我已经写了一个简单的方法,接收一个通用的,我想放入一个ArrayList使用ArrayList.Add()方法。但是我发现,当我去添加一个与ArrayList中的前一个项目具有相同类型的新项目时,这个新项目将覆盖以前项目的各个属性。C#ArrayList.Add()覆盖以前的对象添加
下面是代码,它的基本和相当尴尬,我似乎无法纠正这个覆盖问题。
public class ChromosomeTree<T>
{
private GeneNode<T> root;
private ArrayList children = new ArrayList();
private int depMax;
string stemp;
public ChromosomeTree()
{
root = null;
}
public virtual void Clear()
{
root = null;
}
public GeneNode<T> Root
{
get
{
return root;
}
set
{
root = value;
}
}
public int MaxDepth
{
get
{
return depMax;
}
set
{
depMax = value;
}
}
public ArrayList Children
{
get
{
return children;
}
}
public GeneNode<T> lastChild()
{
return (GeneNode<T>)this.Children[this.Children.Count - 1];
}
public void addFull(GeneNode<T> node)
{
//check if the chromosome tree has a root if not add the first node as the chromosomes root
if (this.Root == null)
{
this.Root = node;
children.Add(node);
stemp += " " + node.Value;
}
else
{
for (int i = 0; i <= this.Children.Count - 1; i++)
{
GeneNode<T> parent = (GeneNode<T>)this.Children[i];
//check to ensure maxDepth of chromosome tree is not exceeded
if (parent.Depth != this.MaxDepth)
{
//check to see if the current node stil has room for another node to be added to it
if ((parent.Children == null) || (parent.Children[1] == null))
{
children.Add(node);
parent.Add(node);
stemp += " " + node.Value;
break;
}
}
else
{
break;
}
}
}
}
public override string ToString()
{
string chromosome = String.Empty;
foreach(GeneNode<Gene> gene in this.Children)
{
chromosome += " " + gene.Value.GeneValue.ToString();
}
return chromosome;
}
}
我很确定它是一个简单的错误,但我看了这么久,我不能看到树木。任何想法将不胜感激。
非常感谢提前。

这里是利用这个类的代码。
编辑:改写时发生之后,该方法已经执行其逻辑
class SimpleChromosome
{
Random rand = new Random();
Gene funcGene = new Gene();
Gene termGene = new Gene();
private string sChromosome;
private int currentdepth;
private string grownChromosome()
{
return sChromosome;
}
public ChromosomeTree<Gene> fullChromosome()
{
ChromosomeTree<Gene> chromosone = new ChromosomeTree<Gene>();
//chromosone.MaxDepth = rand.Next(1, 5);
chromosone.MaxDepth = 1;
int maxGenes = (int)Math.Pow(2, chromosone.MaxDepth + 1) - 1;
for (int i = 0; i <= chromosone.MaxDepth; i++)
{
int numNodesForLevel = (int)Math.Pow(2, i);
int numNodesOnLevel = 0;
for (int j = 0; j < numNodesForLevel; j++)
{
if (currentdepth != chromosone.MaxDepth)
{
funcGene.GenerateValue(GeneType.Function);
GeneNode<Gene> geneNode = new GeneNode<Gene>(funcGene);
sChromosome += " " + geneNode.Value;
chromosone.addFull(geneNode);
numNodesOnLevel++;
}
else
{
termGene.GenerateValue(GeneType.Terminal);
GeneNode<Gene> geneNode = new GeneNode<Gene>(termGene);
sChromosome += " " + geneNode.Value;
chromosone.addFull(geneNode);
numNodesOnLevel++;
}
if ((numNodesForLevel == numNodesOnLevel) && (currentdepth != chromosone.MaxDepth))
{
currentdepth++;
}
}
}
currentdepth = 0;
//Console.WriteLine("Before ADD :" + sChromosome);
sChromosome = "";
return chromosone;
}
}
可能有助于张贴您正在使用这个类,其中的代码。我想知道你是否只是一直将相同的实例添加到列表中。 – Nick 2011-03-07 12:42:31
为什么你使用'ArrayList'给定你可以清楚地使用泛型,不感兴趣? – 2011-03-07 12:43:53
您是否想要为每个孩子添加一份参考指南到根目录? – smartcaveman 2011-03-07 12:52:36
