I have sample code but this return character by character from C# array, I want to return in normal way like word by word in javascript array;
我有示例代码，但是这个从 C# 数组中逐个字符地返回，我想以正常方式返回，例如在 javascript 数组中逐字返回；

后面的 C# 代码：
public string[] names = { "John", "Pesho", "Maria"};
public JavaScriptSerializer javaSerial = new JavaScriptSerializer();
javascript code:
javascript代码：
<script>
var a = '<%= this.javaSerial.Serialize(this.names) %>';
for (var i = 0; i < a.length; i++) {
console.log(a[i]);
}

This script return all words from "names" array in single char array . I want to return in normal way like ["John"] ["Pesho"] ...
此脚本以单个字符数组的形式返回“名称”数组中的所有单词。我想以正常的方式返回，例如 ["John"] ["Pesho"] ...

Replace
代替
var a = '<%= this.javaSerial.Serialize(this.names) %>';
with
和
var a = <%= this.javaSerial.Serialize(this.names) %>;
You were putting the resulting JSON into a javascript string, which would result in your example output iterating through each character of the Serializecall.
您将生成的 JSON 放入一个 javascript 字符串中，这将导致您的示例输出遍历Serialize调用的每个字符。

your c# code will return a string, you have to first parse the string using JSON.parse, and then iterate through it:
您的 c# 代码将返回一个字符串，您必须首先使用 JSON.parse 解析该字符串，然后对其进行迭代：
var a = JSON.parse('<%= this.javaSerial.Serialize(this.names) %>');
for (var i = 0; i < a.length; i++) {
console.log(a[i]);
}
or maybe as @Matthew said, don't put quotes around it, so you won't have to parse it.
或者正如@Matthew 所说，不要在它周围加上引号，这样你就不必解析它。
