使用循环和"干净"代码在多个级别添加多个子级

Question

我有一个C#类,可以包含多个级别的多个子级.

手动添加子项看起来像这样:

CustomClass MyClass = new CustomClass(“something”, new List<CustomClass>());
//Level 1
MyClass.Children.Add(“something”, new List<CustomClass>());
//Level 2
MyClass.Children[0].Children.Add(“something”, new List<CustomClass>());
//Level 3
MyClass.Children[0].Children[0].Children.Add(“something”, new List<CustomClass>());

我怎么用干净的循环呢？这样做,感觉"不对":

for (var i = 0; i < 50; i++) {
   //Level 1
   if (i == 0)
        MyClass.Children.Add(“something”, new List<CustomClass>());
   //Level 2
   if (i == 1)
        MyClass.Children[0].Children.Add(“something”, new List<CustomClass>());
   //Level 3
   if (i == 2)
        MyClass.Children[0].Children[0].Children.Add(“something”, new List<CustomClass>());

    // and so on up to 50 levels in this case ...
}

重要更新:在每个级别,我需要检查值是否已经存在,如果不存在,我添加它.

谢谢你的聆听!

我是初学者所以请温柔.

你可以递归地做:

void FillChildren(CustomClass lastChild, int levels)
{
    if(levels > 0)
    {
        CustomClass child = new CustomClass(“something”, new List<CustomClass>());
        FillChildren(child, levels-1);
        lastChild.Children.Add(“something”, child);
    }
}

您可以这样称呼:

CustomClass MyClass = new CustomClass(“something”, new List<CustomClass>());

FillChildren(MyClass, 50);
