ASP now supports two languages C # ("C Sharp"), Visual Basic, and JScript.
Based on habits, in the following language introduction, we use the practice and routines to develop web applications with VB and C # languages. If you want to get more information about .NET technology, please go to MS Sites to view about NGWS SDK!
In the list below, you can see a brief introduction to the syntax of these two languages
Variable reputation
C # syntax
INT X;
String S;
String S1, S2;
Object O;
Object obj = new object ();
Public String Name;
VB grammar
DIM X as integer
DIM S As String
DIM S1, S2 AS STRING
Dim o 'Implicitly Object
DIM OBJ AS New Object ()
Public Name As String
2 statement
C #:
Response.write ("Tofu");
VB:
Response.write ("Tofu")
3. Notes statement
// Tofu production, is a boutique
/ *
Tofu making
,
Both is boutique
* /
VB:
'Tofu production, all of the boutique
'Tofu making
',
'Is a boutique
4. Get the variable transferred by the URL
C #:
String s = request.QueryString ["name"];
String value = Request.cookies ["key"];
VB:
DIM S, Value As String
s = Request.QueryString ("Name")
Value = Request.Cookies ("key"). Value
5. Declare attribute
C #:
PUBLIC STRING name {
Get {
...
Return ...
}
SET {
... = Value;
}
}
VB:
Public Property Name As String
Get
...
Return ...
END GET
Set
... = Value;
End set
End Property
6. array
C #
String [] a = new string [3];
a [0] = "1";
a [1] = "2";
a [2] = "3";
//Two-dimensional array
String [] [] a = new string [3] [3];
a [0] [0] = "1";
a [1] [0] = "2";
a [2] [0] = "3";
VB:
DIM A (3) AS STRING
a (0) = "1"
A (1) = "2"
A (2) = "3"
DIM A (3, 3) AS String
A (0, 0) = "1"
A (1,0) = "2"
A (2,0) = "3"
DIM A () AS STRING
A (0, 0) = "1"
A (1,0) = "2"
A (2,0) = "3"
Dim A (,) AS STRING
A (0, 0) = "1"
A (1,0) = "2"
A (2,0) = "3" 7 variable initialization
C #:
String s = "Hello World";
INT i = 1
Double [] a = {3.00, 4.00, 5.00};
VB:
DIM S as string = "Hello World"
DIM i as integer = 1
DIM A () as double = {3.00, 4.00, 5.00}
8; judgment statement (IF statement)
IF (Request.QueryString! = null) {
...
}
VB:
If not (Request.QueryString = NULL)
...
END IF
9. Branch statement (CASE statement)
C #:
Switch (firstname) {
Case "john":
...
Break;
Case "Paul":
...
Break;
Case "rinco":
...
Break;
}
VB:
SELECT (FirstName)
Case "john":
...
Case "Paul":
...
Case "rinco":
...
End SELECT
10 for loop statement
C #
For (int i = 0; i <3; i )
A (i) = "test";
VB:
DIM I as integer
For i = 0 TO 2
A (i) = "test"
NEXT
11 While cycle
C #:
INT i = 0;
While (i <3) {
Console.writeline (i.tostring ());
i = 1;
}
VB:
DIM I as integer
I = 0
Do While i <3
Console.writeLine (I.ToString ())
I = i 1
Loop
12 string connection
C #:
String S1;
String S2 = "Hello";
S2 = "world";
S1 = S2 "!!!";
VB:
DIM S1, S2 AS STRING
S2 = "Hello"
S2 & = "world"
S1 = S2 & "!!!"
Declaration event
C #:
Void MyButton_Click (Object Sender,
Eventargs e) {
...
}
VB:
Sub mybutton_click (sender as object,
E as eventargs)
...
End Sub
13 Declaration Object
C #
MyObject obj = (myObject) session ["Some Value"];
IMyObject IOBJ = OBJ
VB:
DIM BJ As myObject
DIM IOBJ AS IMYOBJECT
Obj = session ("Some Value")
IObj = ctype (obj, iMyObject)
14 data type conversion
C #
INT i = 3;
String s = i.to.tostring ();
Double d = double.parse (s);
VB:
DIM I as Integerdim S as String
DIM D As Double
i = 3
s = i.tostring ()
D = CDBL (s)
15 categories of statements and inheritance
C #:
Using system;
Namespace myspace {
PUBLIC CLASS foo: bar {
INT X;
Public foo () {x = 4;
Public void add (int x) {this.x = x;}
Public int GetNum () {Return X;
}
}
VB:
Imports system
Namespace MySpace
Public Class Foo: Inherits Bar
DIM X as integer
Public Sub New ()
Mybase.new ()
X = 4
End Sub
Public Sub Add (x as integer)
Me.x = me.x x
End Sub
Public function getnum () AS Integer
Return X
END FUNCTION
END CLASS
End Namespace
16 statement of the main function
C #:
Using system;
Public class consolecs {
Public consolecs () {
Console.writeline ("Object Created");
}
Public static void main (String [] args) {
Console.writeline ("Hello World");
Consolecs ccs = new consolecs ();
}
}
VB
Imports system
Public Class Consolevb
Public Sub New ()
Mybase.new ()
Console.writeLine ("Object Created")
End Sub
Public Shared Sub Main ()
Console.Writeline ("Hello World")
DIM CVB As ConsolevB
CVB = new consolevb ()
End Sub
END CLASS
17 standard module
C #
Using system;
Public class module {
Public static void main (String [] args) {
Console.writeline ("Hello World");
}
}
VB:
Imports system
Public module consolevb
Public Sub Main ()
Console.Writeline ("Hello World")
End Sub
End module
This article is translated by an English article. From this, we can see MS how much effort is spent in order to rule Web programming.
He completely redefines all the specifications for web programming, making web programming more simple and powerful!
Now you can download the ASP interpreter on the MS site, but too big! Tofu is not downloaded, which friend has this ability, download it, one read as fast!
By the way, introduce you to a better site to learn ASP ! Unfortunately, there is only English! I will translate as many articles as possible in the right time!
The URL of the site is:
Http://tutorial.supeRexpert.com/quickstart/aspplus/doc/langsupport.aspx has another
Http://www.15seconds.com also has an article about ASP
