c# - 如何重构这些重载的类构造函数？ (C#)

Question

我不想像下面这样跨重载构造函数复制代码。我该如何重构它？

/// <summary>
/// Represents a pseudo-random number generator, a device that
/// produces a sequence of numbers that are normally distributed.
/// </summary>
public class NormalDeviate : UniformDeviate
{
    double mean;
    double standardDeviation;
    double storedValue = 0d;

    /// <summary>
    /// Initializes a new instance of the <see cref="NormalDeviate"/> class.
    /// </summary>
    /// <param name="mean">The mean.</param>
    /// <param name="standardDeviation">The standard deviation.</param>
    /// <param name="seed">The seed.</param>
    public NormalDeviate(double mean, double standardDeviation, ulong seed)
        : base(seed)
    {
        this.mean = mean;
        this.standardDeviation = standardDeviation;
    }

    /// <summary>
    /// Initializes a new instance of the <see cref="NormalDeviate"/> class.
    /// </summary>
    /// <param name="mean">The mean.</param>
    /// <param name="standardDeviation">The standard deviation.</param>
    public NormalDeviate(double mean, double standardDeviation)
        : base()
    {
        this.mean = mean;
        this.standardDeviation = standardDeviation;
    }
}

鉴于您无法在未提供种子时向基本构造函数提供 0 种子，这就是您想要的:

/// <summary>
/// Represents a pseudo-random number generator, a device that
/// produces a sequence of numbers that are normally distributed.
/// </summary>
public class NormalDeviate : UniformDeviate
{
    double mean;
    double standardDeviation;
    double storedValue = 0d;

    /// <summary>
    /// Initializes a new instance of the <see cref="NormalDeviate"/> class.
    /// </summary>
    /// <param name="mean">The mean.</param>
    /// <param name="standardDeviation">The standard deviation.</param>
    /// <param name="seed">The seed.</param>
    public NormalDeviate(double mean, double standardDeviation, ulong seed)
        : base(seed)
    {
        CommonInitialization(mean, standardDeviation);
    }

    /// <summary>
    /// Initializes a new instance of the <see cref="NormalDeviate"/> class.
    /// </summary>
    /// <param name="mean">The mean.</param>
    /// <param name="standardDeviation">The standard deviation.</param>
    public NormalDeviate(double mean, double standardDeviation)
        : base()
    {
        CommonInitialization(mean, standardDeviation);
    }

    private void CommonInitialization(double mean, double standardDeviation)
    {
        this.mean = mean;
        this.standardDeviation = standardDeviation;
    }
}
