如何显示是/否，而不是True / False for bool？在c＃ [英] How to display Yes/No instead of True/False for bool? in c#

问题描述

我收到错误无法将类型'string'隐式转换为'bool'如何返回是或否而不是true / false？

I get the error "Cannot implicitly convert type 'string' to 'bool'. How do I return 'Yes' or 'No' instead of true/false?

public bool? BuyerSampleSent
{
    get { bool result;
          Boolean.TryParse(this.repository.BuyerSampleSent.ToString(), out result);
        return result ? "Yes" : "No";
    }
    set { this.repository.BuyerSampleSent = value; }
}

推荐答案

如果返回类型为<在这种情况下，code> bool （或 bool？）返回一个 bool ：

You can't return a string if the return type is bool (or bool? in this case). You return a bool:

return result;

请注意，您要求...

Notice, however, that you ask...

如何显示是/否...

此代码不显示任何东西，这是一个属性一个对象，而不是UI组件。在UI中，您可以移动ay你喜欢使用这个属性作为一个标志：

This code isn't displaying anything. This is a property on an object, not a UI component. In the UI you can display whatever you like using this property as a flag:

someObject.BuyerSampleSent ? "Yes" : "No"

相反，如果要在对象本身上显示友好的信息（也许这是一个视图模型？）然后您可以添加该消息的属性：

Conversely, if you want a display-friendly message on the object itself (perhaps it's a view model?) then you can add a property for that message:

public string BuyerSampleSentMessage
{
    get { return this.BuyerSampleSent ? "Yes" : "No"; }
}
