这是我想写的结构:

  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; }
        }

这会导致以下编译错误:

在分配所有字段之前,不能使用"this"对象 …

假设我们有这两个结构......

public struct Example
{
    public int Number { get; set; }

    public Example(int Number)
    {
        Number = number;
    }
}

和：

public struct Example
{
    public int Number { get; set; }

    public Example(int number) : this()
    {
        Number = number;
    }
}

你可以看到有一个结构体，**this()**最后有一个构造函数，另一个没有。

两者有什么区别？
