asp+语法介绍(一)(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

case "Paul" :
...
break;
