C# JSON特权绘制无效。在AJAX中，使用jquery数据表在ASP.NET webforms中调用Webmethod

我正在尝试在ASP.NET webforms测试应用程序中实现jquery Datatables.NET的服务器端处理

使用以下代码： Jquery：

（在我的AjaxTest.aspx.cs中）：

班长：

public class Person
    {
        public string Name { get; set; }
        public string FirstName { get; set; }

        public override string ToString()
        {
            return string.Format("{0} {1}", this.FirstName, this.Name);
        }

    }

我的AjaxTest.aspx如下所示：

<table class="table table-hover table-striped" id="PersonsTable">
                <thead>
                    <tr>
                        <th>Vooraam</th>
                        <th>Naam</th>
                    </tr>
                </thead>
                <tbody>

                </tbody>
            </table>

---

有人知道我做错了什么吗？

尝试在静态方法之上添加

[ScriptMethod（UseHttpGet=true，ResponseFormat=ResponseFormat.Json）]

。

你应该参考这个问题，好的，但这并不能回答问题。我找不到一个使用datatables/ajax/c#（asp.net）的工作示例，那么我也帮不了你，因为我对asp一无所知。抱歉，没问题，无论如何，请尝试在静态方法的顶部添加

[ScriptMethod（UseHttpGet=true，ResponseFormat=ResponseFormat.Json）]

public class Person
    {
        public string Name { get; set; }
        public string FirstName { get; set; }

        public override string ToString()
        {
            return string.Format("{0} {1}", this.FirstName, this.Name);
        }

    }

<table class="table table-hover table-striped" id="PersonsTable">
                <thead>
                    <tr>
                        <th>Vooraam</th>
                        <th>Naam</th>
                    </tr>
                </thead>
                <tbody>

                </tbody>
            </table>
