我正在尝试创建包含客户联系信息和地址信息的类。

我目前正在尝试重载方法，以期压缩我的代码并使其更易于阅读，同时执行与各种方法相同的操作。另外，我正在使用 NUnit，因为这些是我正在创建的集成测试，所以这就是随机生成器的来源。这是我到目前为止所拥有的：

  public static Address BuildAddress()
    {
        var gen = new RandomGenerator();
        return BuildAddress(gen.Phrase(10));
    }

    //build a billing address
    public static AddressInfo BuildAddress(string name)
    {
        return BuildAddress(name, "USA");
    }

    public static Address BuildAddress(string name, string country)
    {
        var gen = new RandomGenerator();

        var address = Builder<AddressInfo>.CreateNew()
            .With(x => x.Name = name)
            .And((x => x.Address1 = gen.Int() + " " + gen.Phrase(10) + " Street"))
            .And(x => x.City = gen.Phrase(15))
            .And(x => x.StateOrProvince = gen.Phrase(2))
            .And(x => x.Country = country)
            .And(x => x.PostalCode = "32561").
            Build();

        return address;

我做了这个，但我也在想我需要为邮寄地址添加另一个代码块。如果有更短的方法可以做到这一点，请告诉我。

谢谢！

如果我理解正确，您想缩短上面的代码，即您拥有的方法重载链......您可以使用默认属性，即：

public static Address BuildAddress(string name, int phrase = 10, string country = "USA")
{
        var gen = new RandomGenerator();

        var address = Builder<AddressInfo>.CreateNew()
            .With(x => x.Name = name)
            .And((x => x.Address1 = gen.Int() + " " + gen.Phrase(10) + " Street"))
            .And(x => x.City = gen.Phrase(15))
            .And(x => x.StateOrProvince = gen.Phrase(2))
            .And(x => x.Country = country)
            .And(x => x.PostalCode = "32561").
            Build();

        return address;
}

然后你可以这样称呼它..

ClassName.BuilderAddress("my name");

或者..

ClassName.BuilderAddress("my name", 5);

或者..

ClassName.BuilderAddress("my name", 7, "Ireland");

对您的评论的建议答案如下：（对此不是 100% 确定）

public static T BuildAddress(string name, int phrase = 10, string country = "USA")
{
        var gen = new RandomGenerator();

        var address = Builder<T>.CreateNew()
            .With(x => x.Name = name)
            .And((x => x.Address1 = gen.Int() + " " + gen.Phrase(10) + " Street"))
            .And(x => x.City = gen.Phrase(15))
            .And(x => x.StateOrProvince = gen.Phrase(2))
            .And(x => x.Country = country)
            .And(x => x.PostalCode = "32561").
            Build();

        return address;
}

您可能需要考虑可选参数和命名参数。
