C#简单实现泛型数组QSort

Talk is cheap,show me the code

public class UIPanel
{
    public int depth;
}

public class Test
{
    /***************快速排序功能****************/
    public delegate int QSortCompareFunction<T>(T a,T b);
    public static void QSort<T>(T[] array,QSortCompareFunction<T> compareFunc)
    {
        //排序算法: 插入排序
        for(int i = 1; i < array.Length; i++)
        {  
            T t = array[i];  
            int j = i;
            while( (j>0) && compareFunc(array[j-1] , t) > 0 )
            {
                array[j] = array[j-1];
                --j;
            }
            array[j] = t;
        }
    }
    /************快速排序功能结束***************/

    static int UIPanelSortBy(UIPanel a,UIPanel b)
    {
        if(a.depth > b.depth)return 1;
        if(a.depth < b.depth)return -1;
        return 0;
    }

    static void PrintArray(UIPanel[] panels)
    {
        System.Console.Write("[");
        for(int i = 0; i < panels.Length; i++)
        {
            if(i != 0)System.Console.Write(",");
            System.Console.Write(panels[i].depth);
        }
        System.Console.Write("]\n");
    }

    static void Main(string[]args)
    {
        UIPanel[] panels = {
            new UIPanel(){depth = 6},new UIPanel(){depth = 2},new UIPanel(){depth = 1}
            ,new UIPanel(){depth = 4},new UIPanel(){depth = 5},new UIPanel(){depth = 3}
            ,new UIPanel(){depth = 2},new UIPanel(){depth = 5},new UIPanel(){depth = 7}
        };

        PrintArray(panels);

        QSort<UIPanel>(panels,UIPanelSortBy);

        PrintArray(panels);
    }
}
