How to Generate Random Numbers in C# and ASP.NET

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 1: Create a new Empty Website named "Website1" using Visual Studio.

 

 

And add the Web form named "Deafult.aspx" into it.

 

 

Step 2: Add a button to the "Deafult.aspx" page with the Text "Generate Random Number" and a click event.

 

 

Step 3: Write the code on button click event.

 

Create an object of the "Random" class. 

Random r = new Random();

To get the next value of the random object and save the output in an int variable named "num". 

int num=r.Next();
Print the "num" variable.
Response.Write(num.ToString());

 

 

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.

 

Note: You can also set the range of random numbers. In my future article you can see that.
