sender As Object,
ByVal e As
System.EventArgs)
Handles Me.Load
If Request.QueryString("num")
IsNot Nothing Then
Dim num As Integer = Integer.Parse(Request.QueryString("num"))
For i As Integer = 1 To
10
Response.Write(i * num & "<br>")
Next
End If
End Sub
C# code
protected void Page_Load(object
sender, EventArgs e)
{
if (Request.QueryString["num"]
!= null)
{
int num=int.Parse(Request.QueryString["num"]);
for
(int i = 1; i <= 10; i++)
Response.Write(i * num+"<br>");
}
}
