c# - 为可为空的布尔值编写代码的简洁方法

Question

有没有更简洁的方法来编写这段代码。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

问“什么时候应该radiobutton检查我”的问题，而不是“当我的数据为真/假/空时应该发生什么”。

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

尝试这个 ：

 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);
