在C中調用覆蓋構造函數和基址＃

Question

如何解決無錯誤代碼的錯誤？

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

我認爲你唯一的選擇是要做到這一點：

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

有時，多次寫入相同的代碼是最好的選擇，尤其是當它很簡單時。

但是，如果你真的想避免重複自己，或者如果你的實際代碼更復雜，你可以創建一個方法來包含代碼。這種方法的一個缺點是您不能在構造函數外設置readonly字段。
