根據對象成員對C＃數組進行排序？

Question

我有一個2（雙）數組成員的構造函數：

構造函數[i] .x和構造函數[i] .y（其中，i是元素數）

如何對x成員進行排序：constructor []。x？

Answer 1

有了LINQ，

constructor = constructor.OrderBy(a => a.x).ToArray();

沒有LINQ

class CustomClass
{
    public double x;
    public double y;
}

public class CustomComparer : IComparer<CustomClass>
{
    private CustomComparer() { }

    public static CustomComparer Instance { get { return _SingeltonInstance; } }

    private static CustomComparer _SingeltonInstance = new CustomComparer();

    public int Compare(CustomClass a, CustomClass b)
    {
        return a.x.CompareTo(b.x);
    }
}

public class myCode
{
    public void SomeFuction(CustomClass[] myClass)
    {
         //myClass is unsorted here;
         Array.Sort(myClass, CustomComparer.Instance);
         //myClass is sorted here;
    }
}
