c# - 使用循环和 "clean"代码在多个级别添加多个子项

Question

我有一个 C# 类，可以在多个级别包含多个子级。

手动添加 child 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>());

我如何使用干净的循环来做到这一点？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:在每个级别我都需要检查该值是否已存在，如果不存在，我将添加它。

感谢您的收听!

我是初学者，所以请保持温柔。

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);
    }
}

你会这样调用它:

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

FillChildren(MyClass, 50);
