[nashrahkhan]

My program is working fine. On runtime it gives me the following issue.
“StartIndex cannot be less than zero.\r\nParameter name: startIndex”.
Your assistance is quite appreciable.
Thank you

Can you share some clear info about the issue?

Which activity and some screens of the issue etc.,

Thanks

As there is no compile time error. I am just using switches to move my files to folders.
On runtime it is showing me this error. I don’t know how to resolve this?

@nashrahkhan

The problem is with the substring you are using, can you check once again

Hope this helps you

Thanks

The condition I applied here is “filename.substring(filename.Length-4)”
And I found no issue in this. Can you guide me that how its wrong?

@nashrahkhan

Check as below

If the variable has the value, then what ever you given is fine, check variable is having correct value

Check below if i try to pass the empty value in the string, I got your error

So check the value of the FileName

Hope this clears you

Thanks
