In addition to the basic For loop syntax, VB also provides the For Each loop, which is used to iterate over a collection of objects or elements such as arrays, lists, or controls. The For Each loop eliminates the needfor maintaining a loop counter variable and simplifies the process of it...
From this example, it is very clear that the “For” loop has helped us avoid typing/copying 51 statements and printing the numbers in continuous order. Justone statementwithin the loop used wisely following the syntax has saved us a lot of time. How to Break the Loop: The “Exit For”...
Do While counter < iNumber 'The do loop will exit when the value of counter becomes 9 counter = counter + 1 Loop MsgBox counter For…Next Statement A For…Next loop instructs UFT One to iterate one or more statements a specified number of times. The following is the syntax of For..Ne...

vb Dim count As Integer = 1 Do While count <= 5 Console.WriteLine("计数: " & count) count += 1 Loop 输出: 计数: 1 计数: 2 计数: 3 计数: 4 计数: 5 3. Do Until 循环 Do Until 循环用于在条件为 False 时重复执行代码。循环会在条件变为 True 时停止。

vb.net跳出循环函数 vb.net for循环语句 循环语句 VB.Net中的循环语句分为:Do While Loop、For Next、For Each三种。 Do While Loop Do While Loop有三种形式,这系列的循环是用于预先不知道循环的上限时使用的。在使用Do While Loop语句时要注意,因为它们是不确定循环次数,所以要小心不要造成死循环。
//首先奇数不能被2整除，这就是突破口，我利用C#的语法写的，你可以作为参考，原理是一样的 int sum=0;int i=1; //初始值是1 int totol=99; //最大值是99 for(i=1;i<=99;i++) //遍历1到99 { if(i%2!=0) //不能被2整除，则是奇数 {sum+=i;} i++;} return ...
通过巧妙地利用Do...Loop，开发者可以实现几乎所有的循环需求。总之，选择合适的循环结构取决于具体的应用场景。For...Next适用于已知循环次数的情况，而Do...Loop则更适合需要动态控制循环次数的场景。通过灵活运用这两种循环结构，可以编写出更加高效和灵活的VB程序。
在VB中,常用的循环语句如下分析:- **A. For ... Next**:正确的循环语句,用于已知循环次数的情况。例如,迭代数组或重复执行固定次数的操作。- **B. Do ... Loop**:正确的循环语句,适用于条件循环。常见的变体包括`Do While ... Loop`、`Do Until ... Loop`,根据条件控制循环执行。- **C. Selec...
