System :: Boolean变量上的三元运算符 [英] Ternary operator on System::Boolean variable

问题描述

如何在System :: Boolean中使用三元运算符？此示例代码始终返回true：

How to use ternary operator with System::Boolean? This sample code always returns true:

bool Test(Boolean^ value)
{
  return value ? true : false;
}

推荐答案

回答我自己的过早问题，这段代码有效：

Answering my own premature question, this code works:

bool Test(Boolean^ value)
{
  return (bool)value ? true : false;
}

编辑：更好（并且遵循汉斯和马特的建议），此代码有效更好：

better yet (and following Hans' and Matt's advice) this code works better:

bool Test(Boolean value)
{
  return value ? true : false;
}

或者，因为布尔值和布尔值是可转换的，所以这也是很好的代码，这取决于自动转换发生在其他地方。除显示三元运算符外，示例几乎没有意义：

Or, because Boolean and bool are convertible this is also good code, which relies on automatic conversion that happens elsewhere. Example has very little sense except for showing the ternary operator:

bool Test(bool value)
{
  return value ? true : false;
}
