LoadFromFile returns an error over 4MB

[adrianchan]

Hello,

When I am calling the LoadFromFile function with a word document over 4MB in size, it returns a System.OutOfMemoryException and I was wondering if there were any alternatives to this function e.g. multi-threading since I have tried both methods with different parameters. Any help would be appreciated.

Kind regards,
Adrian

Hello Marcia,

Here is the requested information:
1) .Net 4.8
2) MVC asp.net
3) Win10 64 bit, Hong Kong SAR - Chinese
4) FreeSpire.Doc 9.9.7

With regards to the input file, the problem persists in the fact that we are trying to generate several batches of document, which resulted in having to call the read/ write function recursively, which inevitably leads to memory leak.

Code: Select all

foreach(KeyValuePair<string, Document> entry in dictionary){
   ...
   saveDoc.LoadFromFile(path);
   foreach(Section sec in entry.Value.Sections) {
      saveDoc.Sections.Add(sec.Clone());
   }
   saveDoc.SaveToFile(path, FileFormat.Docx);
   saveDoc.Close();
   }
}


Kind regards,
Adrian

Hello Adrian,

Thanks for sharing more information!

I simulated a project as the information you provided, and then load 4 files, each file is larger than 4MB, but still cannot reproduce your issue. Here are some methods for your try. First, please use document.Dispose(); to release the memory our product use after you finishing save. Or you can also change the solution platforms to X64, since x64 allows more memory space.

Besides, according to your code, do you want to merge two files to one document? If so, you can also use document.InsertTextFromFile("filepath", FileFormat.Docx); or document.InsertTextFromStream(stream, FileFormat.Docx); to achieve your needs.

If the issue still exists after trying these methods, I am afraid that this issue may relate to your input files. Please provide them to us for further investigate, we promise to keep your documents confidential, and we will not use it for any other purpose. Also, you could remove the security data of your Word as long as the modified files could reproduce your issue. Thanks in advance.
