European ASP.NET 4.5 Hosting - UK :: Zip File Manipulation in ASP.NET 4.5

clock December 11, 2014 08:16 by author Scott

One of the missing feature of .NET framework was a support for Zip file manipulation such as reading the zip archive, adding files, extracting files, etc. and we were using some third party libraries such as excellent the DotNetZip. In .NET 4.5, we have an extensive support for manipulating .zip files.

First thing that you should do is to add System.IO.Compression assembly as reference to your project. You may also want to reference System.IO.Compression.FileSystem assembly to access three extension methods (from the ZipFileExtensions class) for the ZipArchive class: CreateEntryFromFile,CreateEntryFromFile, and ExtractToDirectory. These extension methods enable you to compress and decompress the contents of the entry to a file.

Let’s cover the bits and pieces that we get from System.IO.Compression assembly at first. The below sample shows how to read a zip archive easily with ZipArchive class:

static void Main(string[] args) {

    const string zipFilePath = @"C:\apps\Sample Pictures.zip";

    using (FileStream zipFileToOpen = new FileStream(zipFilePath, FileMode.Open))
    using (ZipArchive archive = new ZipArchive(zipFileToOpen, ZipArchiveMode.Read)) {

        foreach (var zipArchiveEntry in archive.Entries)
            Console.WriteLine(
                "FullName of the Zip Archive Entry: {0}", zipArchiveEntry.FullName
            );
    }
}

In this sample, we are opening the zip archive and iterate through the collection of entries. When we run the application, we should see the list of files inside the zip archive:

It’s also so easy to add a new file to the zip archive:

static void Main(string[] args) {

    const string zipFilePath = @"C:\apps\Sample Pictures.zip";

    using (FileStream zipFileToOpen = new FileStream(zipFilePath, FileMode.Open))
    using (ZipArchive archive = new ZipArchive(zipFileToOpen, ZipArchiveMode.Update)) {

        ZipArchiveEntry readMeEntry = archive.CreateEntry("ReadMe.txt");
        using (StreamWriter writer = new StreamWriter(readMeEntry.Open())) {
            writer.WriteLine("Lorem ipsum dolor sit amet...");
            writer.Write("Proin rutrum, massa sed molestie porta, urna...");
        }

        foreach (var zipArchiveEntry in archive.Entries)
            Console.WriteLine(
                "FullName of the Zip Archive Entry: {0}", zipArchiveEntry.FullName
            );
    }
}

In this sample, we are adding a file named ReadMe.txt at the root of archive and then we are writing some text into that file.

Extracting files is into a folder is so easy as well. You need reference the System.IO.Compression.FileSystem assembly along with System.IO.Compression assembly as mentioned before for this sample:

static void Main(string[] args) {

    const string zipFilePath = @"C:\apps\Sample Pictures.zip";
    const string dirToExtract = @"C:\apps\Sample Pictures\";

    using (FileStream zipFileToOpen = new FileStream(zipFilePath, FileMode.Open))
    using (ZipArchive archive = new ZipArchive(zipFileToOpen, ZipArchiveMode.Update))
        archive.ExtractToDirectory(dirToExtract);
}

There are some other handy APIs as well but it is so easy to discover them by yourself.

ASP.NET 4.5 offer many great feature. Previously, we have discussed about one of new feature on ASP.NET 4.5, Key HTML Editor Features in ASP.NET 4.5. In today post, we will discuss about how to use ListView Control in ASP.NET 4.5

ASP.NET ListView Control has a great features that GridView and Repeater controls had control over the markup. The ListView Control allows you to display the data in various formats including grid format, bulleted list format and in flow format.

How to Insert and Delete Data with the ListView Control

OK, let’s get started

1. Drag the ListView control from data category of the toolbox to default.aspx page and choose the datasource for the control as shown below

2. Configure ListView option from ListViewControl smart tags as shown below

Provide the template information by selecting the desired template and also it allows you to select style for control. It also allows you to enable operations such as inserting and updating.

3. Add some custom styling to the control by adding a class as shown below

<LayoutTemplate>
            <ul id="itemPlaceholderContainer" runat="server" class="ItemStyle">
                <li runat="server" id="itemPlaceholder" />
            </ul>
</LayoutTemplate>

4. Remove the Id columns from ItemTemplate as these mark-ups generated automatically when you configure the control and columns. Repeat the same for InsertItemTemplate.

5. Add the custom styles to item containers as below

.ItemStyle
{
  width: 800px;
  list-style-type:none;
  clear:both;
}

.ItemStyle li
