基于习惯，在以下的语言介绍中，我们采用的练习和例程采用VB和C#语言来开发Web应用程序.如果想要得到关于.Net技术的详细资
料，请去MS的站点 查看关于 NGWS SDK!
在下面的列表中，你可以看到关于这两种语言的语法的简要介绍
1.变量声名
C# 语法
int x;
String s;
String s1, s2;
Object o;
Object obj = new Object();
public String name;
VB语法
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语句
C#:
Response.Write("豆腐");
VB:
Response.Write("豆腐")
3.注释语句
//豆腐制作，都是精品
/*
豆腐制作
，
都是精品
*/
VB:
'豆腐制作，都是精品
' 豆腐制作
'，
'都是精品
4.获得URL 传递的变量
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.声明属性
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.数组
C#
;;;;String[] a = new String[3];
;;;;a[0] = "1";
;;;;a[1] = "2";
;;;;a[2] = "3";
;;;;//二维数组
;;;;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变量初始化
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;判断语句(If 语句)
if (Request.QueryString != null) {
;;...
}
VB:
If Not (Request.QueryString = Null)
;;...
End If
9.分支语句(case 语句)
C#:
switch (FirstName) {
;;case "John" :
;;;;...
;;;;break;
;;case "Paul" :
;;;;...
;;;;break;
;;case "Ringo" :
;;;;...
;;;;break;
}
VB:
Select (FirstName)
;;case "John" :
;;;;...
;;case "Paul" :
;;;;...
;;case "Ringo" :
;;;;...
End Select
10 For循环语句
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 循环
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 字符串连接
C#:
String s1;
String s2 = "hello";
s2 += " world";
s1 = s2 + " !!!";
VB:
Dim s1, s2 As String
s2 = "hello"
s2 &= " world"
s1 = s2 & " !!!"
声明事件
C#:
void MyButton_Click(Object sender,
;;;;EventArgs E) {
...
}
VB:
Sub MyButton_Click(Sender As Object,
;;;;E As EventArgs)
...
End Sub
13 声明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 数据类型转换
C#
int i = 3;
String s = i.ToString();
double d = Double.Parse(s);
VB:
Dim i As Integer
Dim s As String
Dim d As Double
i = 3
s = i.ToString()
d = CDbl(s)
15 类的声明和继承
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 声明类的主函数
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 标准模块
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
本篇文章是由一篇英语的文章翻译来的，从这里面我们可以看到MS 为了统治Web编程领域，花费了多大的心思！
他完全的重新定义了Web编程的全部规范，使得Web编程变的更加简单和功能强大！
现在在MS 的站点上已经可以 下载 asp+ 的解释器，但是太大！豆腐没有下载，哪位朋友有这个能力，下载下来，一读为快！
顺便给大家介绍一个学习 Asp+ 的比较好的站点！只可惜 目前只有;;英文的！我会在 适当 的时间里，给大家;;翻译;;尽可能;;
多的文章！
站点的 URl是:
http://tutorial.superexpert.com/quickstart/aspplus/doc/langsupport.aspx
还有一个
http://www.15seconds.com也有关于 Asp+ 的文章
