c# - 结构构造函数: “fields must be fully assigned before control is returned to the caller.”

这是我尝试编写的结构:

  public struct AttackTraits
        {
            public AttackTraits(double probability, int damage, float distance)
            {
                Probability = probability;
                Distance = distance;
                Damage = damage;
            }

            private double probability;
            public double Probability
            {
                get
                {
                    return probability;
                }
                set
                {
                    if (value > 1 || value < 0)
                    {
                        throw new ArgumentOutOfRangeException("Probability values must be in the range [0, 1]");
                    }
                    probability = value;
                }
            }

            public int Damage { get; set; }

            public float Distance { get; set; }
        }

这将导致以下编译错误:



我究竟做错了什么？

最佳答案

您是通过probability属性设置Probability字段的，但是编译器并不知道该属性会设置该字段...因此您需要显式初始化概率字段本身

public AttackTraits(double probability, int damage, float distance)
{
    this.probability = 0;
    Distance = distance;
    Damage = damage;
}
