String Tokenize

Lam,

If you have just one character that you can split the string on, just
use the Split method on the string instance. If you have more complex
tokenization requirements, then use a regular expression.

Hope this helps.
 
I am new to c# and I am not sure how to use regular expression
I have the line like this

"C 07/18/05 12:01 18002236481 00:04:01 805 130"

how can I put each one into different string variables?
maybe you can give me some hints ?

Thanks a lot

Lam,

Is your delimiter the space character? If so, you can just call the
Split method, like so:

// Split on the space character.
// Assume val stores the string.
string[] strings = val.Split(new char[]{' ', '\t'}, false);

In .NET 2.0, it should be noted that false should be replaced with
StringSplitOptions.None (the overload with the boolean parameter is marked
as obsolete).

To me, it looks like a fixed length or tab-delimited file. But more lines
would be needed to say one way or the other ;)

Thought I'd point that out ;)
