You cannot use the switch statement in ASP, you need to use the Select Case statement
A Brief introduction
Select the work of the report, if the statement. The difference, however, is that they can check for multiple values. Of course, you haveMany of the same, if. Else statement, but this is not always the best method.The SELECT statement allows a program to evaluate the expression and attempt to match t

If statements process two branches, the if-else-if structure must be used when processing multiple branches. However, if there are many branches, the more nested if statement layers, the program is not only huge but also difficult to understand. therefore, the C language provides a condition selection statement speci
Grammarsyntax for switch statements in the Swift language:
Copy Code code as follows:
Switch Expression {
Case expression1:
Statement (s)
Fallthrough/* Optional *
Case Expression2, Expression3:
Statement (s)
Fallthrough/* Optional *
Default:/* Optional *statement (s);}
Note: In most
Switch statements in PHP are used to perform different actions based on multiple different conditions. If you want to selectively execute one of several blocks of code, use a Switch statement.
Switch syntax
The code is as follows
Copy Code
switch (expression)//Set expression{
$a=5;switch($a){ case 6: echo "\$a is 6"; case 5: echo "\$a is 5"; case 4: echo "\$a is 4";}
As in the above example, my understanding is that each time $ A is compared to the value of the case, the output statement is the same, and the non-conformance is the nex

Switch case is a qualified data in js, which is much simpler than if else. Next I will introduce my understanding of js switch case.
In the if Condition Statement, only one logical condition can exist. if multiple conditions exist, you can use nested if statements to solve the problem. However, this method increases th

Default is to execute it if it is not matched, and default is not necessary.The statement after the

In the C ++ programming language, some judgment statements exist, such as the if and C ++ switch-case statements. In this article, we will introduce the basic usage of the C ++ switch-case statement in detail, hoping to help you.

I don't know when the switch-case statement is synonymous with the bad taste of the Code. When I write the code, I carefully avoid it and frown when I see the switch-case in other people's code, think about it. The switch
The switch in Swift has been greatly improved in comparison with this part of the objective-c. This is a very interesting thing, because it is still not added to the objective-c, or the fact that the objective-c is a superset of C is not broken.
The first exciting place is that you can convert to a string. This may be what you want to do, but you can't do. In Objective-c, if you want to use a "switch" to a
Swift can match the values of different data types in the switch:
var things = any[] () things.append (0) things.append (0.0) things.append (a) things.append (3.14159) things.append ("Hello ") Things.append ((3.0, 5.0)) Things.append (Movie (name:" Ghostbusters ", Director:" Ivan Reitman ")) for thing in things {SW Itch Thing {case 0 as int:println (' zero as an Int ')
The Switch...case statement in Swift can determine the object type, and the objective-c must be an integer.Can not penetrate, can not write break,
var rank = "A"
switch rank{case
"a"://equivalent to if
print ("excellent") Case
"B"://equivalent to else if
In other languages, the switch statement is probably like thisSwitch (VAR){Case VALUE1:DO_SOME_STUFF1 ();Case VALUE2:DO_SOME_STUFF2 ();...Case VALUEN:DO_SOME_STUFFN ();Default:do_default_stuff ();}Python itself does not have a switch statement, the solution has the following
The switch can only compare values or characters, but do not think that it is not useful if so. If appropriate, it is more efficient than if Else. The syntax structure of the switch is as follows:
Switch (variable name or expression ){
Case must contain numbers or characters:
Statement 1;
break;
In summary, the use of switch is to determine if the expression after the case matches the expression after switch, and once the case is matched, the subsequent program code is executed, regardless of whether the following case matches until the break was met . Do not match
