So are you saying that you need code that can convert the string
[00.0%] 0/100 frames, 2.00 fps, 700.07 Kb/s, eta 4:30:00
into the string
00.0 0/100 frames, 2.00 fps, 700.07 Kb/s, eta 4:30:00
String.Replace would be an easy way to do this. But Split could be used. What is the code you have, and what is the error?
Why do you need to do it in one line? That seems like an unnecesary and artificial limitation. If it's really important, put the code in a function - the call tothe function will only take up one line.
