How to split the string not use Split function?

Question

I have this parameter below

token[10] ="Date: UTC 2012-02-02 17:09:04"

i wrote the following code to extract only year and month,so it suppose to be "201202". is this anyway i can get only those value with out using split,i know we can use regex too but is this any other way to extract those values

        string Encdate = tokens[10];
        string[] EncdateValue = Encdate.ToString().Split(' ');
        string Encdatesplit = EncdateValue[2].TrimStart();
        string[] YYMM = Encdatesplit.ToString().Split('-');
        string YYMMVal = YYMM[0] + YYMM[1];

Could do a little string manipulation, cast it to a datetime, and then do a formatted .ToString() on it — Stefan H

Why don't you parse the date into a DateTime object and extract the components using the DateTime functions. Get the year and month and concatenate them to get your desired value. — agarcian

Seems that your data is at a fixed position, so why bother with Split() or Date conversion, do a simple Substring() extraction as @keijzers suggest (after replacing token with Encdate) — Steve

Just use DateTime.ParseExact method and access the Year and Month properties from the returned DateTime object, otherwise use Date/Time string formatters and the DateTime.ToString(string) method to get the yyyyMM format, here is an example:

        var d = DateTime.ParseExact(token, "'Date: UTC' yyyy-MM-dd HH:mm:ss", 
                CultureInfo.InvariantCulture, 
                DateTimeStyles.AllowWhiteSpaces | DateTimeStyles.AssumeUniversal);

        Console.WriteLine(d.ToString("yyyyMM"));

var t = token[10];

You also could use a concatenation of the needed characters:

string Encdate = t[10] + t[11] + t[12] + t[13] + t[15] + t[16];

Or use substring (for adding the two):

string Encdate = t.Substring(10, 4) + t.Substring(15, 2);

Or a substring and a remove:

string Encdate = t.Substring(10, 7).Remove(4);

In your question is stated: token ="Date: UTC 2012-02-02 17:09:04"
