File type or Getting file extension is done by some many ways a few is listed here ::-

• string fileExtension = System.IO.Path.GetExtension(@"C:\MyFolder\MyFile.jpg") 
• System.IO.FileInfo f = new System.IO.FileInfo(Server.MapPath("~/MyFolder/MyFile.jpg"));
  string extension = f.Extension;

 Over here i prefer the second method.

Stay tune...
