When you have several different outcomes, else if becomes a bit cumbersome, but it works fine A better alternative than else if is the switch statement, which can handle any number of conditional values The switch statement takes the value of a single variable and then examines several different cases to decide which to use Most switch statements also contain a break statement at the end so that when the matching case is

The switch statement allows you to easily deal with several conditional values Depending on the case value, you can have your program take a wide range of desired actions This comes in handy when you need to have more than a single or just a few options available to launch One use you can put the switch statement to is in sorting out the outcomes generated by the StringCompare values shown in Table 3-4 Each of the possible three values that the StringCompare method generates is treated as a separate case So the cases would be
case 1: case -1: case 0:
ASPNET 35: A Beginner s Guide
Depending on the case your script generates, the actions have the program do different things The following SwitchCom application provides an example of how to apply the switch statement

C# SwitchCom
using System; public partial class SwitchCompare : SystemWebUIPage { private int n1; protected void DoCompare(object sender, EventArgs e) { //In using StringCompare the following outcomes //are possible: //-1 means that the first string is less than the second //1 means that the second string is less than the first //0 means the values are equal
3: C# and ASPNET 35
n1 = StringCompare(TextBox1Text, TextBox2Text); switch (n1) { case -1: OutputText = TextBox1Text + " is less than " + TextBox2Text; break; case 1: OutputText = TextBox2Text + " is less than " + TextBox1Text; break; case 0: OutputText = "The two strings are identical"; break; } } }
Figure 3-2 shows that two strings with the same casing are resolved as identical However, the output in Figure 3-3 indicates that the first string is less than the second string Note that the only difference between the two is that the first string is all lowercase, and the second string has a single uppercase character In the example, you can see exactly what s going on with the StringCompare method and better use it in your own applications
Loops
Loops generate repeated actions until some condition is met Like most languages, C# has different kinds of loops, depending on the situation of its use Each complete loop is

Similar strings with different cases are resolved as different
called an iteration, and loops can have as many or as few iterations as needed However, you must be careful to have some kind of condition that will terminate the loop Different kinds of loops have different ways of setting up termination conditions, and in the next subsections, you will see the primary loops you ll use in C#
