and just get the time value appearing after pts_time .

Expected Output :

How to get the expected output?? Any help would be really appreatiated.

Answer 1

Split n:96 pts:341998 pts_time:3.79998 pos:-1 fmt:yuvj420p sar:12/11 with Space.

string[] lineParts = line.Split(" ".ToCharArray());

Get the array element which matches pts_time key.

string ptsTime = lineParts.First(p => p.StartsWith("pts_time")); // pts_time:3.79998

Split the ptsTime with :

string ptsTimeValue = ptsTime.Split(':')[1]; // 3.79998
