在 C# 中创建逗号分隔的字符串 [英] Create a comma-separated strings in C#

问题描述

我有一个包含许多值的对象，其中一些(不是对象中的所有值)需要放入 CSV 字符串.我的方法是这样的:

I have an object which holds many values, and some of them (not all values from the object) need to be put in a CSV string. My approach was this:

string csvString = o.number + "," + o.id + "," + o.whatever ....

有没有更好、更优雅的方式?

Is there is a better, more elegant way?

推荐答案

如果你把所有的值放在一个数组中，至少你可以使用string.Join.

If you put all your values in an array, at least you can use string.Join.

string[] myValues = new string[] { ... };
string csvString = string.Join(",", myValues);

您也可以使用 string.Join 的重载，将 params string 作为第二个参数，如下所示:

You can also use the overload of string.Join that takes params string as the second parameter like this:

string csvString = string.Join(",", value1, value2, value3, ...);
