c# - 如何使用字符串从多个类中获取变量的值

Question

我正在尝试制作可以加载各种数据的表。数据格式是类，类中有各种变量，格式是字符串、浮点数和双精度。

我的数据格式如下。所有数据将保存到 TotalData 类

public class TotalData
{
    public List<A> aList;
    public List<B> bList;
}

public class A
{
    public int classA_intA;
    public int classA_intB;
    public float classA_floatA;
    public float classA_floatB;
}

public class B
{
    public int classB_intA;
    public int classB_intB;
    public double classB_doubleA;
    public double classB_doubleB;
    public double classB_doubleC;
    public double classB_doubleD;
    public double classB_doubleE;
    public double classB_doubleF;
}

设置完成后，我想按类名和变量名搜索特定数据。

例如，如果我想获取classB_doubleB，那么我需要bList的名称作为字符串从 TotalData 和 classB_doubleB 的名称中搜索，这样我就可以获得classB_doubleB的值

public object GetValueFromTotalData(string getDataFromClass, 
                                    string nameOfVariable, 
                                    TotalData data, 
                                    int indexOfList) 
{
    //The string getDataFromClass selects a list to find the variable.

    //The string nameOfVariable selects variable which in selected class

    //indexofList is for choose index of aList or bList
    return value;
}

我希望有人能解决我的问题。谢谢你。:)

PS。下面的脚本是我实际工作的数据格式。

这将是解决您的问题的最佳方式。使用 if 语句来控制应用程序的流程。

public object GetValueFromTotalData(string getDataFromClass, 
                                    string nameOfVariable, 
                                    TotalData data, 
                                    int indexOfList) 
{
    //check the value string getDataFromClass and initialize the correct class to search from
    if(getDataFromClass == "aList"){
        //initialize and access aList
    } else {
        //initialize and access bList
    }

    //use the same if statements as above to access the correct class and initialize it

    //again use an if statement to select index of item from the list set up above
    return value;
}

但是，您可以使用可用于初始化正确类的接口。这两个具体类都将从该接口继承，您将在方法中使用正确的类来初始化接口。
