从以上代码中，我们构造了两个比较器，分别是【出资人】，【余额缴付期限】
我们构造一个工厂方法，来方便调用
代码
/// <summary>
/// 对象排序比较器工厂
/// </summary>
public class ContributivePerson_SortComparerFactory
{
/// <summary>
///
/// </summary>
/// <param name=”FieldName”></param>
/// <returns></returns>
public IComparer<TB_WEB_NZ_INVESTMENT> GetSortComparer(string FieldName, ESortType eSortType)
{
IComparer<TB_WEB_NZ_INVESTMENT> IComparer = null;
switch (FieldName)
{
case “BALDEPER”://余额缴付期限
IComparer = new ContributivePerson_BALDEPER_Comparer(eSortType);
break;
case “INV”://投资人
IComparer = new ContributivePerson_INV_Comparer(eSortType);
break;
}//switch
return IComparer;
}
}//class
下面我们进行运用,这个方法是一个Webservice接口端的新写的方法，我们看见红色代码段是排序块，绿色注解是过滤代码块（代码已经略去）
代码
/// <summary>
/// 分页功能的表格填充服务端(带排序)
/// </summary>
/// <param name=”FlowID”></param>
/// <param name=”PageCount”>每页数目</param>
/// <param name=”CurrentPage”>当前页</param>
/// <param name=”SortType”>排序类型:”ASC” ,”DESC”</param>
/// <returns></returns>
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string Load_ContributivePerson_Table_Sort(string FlowID, int PageCount,
int CurrentPage, string SortType, string SortFieldName)
{
List<TB_WEB_NZ_INVESTMENT> list = new List<TB_WEB_NZ_INVESTMENT>();
list = objBusinessFacade.GetTB_WEB_NZ_INVESTMENT_CollectionByFlowID(FlowID);
ContributivePerson_SortComparerFactory objFactory = new ContributivePerson_SortComparerFactory();
IComparer<TB_WEB_NZ_INVESTMENT> objSort = null;
if (SortType.ToUpper().Trim() == “ASC”)
{
objSort = objFactory.GetSortComparer(SortFieldName,ESortType.ASC);
}
else if (SortType.ToUpper().Trim() == “DESC”)
{
objSort = objFactory.GetSortComparer(SortFieldName, ESortType.DESC);
