Open large document file

[Deegii]

Dear Syncfusion Team,

My Word document files have lots of graphic, images and text, each of size is 20mb and has 600 pages. I tried to open a file according to below codes.   

string wordfilepath = @"D:\Testweb\documents\NSC\NSC_20210503_022113.docx";

           using (FileStream fileStream = new FileStream(wordfilepath, System.IO.FileMode.Open, System.IO.FileAccess.Read))

            {

                WordDocument document = WordDocument.Load(fileStream, ImportFormatType.Docx);

                string json = Newtonsoft.Json.JsonConvert.SerializeObject(document);

                document.Dispose();

                //To observe the memory go down, null out the reference of document variable.

                document = null;

                SfDocumentEditor editor = container.DocumentEditor;

                editor.Open(json);

                //To observe the memory go down, null out the reference of json variable.

                json = null;

            }

But while opening this file, consumption of memory is too high as well as file is not opened. So, How do I open those large files.

Thank you,

Deegii

Hi Deegii, 

Syncfusion Greetings! 

Can you increase maximum length and try importing document? 

For processing the large size documents, we need to configure the MaximumReceiveMessageSize to higher value within ConfigureSerives .  

  

Documentation: https://docs.microsoft.com/en-us/aspnet/core/signalr/configuration?view=aspnetcore-3.0&tabs=dotnet#configure-server-options  

  

Please refer code example required for increasing the message size within ConfigureServices method in Startup.cs file.  

  

          // To increase the size of the buffer    

          services.AddServerSideBlazor().AddHubOptions(o =>  

            {  

                o.MaximumReceiveMessageSize = 102400000;  

            });  

  

  

Kindly revert us if you still facing issues along with the document upon which you face issue. 

Also, Can you please share the details of Blazor approach (Blazor server or Blazor webassembly mode) you are using? 

Regards, 

Suriya M.

Thank you for your response. 

The followings are my codes but results is not comes out

            services.AddServerSideBlazor(options =>

            {

                options.DisconnectedCircuitRetentionPeriod = TimeSpan.FromMinutes(20);

            }).AddHubOptions(x => x.MaximumReceiveMessageSize = 1572864000);

            services.AddSignalR(e => {

                e.MaximumReceiveMessageSize = 1572864000;

            });

.............................

WordDocument document = WordDocument.Load(fileStream, ImportFormatType.Docx);

string json = Newtonsoft.Json.JsonConvert.SerializeObject(document);

I saved json string of only one file into the database,  its around 144Mb. 

How do I open large files. Please give me some idea.

Thank you,

Deegii

Hi Deegii,     

From further validation, Docx file is zip archive file with extension as "docx" Document Editor internally decompresses it and populates the content in the document object and convert it to SFDT and shared to client side for rendering. In the shared document initial file size is 20 MB and the extracted size is 40 MB. We convert the 40 MB contents to the SFDT format expected by the client side. The generated SFDT is around 140 MB and which uses interop methods to pass the string to client side. Here when passing we are facing the disconnection from the interop methods. We are analyzing on the option available to use application level setting and it was not helpful yet. We are exploring if we can try any other alternatives in passing the string to the client. We will share the further analysis details by Aug 4th, 2021.
