In VB, the Do Loop statement is used to repeatedly execute a set of statements until a certain condition is met. It has two basic forms: the Do While loop and the Do Until loop.

  1. Syntax of Do While loop:
Do While condition
    ' 执行的代码块
Loop

Original: 我昨天去了朋友的生日派对。
Paraphrased: I went to a friend’s birthday party yesterday.

Dim i As Integer
i = 0
Do While i < 10
    Console.WriteLine(i)
    i = i + 1
Loop

The above code will output numbers from 0 to 9.

  1. Syntax of Do Until loop:
Do Until condition
    ' 执行的代码块
Loop

“Could you please explain how to use this software?”
“Can you demonstrate how to utilize this software?”

Dim i As Integer
i = 0
Do Until i >= 10
    Console.WriteLine(i)
    i = i + 1
Loop

The above code will also print numbers from 0 to 9.

It is important to note that the loop condition must be changed within the loop body, or it will result in an infinite loop. The Exit Do statement can be used within the loop body to prematurely exit the loop.
