获取具有重复C#linq的对象列表

本文关键字：对象 列表 C#linq 获取 | 更新日期: 2023-09-27 18:20:53

我有一个对象列表，如下所示：-

List<EmployeeModel> mList = new List<EmployeeModel>();
        mList.Add(new EmployeeModel { Place = "place1", Time = time1, EmployeeName = "abc" });
        mList.Add(new EmployeeModel { Place = "place2", Time = time2, EmployeeName = "abc" });
        mList.Add(new EmployeeModel { Place = "place3", Time = time3, EmployeeName = "abc" });
        mList.Add(new EmployeeModel { Place = "place1", Time = time4, EmployeeName = "abc" });
        mList.Add(new EmployeeModel { Place = "place2", Time = time5, EmployeeName = "pqr" });
        mList.Add(new EmployeeModel { Place = "place3", Time = time6, EmployeeName = "xyz" });
        mList.Add(new EmployeeModel { Place = "place1", Time = time7, EmployeeName = "pqr" });
        mList.Add(new EmployeeModel { Place = "place2", Time = time8, EmployeeName = "xyz" });
        mList.Add(new EmployeeModel { Place = "place3", Time = time9, EmployeeName = "abc" });

我想首先对列表进行排序，以根据EmployeeName查找重复项。我做如下：-

var dupes = mList.GroupBy(x => new { x.EmployeeName }).Where(x => x.Skip(1).Any());

这给了我一组按EmployeeName分组的值。

我有两个字符串，即placeString和timeString，我想根据EmployeeName值组中的不同值（Time和Place）来填充它们。

大概是这样的：-

EmployeeName - abc
placeString:place1 timeString:time4
placeString:place1 timeString:time2
placeString:place1 timeString:time3
EmployeeName - pqr
placeString:place2 timeString:time5
placeString:place1 timeString:time7
EmployeeName - xyz
placeString:place3 timeString:time6
placeString:place2 timeString:time8

我该如何解决此问题？如有任何帮助，我们将不胜感激。

获取具有重复C#linq的对象列表

预期结果是什么？输出您想要的结果很容易。只需使用foreach:

foreach(var dup in dups)
{
    Console.WriteLine(String.Format("EmployeeName - {0}", dup.Key));
    foreach(EmployeeModel x in dup)
        Console.WriteLine(String.Format("placeString:{0} timeString:{1}", x.Place, x.Time));});
}
