根据数值差异对数组进行排序(Sort Array on on Value Difference)

 例如，我有一个数组  
string[] stArr= new string[5] { "1#3", "19#24", "10#12", "13#18", "20#21" };
 
 我想对这个数组进行排序  
3-1=2;
24-19=5;
12-10=2;
18-13=5;
21-20=1;
 
 排序结果应该是这样的  
string[] stArr= new string[5] { "20#21", "1#3", "10#12", "13#18", "20#21" };
 
 我必须为所有可能的情况找到解决方案。  
 
  1>数组的长度不固定（数组中的元素）  
  2> y总是大于x， eg x#y  
  3>我不能使用列表  

I Have An Array,for example 
string[] stArr= new string[5] { "1#3", "19#24", "10#12", "13#18", "20#21" };
 
i want to sort this array on  
3-1=2;
24-19=5;
12-10=2;
18-13=5;
21-20=1;
 
and the sorting result should be like 
string[] stArr= new string[5] { "20#21", "1#3", "10#12", "13#18", "20#21" };
 
I have to find the solution for all possible cases. 
 
 1>length of the array is not fixed(element in the array) 
 2>y always greater than x e.g x#y 
 3> i can not use list

 您应该改用SortDescriptions集合。 此集合允许您提供如何在视图中对项目进行排序的一组规则。  
 你可以在这里找到一个很好的例子来说明如何使用它： https : //stackoverflow.com/a/19952233/6597895  
public static void SortDataGrid(DataGrid dataGrid, int columnIndex = 0, ListSortDirection sortDirection = ListSortDirection.Ascending)
{
    var column = dataGrid.Columns[columnIndex];

    // Clear current sort descriptions
    dataGrid.Items.SortDescriptions.Clear();

    // Add the new sort description
    dataGrid.Items.SortDescriptions.Add(new SortDescription(column.SortMemberPath, sortDirection));

    // Apply sort
    foreach (var col in dataGrid.Columns)
    {
        col.SortDirection = null;
    }
    column.SortDirection = sortDirection;

    // Refresh items to display sort
    dataGrid.Items.Refresh();
}

You should work with SortDescriptions collection instead. This collection allows you to provide set of rules of how to sort items in the view.  
You can find a good example on how to use it here: https://stackoverflow.com/a/19952233/6597895 
public static void SortDataGrid(DataGrid dataGrid, int columnIndex = 0, ListSortDirection sortDirection = ListSortDirection.Ascending)
{
    var column = dataGrid.Columns[columnIndex];

    // Clear current sort descriptions
    dataGrid.Items.SortDescriptions.Clear();

    // Add the new sort description
    dataGrid.Items.SortDescriptions.Add(new SortDescription(column.SortMemberPath, sortDirection));

    // Apply sort
    foreach (var col in dataGrid.Columns)
    {
        col.SortDirection = null;
    }
    column.SortDirection = sortDirection;

    // Refresh items to display sort
    dataGrid.Items.Refresh();
}
