将列表字符串从C#传递到JavaScript

using System.Web.Script.Serialization;

List<string> myList = new List<string> { "item1", "item2", "item3" };
JavaScriptSerializer serializer = new JavaScriptSerializer();
string jsonString = serializer.Serialize(myList);

var jsonArray = JSON.parse(jsonString);

List<string> myList = new List<string> { "item1", "item2", "item3" };
string joinedString = string.Join(",", myList);

var array = joinedString.split(",");

List<string> myList = new List<string> { "item1", "item2", "item3" };
string jsonString = new JavaScriptSerializer().Serialize(myList);
Response.Write(jsonString);

var xhr = new XMLHttpRequest();
xhr.open('GET', 'your_csharp_endpoint', true);
xhr.onreadystatechange = function() {
  if (xhr.readyState === 4 && xhr.status === 200) {
    var jsonArray = JSON.parse(xhr.responseText);
  }
};
xhr.send();
