在某些情况下,您需要多次执行一个代码块。通常,语句是按顺序执行的:函数的第一个语句首先执行,然后第二个执行,依此类推。
编程语言提供了各种控制结构,允许更复杂的执行路径。
循环语句使我们可以多次执行一个语句或一组语句。以下是VBA中循环语句的一般形式。
VBA提供以下类型的循环来处理循环需求。单击以下链接以查看其详细信息。
Sr.No. | Loop Type & Description |
---|---|
1 |
for loop
Executes a sequence of statements multiple times and abbreviates the code that manages the loop variable. |
2 |
for ..each loop
This is executed if there is at least one element in the group and reiterated for each element in a group. |
3 |
while..wend loop
This tests the condition before executing the loop body. |
4 |
do..while loops
The do..While statements will be executed as long as the condition is True.(i.e.,) The Loop should be repeated till the condition is False. |
5 |
do..until loops
The do..Until statements will be executed as long as the condition is False.(i.e.,) The Loop should be repeated till the condition is True. |
循环控制语句从其正常顺序更改执行。当执行离开作用域时,将不执行循环中的所有其余语句。
VBA支持以下控制语句。单击以下链接以查看其详细信息。
S.No. | Control Statement & Description |
---|---|
1 |
Exit For statement
Terminates the For loop statement and transfers the execution to the statement immediately following the loop |
2 |
Exit Do statement
Terminates the Do While statement and transfers the execution to the statement immediately following the loop |
