有关类型转换的帮助 [英] Help on Type Casting

问题描述

为什么这不起作用?

Why isn''t this working ?

Dim x As Integer = 90
 Dim temp As Object
 Dim typ As Type = Type.GetType("System.String")
 temp = CType(x, Typ)

它在Ctype函数的第二个参数中显示错误. :doh:

It shows error in 2nd argument of Ctype function. :doh:

推荐答案

CType出现错误，因为x(整数)和typ( Type !!! )之间没有有效的转换.您可能想使用CType(x，String)甚至CType(x，Object).
无论如何，为什么不使用x.ToString()?

干杯

CType gives the error because there is no valid conversion between x (Integer) and typ(Type!!!). You would want to use CType(x, String) or even CType(x, Object).
Anyhow why not use x.ToString()?
