Comment refactoriser ces constructeurs de classes surchargés? (C#)

Question

Je ne veux pas répliquer le code à travers les constructeurs surchargés comme ci-dessous. Comment puis-je le refactoriser?

/// <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; 
    } 
} 

Answer 1

Étant donné que vous ne pouvez pas nourrir le constructeur de base une graine 0 quand aucune graine n'est fournie, ce serait ce que vous voulez:

/// <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; 
    } 
}

Que pensez-vous de cela?

public class NormalDeviate : UniformDeviate 
{ 
    double mean; 
    double standardDeviation; 
    double storedValue; 

    /// <summary> 
    /// Initializes a new instance of the <see cref="NormalDeviate"/> class. 
    /// </summary> 
    /// <param name="mean">The mean.</param> 
    /// <param name="standardDeviation">The standard deviation. The distance from the mean where 78.2% of the samples lie.</param> 
    /// <param name="seed">The seed.</param> 
    public NormalDeviate(double mean, double standardDeviation, ulong seed) : base(seed) 
    { 
     this.mean = mean; 
     this.standardDeviation = standardDeviation; 
     this.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. The distance from the mean where 78.2% of the samples lie.</param> 
    public NormalDeviate(double mean, double standardDeviation) 
     : this(mean, standardDeviation, 0) 
    { 

    } 
} 

EDIT: Code fixe

Answer 3

public ClassName(double arg1, double arg2, double arg3) : base(arg3) 
{ 
    _member1 = arg1; 
    _member2 = arg2; 
} 
public ClassName(double arg1, double arg2) : this(arg1,arg2,0) { } 
public ClassName(double arg1) : this(arg1,0,0) { }
