Keywords (Visual Basic)

The following tables list all Visual Basic language keywords.

The following keywords are reserved, which means that you cannot use them as names for programming elements such as variables or procedures. You can bypass this restriction by enclosing the name in brackets ([ ]). For more information, see "Escaped Names" in Declared Element Names (Visual Basic).

Note Note

We do not recommend that you use escaped names, because it can make your code hard to read, and it can lead to subtle errors that can be difficult to find.

Note Note

EndIf , GoSub, Variant, and Wend are retained as reserved keywords, although they are no longer used in Visual Basic. The meaning of the Let keyword has changed. Let is now used in LINQ queries. For more information, see Let Clause (Visual Basic).

The following keywords are not reserved, which means you can use them as names for your programming elements. However, doing this is not recommended, because it can make your code hard to read and can lead to subtle errors that can be difficult to find.
