ASP.NET while loop

The "while" loop is a fundamental construct in ASP.NET (as well as in many other programming languages) that allows for repetitive execution of a block of code as long as a specified condition is true. It provides flexibility in controlling the iteration process based on a condition that is checked before each iteration.

Syntax:
while (condition) { // Code block to be repeated }

The condition is a Boolean expression that evaluates to either true or false. If the condition is true, the code block is executed. If the condition is false, the loop terminates.

Here is an example of an ASP.NET while loop:

int i = 0; while (i < 10) { // Code block to be repeated Console.WriteLine("i = {0}", i); i++; }

This code will print the numbers from 0 to 9. The condition in this loop is i < 10, which means that the loop will repeat as long as the value of i is less than 10. When the value of i reaches 10, the condition will become false and the loop will terminate.

Here is another example of an ASP.NET while loop:

string input = ""; while (input != "exit") { // Code block to be repeated Console.WriteLine("Enter 'exit' to quit:"); input = Console.ReadLine(); }

This code will prompt the user to enter a string. The loop will repeat as long as the user does not enter the string "exit". When the user enters "exit", the condition will become false and the loop will terminate.

Conclusion

The "while" loop is commonly used in ASP.NET when the number of iterations is not predetermined, and the loop continues until a specific condition is no longer true. It provides a flexible and versatile way to repeatedly execute a block of code based on a condition.
