確認する条件が多数ある場合、またはユーザーの選択に基づいて何らかの操作を実行する場合は、If ElseIfステートメントを使用できます。しかし、複数の条件になると面倒です。その場合、ExcelVBAの最適なソリューションはSelectCase * methodです。

VBAのSelectCaseステートメントとは何ですか?

VBAのSelectCaseステートメントは、チェックする条件が複数ある場合に役立ちます。それらは他のプログラミング言語のswitchステートメントのようなものです。指定された変数をチェックし、一致したケースを実行します。

ExcelVBAでのSelectCaseの構文

Select Case variable

case Condition1

result1

case Condition2

Condition2

ケースConditionN

resultN

[その他の場合

resultElse]

Select Case:Here Select Case* is a keyword to start the case check.

Variable: Variable is any variable that you want to check.

Case: from the next line, we start checking the conditions with variables.

You can have as many conditions as you want. We can check any condition with the keyword case. The condition can be a logical statement or a straight value of the Selected Variable. It will always result in true-false value. These all are valid statements:

ケース領域を選択

‘直線値を使用

ケース「中央」

Range( “D1″)。Value = region

‘isステートメントを使用する

ケースは= “中央”

Range( “D1″)。Value = region

選択の終了

With is you can put arithmetic logical operators to check if the Case is equal to(=), greater than(>), less than(<), etc.

You can use the comma (",") to do one operation on multiple conditions (like or operator).

ケースは= “West”、 “North”、 “South”

Range( “D1″)。Value = region

You can also use To operator to check among large ranges.

ケース1から40

グレード= “F”

ケース41から60

Grade = “C”

ケース61から80

Grade = “B”

ケース81から100

Grade = “A”

The Case Else statement is optional. You can use it to do something by default if none of the case match. Like showing a message that the choice is invalid or something.

その他の場合

MsgBox「無効なオプション」

Now that we know about the basics of the Select Case, let's have an example.

===  Example: Create A Grading Function UsingVBA Select Case We need to create a function that checks the supplied value and returns the grades according to below rules:

*  If >41, Grade="F"

*  If between 41 and 60, Grade="C"

*  If between 61 and 80, Grade="B"

*  If between 81 and 100, Grade="A"

*  else #VALUE! error.

We will use the Select Case as a Switch statement of VBA here. The code for the custom function will be:

関数GRADES(num As Double)

ケース番号を選択

ケースは<41です

GRADES = “F”

ケース41から60

GRADES = “C”

ケース61から80

GRADES = “B”

ケース81から100

GRADES = “A”

その他の場合

GRADES = “#VALUE!”

選択の終了

終了機能

Now if you use this function on the sheet, it will return the grades easily.

So yeah guys, this is how the Select Case (switch) statement is used in Excel VBA to check multiple conditions. Instead of multiple If Else If statement we use the Select Case statement to switch results.
