String operation

[SRKSHOME]

Hi, I have following string. And I have to extract "931.3392ms" from the string. This line of string is not delimited by any character. How do I extract it? 8 (26/04/2010 05:58.03) Execute(WQADataRequest, WQA_LOAD_TYPE.Deep) 931.3392ms (1.7/11.4 KB)

Are they delimited by spaces? Are there always the same number of elements in your string? If so, you could split[^] it on the space.

This line of string is not delimited by spaces.Yes,this particular line always contains same number of elements. Is there any efficient method other than split?

Try This

string str = "8 (26/04/2010 05:58.03) Execute(WQADataRequest, WQA\_LOAD\_TYPE.Deep) 931.3392ms (1.7/11.4 KB)";

MessageBox.Show(
(((str.Substring(str.IndexOf(")") + 1)).
Substring((str.Substring(str.IndexOf(")") + 1)).IndexOf(")") + 1)).
Substring(0, ((str.Substring(str.IndexOf(")") + 1)).
Substring((str.Substring(str.IndexOf(")") + 1)).IndexOf(")") + 1)).IndexOf("(")))
);

You already mentioned that, just checking since there were spaces in the example-string.

Split on some other character? Like the "("?

But the elements do not always have the same length?

Yup, using regular expressions[^].

I can't disagree more, that is horrible code. It is unreadable, it has 7 calls to IndexOf where you only need 3, and 7 to SubString where you also need just 3.

string a=str.Substring(str.IndexOf(")") + 1);   // skip everything before first ")"
string b=a.Substring(a.IndexOf(")") + 1);       // skip everything before second ")"
string c=b.Substring(0, b.IndexOf("("));        // drop everything after next "("

The Regex alternatives are pretty simple too, here is one; the result excludes the surrounding spaces:

string d=Regex.Match(str, @"\\) (\[0-9\\.\]\*ms) \\(").Groups\[1\].Value;

Use a Regular Expression, check out Expresso[^] or my own RegexTester[^].

+5 for sarcasm.

if the string is always fix size you can simply try the Substring method of the String class.

You may want to consider using my StringParser[^] class.

string mSec = string.Empty;
StringParser sp = new StringParser (s);
if (sp.skipToEndOf (") ") && sp.skipToEndOf (") ")) {
sp.extractTo ("(", out mSec);
}
