Agenda :
Dear All, In this article I'm demonstrating "Working with file upload control in asp.net – PART - II".Working with FileUpload Control using Asp.Net is quite simple. As per the coding pattern, we can achieve the uploading of files that can be achieved with a lesser number of lines of code which can be demonstrated in the earlier tutorial named "How to work with File upload control using Asp.Net".
However, please be notice that there were few concerns we can even strengthen the earlier implementation with multiple checks so that it should be more qualitative in real-time production environments which can be discussed in this tutorial named as "Working with file upload control in asp.net – PART - II" this example was done with C#.Net using Asp.Net
Description :
In previous articles, I explained different articles related to C#.Net,Asp.Net, SQL Server, XML, and DotNetInterviewQuestions Related articles. Now Let's focus on how to work with File upload control using Asp.Net.
Thinks to be Taken Care in File Upload in Part - II :

Thinks to be Taken Care in File Upload in Part - II :
- We must check the type of file which is being uploaded
- Size of the File which is being uploaded
- So that Junk can be handled before hitting to the server
- The above checks really bring potential value to the implementation. Please be ensure that your application is in specifically dealing with certain types of files for e.g.., jpg/png/doc/Docx/Xls/txt, etc of a certain size
