AS3，从字符串到数据类型x的动态转换

Question

是否有动态转换的方法？

这是默认的方式转换成字符串：

VAR toVal：* = INT（ “5”）;
var toVal：* = Boolean（“true”）;

但我wan't做到这一点：

变种类型：字符串= “INT”;
var toVal：* = type（“5”）; // < < < < <我怎么能做到这一点

尝试之一：

var type:Class = int; 
// or 
var type:Class = flash.utils.getDefinitionByName("int") as Class; 

var toVal:* = type("5"); 

示例程序：

var test:* = "5"; 

var type:Class = flash.utils.getDefinitionByName("int") as Class; 

var toVal:* = type("5"); 

if(test is String) { 
    trace("Test is a string"); // traces 
} 

if(test is int) { 
    trace("Test is an int"); // ignored 
} 

if(toVal is String) { 
    trace("toVal is a string"); // ignored 
} 

if(toVal is int) { 
    trace("toVal is an int"); // traces 
}
