Q:

How to set max FileSize of uploaded file with if-statement? 

I created an <asp:fileupload id="FileUploadPassfoto"> on my webpage. ( ASP.NET AND C#)
I want to check if the uploaded file(image) is bigger than 6000KB.  If true, the file wont be accepted and a error message will be displayed.  I stored the uploaded file as following: (CODE BEHIND)
System. Drawing. Image photo = System. Drawing. Image. FromStream(FileUploadPassfoto. PostedFile. InputStream);

Now i want to check if the image is bigger then 6000KB.  
It works with something like photo.size > Size(6000KB).  
Any suggestions? 

A:

You can check like this:
decimal size = Math. Round(((decimal)FileUploadPassfoto. PostedFile. ContentLength / (decimal)1024), 2);
    if(size > 6000)
    {
       // size is greater than 6000KB 
    }
