C#For循环不向可观察集合添加项

因此，我在使用for循环向可观察集合中添加值时遇到了一个问题。我正在尝试向集合中添加625个值，但它跳过了一些值，我不知道为什么，或者我看不见这个问题

正如在代码中看到的，我有两个集合，一个我已经在构造函数中预先填充了值（这没有问题），另一个我正在尝试从底层填充新值。我有一个for循环，循环625次（同样有效），但不知为什么有些值被跳过了，我不知道为什么

也可以说，我有一个方法，在CellCollection中单击某些值时会发生更改，但这发生在for循环之前，实际上与之无关，但可能值得一提

使用For循环的方法：

     void neighborCalc()
            {
                //calculates alive neighbors and kills or sets cell alive
                for (int i = 0; i < CellCollection.Count; i++)
                {
                    int neighborAliveCounter = 0;

                    //check top
                    if (CellCollection[i].Row > 1)
                    {
                        CellModel topCell = CellCollection.Single(cell => cell.Column == CellCollection[i].Column && cell.Row == CellCollection[i].Row - 1);
                        if (topCell.IsAlive == true)

我不确定为什么它们中的值数量都不相同，并且某些行/列不在缩进点（从tempCollection开始，什么是合乎逻辑的

//decides if to put cell alive or dead
                    if (neighborAliveCounter < 2 || neighborAliveCounter > 3)
                    {
                        tempCollection.Add(new CellModel() { Row = CellCollection[i].Row, Column = CellCollection[i].Column, CellBackgroundColor = new SolidColorBrush(Colors.Transparent), IsAlive = false });
                    }

                    if (neighborAliveCounter == 3)
                    {
