c#将字符串转换为JSON错误

本文关键字：JSON 错误 转换 字符串 | 更新日期: 2023-09-27 18:07:14

我为dataTables插件构建了一个数据结构。

构建数据结构的代码如下: 
var response = "{ '"data'": [";
    response = response + "[";
    response = response + "'"Clark, Keith'",";
    response = response + "'"Corporate'",";
    response = response + "'"XXX-XXX-XXXX'",";
    response = response + "'"XXX-XXX-XXXX'",";
    response = response + "'"XXXX@XXXX.com'"";
    response = response + "],";
    response = response + "[";
    response = response + "'"Clark, Keith'",";
    response = response + "'"Corporate'",";
    response = response + "'"YYY-YYY-YYYY'",";
    response = response + "'"YYY-YYY-YYYY'",";
    response = response + "'"YYYY@XXXX.com'"";
    response = response + "]";
    response = response + "] }";
return response;

运行良好，并按预期创建表。当我试图将HTML标记添加到字段时，我遇到了问题。我想使用一个字体awesome图标旁边的名称，以表明这样的状态:

<i class="fa fa-arrow-up" style="color: #00ff00;" aria-hidden="true">

我试着修改我的代码来读:

response = response + "'"<i class='"'"fa fa-arrow-up'"'" style='"'"color: #00ff00;'"'" aria-hidden='"'"true'"'">Clark, Keith'",";

但是现在我收到一个错误，JSON格式不正确。我错过了什么，或者HTML标记不能在JSON结构中使用?

c#将字符串转换为JSON错误

问题是您正在生成一个无效的json字符串字面值。

"<i class=""fa fa-arrow-up"" style=""color: #00ff00;"" aria-hidden=""true"">Clark, Keith",

引号使用反斜杠转义，而不是双引号。

你必须这样做:

"'"<i class='''"fa fa-arrow-up'''" style='''"color: #00ff00;'''" aria-hidden='''"true'''">Clark, Keith'","

这说明了为什么不应该生成这样的字符串。有一些工具可以帮你做到这一点，安全地使用它们。Json.net会很容易地解决这个问题。

var markup = "<i class='"fa fa-arrow-up'" style='"color: #00ff00;'" aria-hidden='"true'">";
var response = new JObject
{
    ["data"] = new JArray
    {
        new JArray
        {
            markup + "Clark, Keith",
            "Corporate",
            "XXX-XXX-XXXX",
            "XXX-XXX-XXXX",
            "XXXX@XXXX.com",
        },
        new JArray
        {
            markup + "Clark, Keith",
            "Corporate",
            "YYY-YYY-YYYY",
            "YYY-YYY-YYYY",
            "YYYY@XXXX.com",
        },
    }
};
return response.ToString();
尽管如此，您不应该在数据中添加标记。数据就是数据，仅此而已。如果您想要影响它的显示方式，则应该将该标记添加到视图中。
