Split substring from string and count till next character

I have a string like this ..

2931 8795  012 00:24:14 06/03/13 10:03 O006129009857       **     0           0

Now as per my requirement i have to split the substrings like 2931,06/03/13 and O006129009857.I have used IndexOf method of string to get the start and end index of substring as soon as a empty space comes like this in the code..

 int startIndex = line.IndexOf(Calldate);
 int endIndex = line.IndexOf(" ", startIndex);
 int difference = endIndex - startIndex;
 strSubstring = (startIndex + "," + difference);

As we can see to endIndex i have taken line.IndexOf(" ", startIndex); while now i want to take next character for Example if i have to take O006129009857 then i have to count till ** or any other character available at that place to calculate the endIndex..

Please help me to calculate the endIndex till next character comes instead of . Please help me .Thanks in advance..

It's a little unclear what you are asking but if I understand correctly, you want to calculate the number between a specific index in a string and the next character that is not a space. The following code assumes that you want to know the number of characters between foo and bar but that you know the start index.

string input = "foo     bar";
int startIndex = 3;
string pattern = @"\S";
var regex = new Regex(pattern);
int endIndex = regex.Match(input, startIndex).Index;
int characterCount = endIndex - startIndex;

cant you just use string.Split(' '); to return an array of string that are seperated by a space [" "]?

string CallDate = "2931 8795  012 00:24:14 06/03/13 10:03 O006129009857       **     0           0    ";
string[] parts = CallDate.Split(' ');
parts = parts.Where(s => !string.IsNullOrWhiteSpace(s)).ToArray();

Your parts array looks like

{"2931", "8795", "012", "00:24:14", "06/03/13", "10:03", "O006129009857", "**", "0", "0"}

EDIT: To count the spaces between words, remove the line

parts = parts.Where(s => !string.IsNullOrWhiteSpace(s)).ToArray();

and your array looks like

"2931", "8795", "", "012", "00:24:14", "06/03/13", "10:03", "O006129009857", "", "", "", "", "", "", "**", "", "", "", "", "0", "", "", "", "", "", "", "", "", "", "", "0", "", "", "", ""

The number of empty spaces between each word is the number of empty strings between each non-empty string. a simple for loop over the array will allow you to count the spaces (and therefore the position of each work in the string.

The string.Split function will accomplish this for you:

        string text = "2931 8795  012 00:24:14 06/03/13 10:03 O006129009857       **    0           0";
        char[] Delimiters = new char[]{' '};
        var result = text.Split(new char[]{' '}, StringSplitOptions.RemoveEmptyEntries);

The result will be 2931 8795 012 00:24:14 06/03/13 10:03 O006129009857 ** 0 0
