清除为可空布尔值编写代码的方法

Question

是否有更简洁的方法来编写此代码。我觉得可能有，但我不知道如何。

    if (loadedFormData.Education.AwardedADegree==true)
    {
        this.radiobuttonNoAwarded.Checked = false;
        this.radiobuttonYesAwarded.Checked = true;
    }
    if (loadedFormData.Education.AwardedADegree == false)
    {
        this.radiobuttonNoAwarded.Checked = true;
        this.radiobuttonYesAwarded.Checked = false;
    }
    else // AwardedADegree is null
    {
        this.radiobuttonNoAwarded.Checked = false;
        this.radiobuttonYesAwarded.Checked = false;

    }

Answer 1

提出问题“我的radiobutton何时应该被检查”，而不是“当我的数据为真/假/空时会发生什么”。

this.radiobuttonNoAwarded.Checked = loadedFormData.Education.AwardedADegree == false;
this.radiobuttonYesAwarded.Checked =  loadedFormData.Education.AwardedADegree == true;

Answer 2

我假设bool?允许该值为空。

this.radiobuttonNoAwarded.Checked = AwardedADegree.HasValue && AwardedADegree.Value;
this.radiobuttonYesAwarded.Checked = AwardedADegree.HasValue && !AwardedADegree.Value;

Answer 3

试试这个：

 this.radiobuttonNoAwarded.Checked = (!loadedFormData.Education.AwardedADegree) ?? false;
 this.radiobuttonYesAwarded.Checked = loadedFormData.Education.AwardedADegree ?? false;

Answer 4

this.radiobuttonNoAwarded.Checked = (loadedFormData.Education.AwardedADegree ?? false);
this.radiobuttonYesAwarded.Checked = !(loadedFormData.Education.AwardedADegree ?? true);
