How to display prime numbers between 1 to 100 in asp.net

In this article I am going to explain how to display prime numbers between 1 to 100 in asp.net

A number is prime if it is divisible only by one and itself. Number two is the only even and also the smallest prime number.

Implementation:

C# code:

protected void Page_Load(object sender, EventArgs e)

    {

        GetPrimenumber();

    }

    public void GetPrimenumber()

    {

        try

        {

            bool CheckPrime = true;

            for (int i = 2; i <= 100; i++)

            {

                for (int p = 2; p <= 100; p++)

                {

                    if (i != p && i % p == 0)

                    {

                        CheckPrime = false;

                        break;

                    }

                }

                if (CheckPrime)

                {

                    Response.Write(i + "<br/>");

                }

                CheckPrime = true;

            }

        }

        catch(Exception ex)

        { }

    }

VB.net code:

Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load

        GetPrimenumber()

    End Sub

    Public Sub GetPrimenumber()

        Try

            Dim CheckPrime As Boolean = True

            For i As Integer = 2 To 100

                For p As Integer = 2 To 100

                    If i <> p AndAlso i Mod p = 0 Then

                        CheckPrime = False

                        Exit For

                    End If

                Next

                If CheckPrime Then

                    Response.Write(i + "<br/>")

                End If

                CheckPrime = True

            Next

        Catch ex As Exception

        End Try

    End Sub
