将两个不同的列表导出到一个字符串中 [英] Export two different list into one string

问题描述

我想在ASP.NET的单个CSV文件中导出两个不同的列表

I have two different lists I want to export in single CSV file in ASP.NET

string listToString1= string.Join(",", list1.ToArray());
string listToString2= string.Join(",", list2.ToArray());
string finalstring = "Collection ID" + listToString1+ "," + "Collection Title" + listToString2;

return File(new System.Text.UTF8Encoding().GetBytes(finalstring), "text/csv", "abcd.csv");

在这里，我得到的输出如下:

Here i am getting output like:

集合ID，id1，id2，id3

Collection ID , id1,id2,id3

馆藏标题，Title1，Title2，Title3

Collection Title, Title1,Title2,Title3

但是我希望输出像:

馆藏ID，馆藏标题id1，Title1 id2， Title2 id3，Title3

Collection Id, Collection Title id1 , Title1 id2 , Title2 id3 , Title3

此处的集合ID在同一列中，而集合的标题在同一列中

Here collection ids are in same column and collection titles are in same column

推荐答案

您需要的是

What you need is a Zip method:

List<string> list1 = new List<string>() { "Collection ID", "id1", "id2" , "id3" };
List<string> list2 = new List<string>() { "Collection Title", "Title1", "Title2", "Title3" };
var result = string.Join(" ",list1.Zip(list2, (f,l) => f + "," + l));

您需要确保已将System.Linq添加到using指令中

You need to make sure that you've added the System.Linq to your using directive though
