Sometimes developers need to generate random numbers in a Web page or website. This article demonstrates how to create a simple Web page using ASP.NET and generates and displays a random number using the Random class available in C# and .NET.
For generating a random number, you can use the Random class in C# that resides in the "System" Namespace.

Step 3: Write the code on button click event.
Create an object of the "Random" class.
  1. Random r = new Random();
To get the next value of the random object and save the output in an int variable named "num".
  1. int num=r.Next();
  2. Print the "num" variable.
  3. Response.Write(num.ToString());
num
Step 4: After running the page.

After clicking the button, first I got "369593053" as the random number.
And the second time, I got "820031117" as the random number.

The name of a character array is actually a pointer to the first element of the array.
