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：

1: public class CAttributeFeature

2: {

3:     public string m_strAttributeName { get; set; }

4:     public double m_dAttributeFeature { get; set; }

5: 

6:     public CAttributeFeature(string strName, double dFeature)

7:     {

8:         this.m_strAttributeName = strName;

9:         this.m_dAttributeFeature = dFeature;

10:     }

11: 

12:     public void FeatureAdd(double dFeature)

13:     {

14:         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：

1: #region SortCompare()函数，对List
      
       进行排序时作为参数使用
      

2: /// 

3: /// 对List
      
       进行排序时作为参数使用
      

4: /// 

5: /// 

6: /// 

7: /// 
      

8: private static int SortCompare(CAttributeFeature AF1, CAttributeFeature AF2)

9: {

10: int res = 0;

11: if (AF1.m_dAttributeFeature > AF2.m_dAttributeFeature)

12: {

13: res = -1;

14: }

15: else if (AF1.m_dAttributeFeature < AF2.m_dAttributeFeature)

16: {

17: res = 1;

18: }

19: return res;

20: }

21: #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
      
        listAF = m_nDTreeGenerator1.Chaos_GetUsefulAttributeFeature(Chaos_DTree1);
      

2: 

3: //按其特征值进行排序

4: listAF.Sort(SortCompare);
