问题描述
我有自定义对象的列表列表与LT;插槽>
每个对象插槽都有基因的数组[]
I have a list of custom objects List<Slot>
Each Object Slot has an array of Gene[]
对象插槽
public class Slot
{
private Gene[] _genes;
private int _fitness;
//...
public Slot(int count)
{
_genes = InitializeArray<Gene>(count);
Fitness = 0;
}
public Gene[] getChromosomes()
{
return Genes; //getter method
}
//Helper to init array
static T[] InitializeArray<T>(int length) where T : new()
{
T[] array = new T[length];
for (int i = 0; i < length; ++i)
{
array[i] = new T();
}
return array;
}
}
对象基因
public class Gene
{
private DateTime _date;
private int _tcode;
private byte _availabe;
private byte _duty;
private int _fitness;
//...
public Gene()
{
_fitness = 0;
}
}
主要
private List<Slot> slotsList = new List<Slot>();
//...
//...
private void init_population(int lchromeSize, int lpopulationSize)
{
slotsList.Clear();
Gene[] lstGene = InitializeArray<Gene>(lchromeSize);
//For all slots
for (int i = 0; i < tempInt; i++)
{
//for all genes
for (int ii = 0; ii < lchromeSize; ii++)
{
//assign values to local variables
// and :
lstGene[ii].Date = ldate;
lstGene[ii].Tcode = lteacherCode;
lstGene[ii].Availabe = lavailable;
lstGene[ii].Duty = tempDuty;
lstGene[ii].Fitness = 0;
}
//End ii For
//Add the genes to slotsList
Slot itemtoadd = new Slot(lchromeSize);
itemtoadd.setChromosomes(lstGene);
slotsList.Add(itemtoadd);
}
}
的问题是,在每一个槽的基因是相同的,并且它们引用的最后lstGene []已添加到slotsList
The problem is that in every single Slot the Genes are identical and they reference the last lstGene[] that has been added to slotsList.
在哪里做我搞砸一遍吗?
Where did I mess up it again ?
推荐答案
您需要移动这一行:
Gene[] lstGene = InitializeArray<Gene>(lchromeSize);
为在:您现在重新使用每个插槽的同一阵列的的for(int i = ..
循环 - 这就是你所看到的。
to be inside the for (int i = ..
loop. You are now re-using the same array for every slot - which is what you see.
