C# searching strings

[patrickcabenjamin]

Hi

In C# i am a complete noob and i know very little, How do you search for a particular word in a string in a console application and make that the value of the string.

for example

System.Console.Out.WriteLine("how are you");
string1 = System.Console.In.ReadLine();
//here it would find if the word good is in string1 but they might have //written i am good
//now string1 would be good rather than i am good
{
System.Console.Out.WriteLine("oh you are " + string1);
}


is this possible? and if so how?

It's possible a couple of different ways, the easiest would be utilizing the built in methods (http://msdn.microsoft.com/en-us/library/system.string_methods.aspx) with the string type (the more advanced and powerful way is via regular expressions (http://msdn.microsoft.com/en-us/library/ms228595(VS.80).aspx)).


System.Console.Out.WriteLine("how are you");
string1 = System.Console.In.ReadLine();
//here it would find if the word good is in string1 but they might have //written i am good
//now string1 would be good rather than i am good
if(string1.ToLower().Contains("good"))
{
string1 = "good";
}
System.Console.Out.WriteLine("oh you are " + string1);
}

what about if i wanted to find the word after "i am" and make that string1?
would that be possible?

You could if you simply found the character location of the match, namely something like

string1.ToLower().Contains("i am") and find the index of the m in "i am", add 1, and voila.

I'm not totally familiar with C#, but it would be possible, easily.

Personally, I'd do a Regex match on "i am" and then grab the group after it, something like say:

/i am([\s\w]*)/

Which should effectively capture any space or word characters proceeding the match of "i am".

Disclaimer: Regex was written on the fly, as a general rule of thumb, you'll never get your Regex right on the first try.

how would you write it out in a script?
