Vb which case

However, we can use the ToLower and the ToUpper functions to handle the issue of a case with this statement. Step 3 Click the Start button on the top bar to run the code. You should get the following output:. Step 4 Type the name Guru99 G is uppercase and press the enter key on your keyboard.

Code line 5: The value of the variable name will be used for performing comparisons with the various Case statements to find a match. The ToLower function will ensure that any name the user types is first converted into lowercase before the evaluation of Case statements.

This means that if the user types Guru99, it will be immediately converted to guru99, then the evaluation of the Case statements is done. If the user types John, it will be immediately be converted to john before the evaluation of the Case statements is done. Skip to content. The Case statements can get a little more complex. For example, you may want to distinguish a case where the variable is larger or smaller than a value. To implement this logic, use the Is keyword, as in the following code segment that distinguishes between the first and second half of the month:.

Skip to main content Skip to primary sidebar Skip to secondary sidebar. Case Else statementblockN End Select. Select Case Now. Tuesday, DayOfWeek. On values, Select Case is implemented with the switch opcode in the intermediate language. This is the same implementation as the switch keyword from the C language. Note: With this opcode, Select Case is faster on certain programs and data than an If-statement. However: Performance of Select Case is highly dependent on both the cases, and the data, in your program.

And: If we have 1, cases, but one is most common, testing for the common one with an If-statement is fastest. If the frequency of cases is equally distributed, and the values are close together, a Select Case is better. The performance difference in most situations is small. A summary. The Select Case statement optimizes selection from several constant cases. This special syntax form can be used to test a variable against several constant values. A nested Select Case is shown. Select Case. In branches, in selection statements, programs change course.

Select Case rapidly matches values. In it, we specify a set of constants Integers, Chars, Strings. Based on:. NET 4. Parse Console. WriteLine "You typed one" Case 2 Console. WriteLine "You typed two" Case 5 Console. If the information matches any labels, the code for that case label will execute; otherwise the Case Else will execute.

This is not in our case label, as it actually appears all upper-case, so we can solve this issue by using the ToLower method.
