我们知道List<>类型可以支持对任意类型的存储，我们也可以对其进行排序。现介绍一种较为简单的方法：
1、我们先定义一个类CAttributeFeature，后面我们用List<CAttributeFeature>来存储该类的一个列表，代码如下：
class CAttributeFeature
2: {
string m_strAttributeName { get; set; }
double m_dAttributeFeature { get; set; }
5:
double dFeature)
7: {
this.m_strAttributeName = strName;
this.m_dAttributeFeature = dFeature;
10: }
11:
double dFeature)
13: {
this.m_dAttributeFeature += dFeature;
15: }
16: }
2、我们定义一个函数SortCompare()，对List<CAttributeFeature>进行排序时作为参数使用，代码如下：
#region SortCompare()函数，对List<CAttributeFeature>进行排序时作为参数使用
/// <summary>
/// 对List<CAttributeFeature>进行排序时作为参数使用
/// </summary>
/// <returns></returns>
int SortCompare(CAttributeFeature AF1, CAttributeFeature AF2)
9: {
int res = 0;
if (AF1.m_dAttributeFeature > AF2.m_dAttributeFeature)
12: {
13: res = -1;
14: }
if (AF1.m_dAttributeFeature < AF2.m_dAttributeFeature)
16: {
17: res = 1;
18: }
return res;
20: }
#endregion
3、产生一个List<CAttributeFeature>的对象，将前一步定义的SortCompare()函数做为Sort()方法的参数传入，就可以对List<CAttributeFeature>进行排序了。代码如下：
1: List<CAttributeFeature> listAF = m_nDTreeGenerator1.Chaos_GetUsefulAttributeFeature(Chaos_DTree1);
2:
//按其特征值进行排序
4: listAF.Sort(SortCompare);
