字符串连接附加每个元素文本

我有一个包含n个元素的数组;

var arr =["answerswer1"、"answerswer2","answerswer3"],

我需要这样的结果:

{"text":"answerswer1"},{"text":"answerswer2"},{"text":"answerswer3"}

试过这样做:

string.Join(",", arr);

但是如何给每个元素添加{"text":" "}呢?

var arrayWithText = arr.Select(a => "{'"text'":'"" + a + "'"}");
var result = string.Join(",", arrayWithText);
