我有以下的code：

var bool:String = "true";

没有的，如果块或switch语句，这可怎么转换成一个Boolean对象？

Without an if block or switch statement, how can this be converted into a Boolean object?

推荐答案

您可以使用：

var boolString:String = "true";
var boolValue:Boolean = boolString == "true"; // true
var boolString2:String = "false";
var boolValue2:Boolean = boolString2 == "true"; // false

修改

下面留言建议使用

var boolValue:Boolean = (boolString == "true") ? true : false;

这仅仅是复杂的code无缘无故作为评价发生在部分：

This is just complicating the code for no reason as the evaluation happens in the part:

(boolString == "true")

使用三元操作等效于：

Using the ternary operator is equivalent to:

var tempValue:Boolean = boolString == "true"; // returns true: this is what I suggested
var boolValue:Boolean = tempValue ? true : false; // this is redundant
