在C#中对List<>进行排序

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：

 
public class CAttributeFeature 
{ 
    public string m_strAttributeName { get; set; } 
    public double m_dAttributeFeature { get; set; } 
  
    public CAttributeFeature(string strName, double dFeature) 
    { 
        this.m_strAttributeName = strName; 
        this.m_dAttributeFeature = dFeature; 
    } 
  
    public void FeatureAdd(double dFeature) 
    { 
        this.m_dAttributeFeature += dFeature; 
    } 
} 
  

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> 
/// <param name="AF1"></param> 
/// <param name="AF2"></param> 
/// <returns></returns> 
private static int SortCompare(CAttributeFeature AF1, CAttributeFeature AF2) 
{ 
int res = 0; 
if (AF1.m_dAttributeFeature > AF2.m_dAttributeFeature) 
{ 
res = -1; 
} 
else if (AF1.m_dAttributeFeature < AF2.m_dAttributeFeature) 
{ 
res = 1; 
} 
return res; 
} 
#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：

 
List<CAttributeFeature> listAF = m_nDTreeGenerator1.Chaos_GetUsefulAttributeFeature(Chaos_DTree1); 
  
//按其特征值进行排序 
listAF.Sort(SortCompare);
