读取变量-从位于项目其他文件夹中的类

Question

我有以下课程：

Class2 ：

namespace readingvaraibles.Folder1
{
    class Class2
    {
        public int variable_1 = 1;
        public int variable_2 = 2;


    }
}

Class3 也嵌套了 Class4 ：

namespace readingvaraibles.Folder2
{
    class Class3
    {
        public int variable_3 = 3;
        public int variable_4 = 4;

        class Class4
        {
            public int variable_5 = 5;
            public int variable_6 = 6;
        }
    }
}

我该怎么做才能从下一个类的Class2，Class3，Class4中读取变量？

Class1

namespace readingvaraibles
{
    public class Class1
    {
    }
}

Answer 1

      namespace readingvaraibles
     {
         public class Class1
        {
           public Class2 Class2 {get;set}
           public Class3 Class3 {get;set;
        }
     }

     var class1 = new Class1();
     var class2 = new class1.Class2();
     var variable1 = class2.variable_1;
     var variable2 = class2.variable_2;

     var class3 = new class1.Class3();
     var variable3 = class3.variable3;

等...
