Question

I have the following string which i would like to retrieve some values from:

============================
Control 127232:
map #;-
============================
Control 127235:
map $;NULL
============================
Control 127236:

I want to take only the Control . Hence is there a way to retrieve from that string above into an array containing like [127232, 127235, 127236]?

Answer 1

try this (assuming your string is named s and each line is made with \n):

List<string> ret = new List<string>();
foreach (string t in s.Split('\n').Where(p => p.StartsWith("Control")))
    ret.Add(t.Replace("Control ", "").Replace(":", ""));

ret.Add(...) part is not elegant, but works…

EDITED:
If you want an array use string[] arr = ret.ToArray();

SYNOPSYS:
I see you’re really a newbie, so I try to explain:

• s.Split('\n') creates a string[] (every line in your string)
• .Where(...) part extracts from the array only strings starting with Control
• foreach part navigates through returned array taking one string at a time
• t.Replace(..) cuts unwanted string out
• ret.Add(...) finally adds searched items into returning list
