So get the IndexOf "find string" and SubString.

Solution 3

Hi chetan,

Firtly - Both the first solutions are of great for your simple purpose.
I want to suggest however, that you learn a bit about Regular Expressions, those will prove extremely useful for search purposes, and are basically a must tool for developers.

See a little example:

C#

string TheText = "Here comes your bulk of text with the pattern to find.";
string WhatToFind_Pattern = "the pattern to find"; // all you have to do is learn some Regex Expressions (see links below the code block ;)
if (System.Text.RegularExpressions.Regex.IsMatch(TheText, WhatToFind_Pattern, System.Text.RegularExpressions.RegexOptions.IgnoreCase))
{
   // Do Stuff
}

Useful links in case you want to get into Regex:

- Validation with Regular Expressions Made Simple[^]
- Regex Quick Reference[^]

Cheers,
Edo

This is a good case for study, i don't think its the best to do this for this specific use. If i had a verified email i may gave you stars. :P

Solution 2

string a = "asdfghijklmnopqrstuvxz";
string b = "hijklm";
bool c = (a.IndexOf(b) > -1);

Solution 1

C#

string a = "this is a string";
string b = "is a";

bool isBinA = a.contains(b);

isBinA will be true in this situation.
