How to save multiple Word documents as one Zip file in ASP .NET MVC DocIO?

Syncfusion® Essential® DocIO is  ASP.NET MVC Word feature tour page used to create, read, and edit Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can download multiple Word document files as one ZIP file.

Steps to download multiple Word files as one ZIP file programmatically:

1. Create a new ASP.NET MVC application project.
   
2. Install the Syncfusion.DocIO.AspNet.Mvc5 NuGet package as a reference to your .NET Framework applications from NuGet.org.
   
3. A default controller with name HomeController.cs gets added on the creation of ASP.NET MVC project. Include the following namespaces in the HomeController.cs file.

C#

using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;
using Syncfusion.Compression.Zip;

VB.NET

Imports Syncfusion.DocIO
Imports Syncfusion.DocIO.DLSImports Syncfusion.Compression.Zip

4. A default action method named Index will appear in HomeController.cs. Right-click this action method and select Go To View, where you will be directed to its associated view page Index.cshtml.
5. Add new button in Index.cshtml as follows.

   @{Html.BeginForm("CreateDocument", "Home", FormMethod.Get);
       {
           <div>
               <label>
                   Click the button to view the generated Word document.
               </label>
           </div>
           <div>
               <input type="submit" value="Create Document" style="width:150px;height:27px" />
           </div>
       }
       Html.EndForm();
   }
   

6. Add a new action method named CreateDocument in HomeController.cs and include the following code snippet to download multiple Word files in zip format in the browser.

C#

//Create zip file
ZipArchive zipArchive = new ZipArchive();
//Set compression level for new items
zipArchive.DefaultCompressionLevel = Syncfusion.Compression.CompressionLevel.Best;
string[] files = Directory.GetFiles(Server.MapPath("/App_Data"));
for (int i = 0; i < files.Length; i++)
{
//Load an existing Word document
WordDocument document = new WordDocument(files[i], FormatType.Docx);
//Save the document
MemoryStream stream = new MemoryStream();
document.Save(stream, FormatType.Docx);
//Add the files you want to zip
zipArchive.AddItem("Files" + i + ".docx", stream, false, FileAttributes.Normal);
//Close the document.
document.Close();
}
//Zip the filename
MemoryStream memoryStream = new MemoryStream();
zipArchive.Save(memoryStream, false);
return File(memoryStream.ToArray(), "application/zip", "Attachments.zip");

VB.NET

'Create zip file
Dim zipArchive As ZipArchive = New ZipArchive()
'Set compression level for new items
zipArchive.DefaultCompressionLevel = Syncfusion.Compression.CompressionLevel.Best
'Get the files
Dim files() As String = Directory.GetFiles(Server.MapPath("/App_Data"))
Dim i As Integer = 0
Do While (i < files.Length)
'Load an existing Word document
Dim document As WordDocument = New WordDocument(files(i), FormatType.Docx)
'Save the document
Dim stream As MemoryStream = New MemoryStream
document.Save(stream, FormatType.Docx)
'Add the files you want to zip
zipArchive.AddItem(String.Concat(i, ".docx"), stream, False, FileAttributes.Normal)
'Close the document
document.Close()
i = (i + 1)
Loop
'Zip the filename
Dim memoryStream As MemoryStream = New MemoryStream()
zipArchive.Save(memoryStream, False)
Return File(memoryStream.ToArray(), "application/zip", "Attachments.zip")
