NP118 different result

Hi Guys

 

NP118 different result

 

http://www.aspfree.com/c/a/C-Sharp/C-Sharp-FileStream-Explained/3/

 

Following program is given in the above website. When “Start Without Debugging” is used program is producing following result:

 

Investigating the file capabilities

Can Read? True

Can Write? False

Can Seek? True

Before we start reading bytes the current position: 0

After we have read the bytes the current position: 0

 

When “Step Into” (F11) key is used same program is producing different result.  

 

Please explain the reason for the variation.

 

Please tell me how to get the output expected by author.

 

Thank you
