I have extract the 3 usable field from a string. There is no common delimiter, there can be both blank spaces and tabs.
First, what I am doing is replacing all double blanks and tabs by '**'
Given String :
cont = Gallipelle 04/04/2012 16.03.03 5678
I am using:
cont.Replace(" ", "**").Replace(" ", "**").Replace(" ", "**").Replace("**", "").Trim()
The answer becomes:
****** Gallipelle******04/04/2012 16.03.03************************ 5678*****
Is the approach correct? How do I extract the stuffs from here? I just need all the extracts in string datatype.
Just use String.Split
:
var fields = cont.Split(new[] { " ", "\t" },
StringSplitOptions.RemoveEmptyEntries);
Adding StringSplitOptions.RemoveEmptyEntries
makes sure that if there are multiple consecutive tabs and/or spaces they will "count as one" when extracting the results.
An alternate option would be to use a regular expression.
You can use regex groups to find out three values name, date, number.
A group is defined as (?<group_name><regex_expr>)
So you could write
Regex regex = new Regex("(?<name>(\\S*))(\\s*)(?<date>((\\S*)\\s(\\S*)))(\\s*)(?<number>(\\d*))");
Match match = regex.Match(yourString);
if (match.Success)
{
string name = match.Groups["name"].Value;
string date = match.Groups["date"].Value;
string number = match.Groups["number"].Value;
}
\\s* matches sequence of whitespaces which includes tabs. \\S* matches sequence of non-whitespace characters. \\d* matches sequence of digits.
(new Regex("\\s+")).Split(yourstring)
var myText="cont = Gallipelle 04/04/2012 16.03.03 5678";
var splitString=myText.split(" ");
// splitString[1] == Gallipelle
// splitString[2] == 04/04/2012
// splitString[3] == 16.03.03
// splitString[4] == 5678
No. No need to replace it with any other delimiter. You can use String's split function and give 'space' as delimiter character. eg in VB.Net:
Dim value As String() = cont.split(CChar(" "))
this will give you a string array whose values you can access: value(0), value(1) and value(2)
