如果Object是String，测试的语法是什么？ [英] What is syntax to test if Object is a String?

问题描述

我想知道检查Object是否为字符串的语法。


如果是数字测试，我可能会使用IsNumeric。

但是没有功能：IsString（有吗？）

I would like to know the syntax to check that an Object is a String.

If it was a number test I might use IsNumeric.
But there is no function: IsString (is there?)

Dim o As Object = 2
Dim p As Object =" Hello"

Dim q As Object = Me

MsgBox（TypeOf o Is String）

MsgBox（TypeOf p是字符串）

MsgBox（TypeOf q是字符串）
