在C中调用覆盖构造函数和基址＃

Question

如何解决无错误代码的错误？

public Comparison2(decimal number1, decimal number2) : base() 
    { 
     this.Number1 = number1; 
     this.Number2 = number2; 
    } 

    public Comparison2(decimal number1, decimal number2, int problemNumber, int subject, int seconds) 
     : this(number1, number2), base(problemNumber, subject, seconds) { } 

Answer 1

我认为你唯一的选择是要做到这一点：

public Comparison2(decimal number1, decimal number2) : base() 
{ 
    this.SetNumbers(number1, number2); 
} 

public Comparison2(decimal number1, decimal number2, int problemNumber, 
     int subject, int seconds) 
    : base(problemNumber, subject, seconds) 
{ 
    this.SetNumbers(number1, number2); 
} 

private void SetNumbers(decimal number1, decimal number2) 
{ 
    this.Number1 = number1; 
    this.Number2 = number2; 
} 

Answer 2

有时，多次写入相同的代码是最好的选择，尤其是当它很简单时。

但是，如果你真的想避免重复自己，或者如果你的实际代码更复杂，你可以创建一个方法来包含代码。这种方法的一个缺点是您不能在构造函数外设置readonly字段。
