Introduction
Today, in
this blog let's play around with one of the interesting and most useful
concept in C#.
Question: What
is math class?
In simple
terms "It provides rich set of mathematical calculations with rich set of
methods as Min, Abs, Max, Sqrt and so on".
Step 1: Create
a new WebForm project
Step 2: The
complete code of WebForm1.aspx looks like this

Step 3: The
complete code of WebForm1.aspx.cs looks like this
using
System;
using
System.Collections.Generic;
using
System.Linq;
using
System.Web;
using
System.Web.UI;
using
System.Web.UI.WebControls;
namespace
MathClassApp
{
public partial
class WebForm1 : System.Web.UI.Page
{
protected void
Page_Load(object sender,
EventArgs e)
{
TextBox2.Focus();
}
protected void
Button1_Click(object sender,
EventArgs e)
{
if (string.IsNullOrEmpty(TextBox2.Text))
{
Label5.Text =
"Please Enter Some Values";
Label5.ForeColor = System.Drawing.Color.Red;
}
else
{
Label5.Text =
"SquareRoot Result is: " +
Math.Sqrt(double.Parse(TextBox2.Text));
Label5.ForeColor = System.Drawing.Color.Green;
TextBox1.Text
= string.Empty;
TextBox2.Text
= string.Empty;
}
}
protected void
Button2_Click(object sender,
EventArgs e)
{
if (string.IsNullOrEmpty(TextBox1.Text)
|| string.IsNullOrEmpty(TextBox2.Text))
{
Label5.Text =
"Please Enter Some Values";
Label5.ForeColor = System.Drawing.Color.Red;
}
else
{
Label5.Text =
"Maximum Value is: " +
Math.Max(double.Parse(TextBox2.Text),
double.Parse(TextBox1.Text));
Label5.ForeColor = System.Drawing.Color.Green;
TextBox1.Text
= string.Empty;
TextBox2.Text
= string.Empty;
}
}
protected void
Button3_Click(object sender,
EventArgs e)
{
if (string.IsNullOrEmpty(TextBox1.Text)
|| string.IsNullOrEmpty(TextBox2.Text))
{
Label5.Text =
"Please Enter Some Values";
Label5.ForeColor = System.Drawing.Color.Red;
}
else
{
Label5.Text =
"Minimum Value is: " +
Math.Min(double.Parse(TextBox2.Text),
double.Parse(TextBox1.Text));
Label5.ForeColor = System.Drawing.Color.Green;
TextBox1.Text
= string.Empty;
TextBox2.Text
= string.Empty;
}
}
}
}
Step 4: The
output of the application looks like this
Step 5: The
minimum result output of the application looks like this
