Question

在尝试调用基础构造函数时，它会抛出错误，例如“对象不包含带有一个参数的构造函数”

    public string FirstName { get;private set; }
    public string LastName { get;private set; }

    public Employee(string firstName)
    {
        FirstName = firstName;
    }

    public Employee(string firstName,string lastName):base(firstName)//error
    {
        LastName = lastName;
    }

    public string SayHello()
    {
        return FirstName + " " + LastName;
    }

感谢

您可能想要调用 current clas 的构造函数，而不是基类构造函数：

public Employee(string firstName, string lastName): this(firstName) // this, not base
{
    LastName = lastName;
}

如何将基础构造函数数据用于同一个类中的另一个构造函数？
