Решения на трета задача от лаба за Design Patterns 19.08.2015
Здравейте колеги, може ли да дадете идеи за кода на DomBuildera(3та задача от лаба)?
Ето ти Main-a: добавил съм ред Console.WriteLine(html.Display(0)), за да ти се визуализира output-a на конзолата.
namespace DOMBuilder
{
using System;
using System.IO;
using Composite.Element;
public class Program
{
public static void Main()
{
Element html = new Element("html",
new Element("head"),
new Element("body",
new Element("section",
new Element("h2"),
new Element("p"),
new Element("span")),
new Element("footer")));
Console.WriteLine(html.Display(0));
File.WriteAllText("index.html", html.Display(0));
}
}
}
Thanks колега, ето го и моето решение:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.CompilerServices;
using System.Text;
namespace DOMBuilder
{
public class Element
{
private string type;
private ICollection<Element> children;
public Element(string type, params Element[] children)
{
this.Type = type;
this.children = new List<Element>();
for (int i = 0; i < children.Length; i++)
{
this.children.Add(children[i]);
}
}
public string Type
{
get { return this.type; }
set { this.type = value; }
}
public void Add(Element element)
{
this.children.Add(element);
}
public void Remove(Element element)
{
if (this.children.Contains(element))
{
this.children.Remove(element);
}
else
{
throw new ArgumentNullException("The element doesn't exist in the children collection.");
}
}
public string Display(int deapth = 0)
{
StringBuilder sb = new StringBuilder();
sb.AppendLine(string.Format("{0}<{1}>", new string(' ', deapth), this.Type.ToString()));
if (this.children.Count > 0)
{
foreach (var element in this.children)
{
sb.AppendLine(element.Display(deapth + 1));
}
}
sb.Append(string.Format("{0}</{1}>", new string(' ', deapth), this.Type.ToString()));
return sb.ToString();
}
}
}
