In our .Net 1.1 days we used to check whether a string object contains a specified string(text) using IndexOf method.

Here is the typical code to check the existence of a string in an string object.

//Sample code

string sName = "John Smith";

if(sName.IndexOf("Smith") > -1) {

//Smith exists in string object sName

}

Now let's take a closer look at the above code...... What we want is to know whether an instance of string contains some string(text).

Did I say contains......that's exactly C# .Net 2.0 provides us with.

Let's revisit the same functionality using 2.0

//Sample code 

string sName = "John Smith";

if(sName.Contains("Smith")) {

//Smith exists in string object sName

}

Wallah.....it's so simple and sophisticated.
