在 .NET 的输出字符串中将列表的所有项目连接在一起 [英] Join together all items of a list in an output string in .NET

问题描述

如何编写一个 LINQ 表达式(或其他任何东西)来从 List 中选择一个项目并将它们连接在一起?

How can I write a LINQ expression (or anything else) that selects an item from a List and join them together?

IList<string> data = new List<string>();

data.Add("MyData1");
data.Add("MyData2");

string result = // Some LINQ query... I try data.Select(x => x + ",");

//result = "MyData1, MyData2"

推荐答案

Just go with (String.Join 方法):

Just go with (String.Join Method):

string joined = String.Join(",", data.ToArray());

但如果必须是 LINQ，您可以尝试:

But if it has to be LINQ, you could try:

string joinedLinq = data.Aggregate((i, j) => i + "," + j);
