This is the small But useful thing to remember.
We used to check whether a string object contains a specified string(text) using Index Of method.
We used to check whether a string object contains a specified string(text) using Index Of method.
Here is the typical code to check the existence of a string in an string object.
//Sample code
string sName = "Hello Nilay";
if(sName.IndexOf("Nilay") > -1)
{
//Nilay 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 = "Hello Nilay";
if(sName.Contains("Nilay"))
{
//Nilay exists in string object sName
}
