Question

我得到了一个名为classList的类列表。此列表中的每个类都有一个带有字符串参数的构造函数，该参数包含有关该类的一些信息。我想迭代classList，然后将所有构造函数参数添加到stringarray。我怎么能这样做？

public Main()
    {
        classList = new List<class>();
        class1 = new class1("class1 information");
        class2 = new class2("class2 information");
        classList.Add(class1);
        classList.Add(class2);
    }

public void getConstructorParametersToList()
    {
        string[] myArrayList = null;
        for(int i = 0; i < classList.Count; i++)
        {
            //Add the parameters from the constructors to a string array
            myArrayList[i] = parameterfromconstructor
        }
    }

public void doSomething()
    {
        foreach (string s in myArrayList)
        {
            Console.WriteLine(s);
        }
    }
//Output:
//Class1 information
//Class2 information

您可以将该构造函数参数存储在类字段或属性中，然后再访问它。

public interface IParameterizedClass
{
   string ClassParameter {get}
}

public class class1 : IParameterizedClass
{
   public string ClassParameter {get; private set;}
   public class1(string someParameter)
   {
     // do some work

     ClassParameter = someParameter;
   }
}  

public class class2 : IParameterizedClass
{
   public string ClassParameter {get; private set;}
   public class2(string someParameter)
   {
     // do some work

     ClassParameter = someParameter;
   }
}

public void getConstructorParametersToList()
{
    string[] myArrayList = null;
    for(int i = 0; i < classList.Count; i++)
    {
        //Add the parameters from the constructors to a string array
        myArrayList[i] = (classList[i] as IParameterizedClass).ClassParameter;
    }
}

如何将constructors参数添加到列表中？
