简介 list泛型自定义排序示例_实用技巧_
复制代码 代码如下:
static void Main(string[] args)
{
Employee employee = new Employee();
//设置初始值
List
employeeList.Add(new Employee() { EmpId = "001", EmpName = "Tony" });
employeeList.Add(new Employee() { EmpId = "002", EmpName = "Mack" });
employeeList.Add(new Employee() { EmpId = "003", EmpName = "Jon" });
employeeList.Add(new Employee() { EmpId = "004", EmpName = "Dawei" });
employeeList.Add(new Employee() { EmpId = "005", EmpName = "Jack" });
employeeList.Add(new Employee() { EmpId = "006", EmpName = "Abby" });
employeeList.Add(new Employee() { EmpId = "007", EmpName = "Carrie" });
//指定置前排序元素
List
toSortList.Add(new Employee() { EmpId = "003", EmpName = "Jon" });
toSortList.Add(new Employee() { EmpId = "005", EmpName = "Jack" });
toSortList.Add(new Employee() { EmpId = "007", EmpName = "Carrie" });
//自定义 排序委托
employeeList.Sort((Employee x, Employee y) => (toSortList.Count(e => e.EmpId == y.EmpId) - toSortList.Count(e => e.EmpId == x.EmpId)));
}
public class Employee
{
public string EmpId
{
get;
set;
}
public string EmpName
{
get;
set;
}
}
经过排序后将原本list中按001，002,003，排列的元素排序为003,005,007,001,002,004.。。。将指定的003,005,007，排列在List最前
