我目前停留在一个问题,我有2个清单,我想根据从第一个列表中的值第二列表进行排序,下面是一个例子:
I'm currently stuck at a problem where I have 2 Lists, and I want to sort the second List according to a value from the first List, here is an example:
public class data
{
public string Name{get; set;}
public int ID{get; set}
}
public class dataToSort
{
public int ID{get; set;}
public string retrievedData{get; set}
public string timeStamp{get; set}
}
因此,可以说我有2个List对象,一个用于数据,一个用于dataToSort,下面的内容:
So lets say I have 2 List objects, one for data and one for dataToSort, their contents below:
data: "Alpha", "80" dataToSort: "21", "XA", "YA"
"Beta", "47" "47", "XB", "YB"
"Charlie", "153" "80", "XC", "YC"
"Delta", "21" "153","XD", "YD"
所以,我想要做的就是让dataToSort相等于ID的数据,这样的顺序依次为:
So what I want to do is to make the order of dataToSort equal to the order of the IDs in data, like this:
dataToSort: "80", "XC", "YC"
"47", "XB", "YB"
"153","XD", "YD"
"21", "XA", "YA"
我曾尝试使用Google的一种方式来排序这些,但所有的LINQ语法混淆了我,我必须因类的每个对象:(我能想到的唯一途径的差异问题是要有一个for循环得到一个列表的ID和指标做一些像冒泡排序,但它太麻烦了,也没有效率。帮助是极大的AP preciated!
I have tried googling for a way to Sort these but all the LINQ syntax confuses me and I have problems due to the difference in classes of each object :( The only way I can think of is to have a for loop to get the index of one List's ID and do something like a bubble sort, but its too much of a hassle and also inefficient. Help is greatly appreciated!
您可以加入的ID两个列表:
You can join the two lists on the IDs:
var query = from x in data
join y in dataToSort on x.ID equals y.ID
select y;
var result = query.ToList();
这保持了第一列表的顺序数据
。
This keeps the order of the first list data
.
您还可以轻松地将二者结合起来的列表是这样的:
You can also easily combine the two lists this way:
var query = from x in data
join y in dataToSort on x.ID equals y.ID
select new
{
x.Name,
x.ID,
y.retrievedData,
y.timeStamp,
};
var result = query.ToList();
