spr矉: Could not read block - no data!

[C_disposable]

This error has been showing up seemingly randomly but always on the line where I load from an input file. The input file is an .xlsx format as I do input validation to ensure this, wondering if there is any fix or update being worked on, as the only post I saw regarding something similar was back a few years ago and was marked as fixed in version 6 or so.


Input Data: I have tested this with blank sheets, sheets with 100 lines and sheets with 2000 lines, all produce the same error periodically

Code:

Code: Select all

//Create a Workbook object
Workbook workbook = new();

//Load the file stream
workbook.LoadFromFile(inFile);


Using FreeSpire.XLS 14.2.0 installed as a nuget package in visual studio

My environment is Win 11 64bit, EN-GB

My application type is an asp.net core (MVC) web app using .NET 6.0

Hi, As I had stated in my post, I had tried with a blank xlsx document which had thrown the same error.

Also the chance that the error gets thrown seems to be around 2 in 10 approx

But as per your request here is a blank sheet.

Hello,

Thank you for your feedback.
I am still unable to reproduce your issue using the document you provided. Are you loading multiple different documents using multi-threading? First, I recommend that you use our latest commercial version for testing (Spire.XLS for .NET :14.9.1) as the commercial version contains more fixes than the free version. If the issue persists after testing with the latest commercial version, please provide us with a project that can reproduce the problem. You can upload here or send it to us via email (support@e-iceblue.com). Thank you in advance.
