"L24789A-12345Ax.DAT" is this a file name?

IndrajitDasgupat 4-Jul-11 2:24am

its like a string not file name because my client will get it as string only

Solution 4

Try like following code snippet.

C#

string Str = "L24789A-12345Ax.DAT";
string strWithoutExtension = System.IO.Path.GetFileNameWithoutExtension(Str);
string[] splitArray = strWithoutExtension.Split('-');
string firstPart = splitArray[0];
string secondPart = splitArray[1];

It may help you because this solution will be the best by considering performance as well:

static void Main(string[] args)
        {
            string a = "L24789A-12345Ax.DAT";
            string[] b = (a.Replace(".DAT", "")).Split('-');
            Console.WriteLine("first = " + b[0]);
            Console.WriteLine("second = " + b[1]);
            Console.ReadLine();
        }

Right. 5+

Solution 1

Use:

C#

string str="L24789A-12345Ax.DAT"; //for example
//...

string parts[] = str.Split(new char[] {'-', '.'});
//it will give you (with data in your example)
//array with 3 elements: use <code>parts[0]</code> and <code>part[1]</code>;
//they will contain strings you need;
//ignore part[2] where "DAT" is.

What about .DAT because I don't need .DAT so how to remove that from the string

Sergey Alexandrovich Kryukov 5-Jul-11 0:30am

I did not pay attention, sorry. OK, now it is taken into account, please see the updated solution.

You can use substring to remove the dat file and then split it.

Just insert following few lines of code to code provided by SA:

string str="L24789A-12345Ax.DAT"; //for example
int len = str.Length;
string str1 = str.Substring(1, len - 5);
string[] parts = str1.Split(new char[] {'-'});
label1.Text = parts[0];
label2.Text = parts[1];

SO ugly. Why not write code that will return the right value, no matter what ?

Solution 3

I would use regular expressions, as in this case you want to split on one thing, and also remove another. It IS true that Path.GetFilenameWithoutExtension will remove the .DAT for you and you could just split on the - after that.

OK, I would use ([^-]*)-([^.]*).DAT as the regex, and then when you run it, the two captured groups will be the two strings you want. You can replace DAT with something more general to match any filename.

Indeed regex has all the tools in capable hands to chop the strings. +5

I rather recommend an independent solution... so I would also go with the regex.
