使用 .net MVC 的 jquery Datatables 服务器端处理

Question

我正在尝试让我的数据表实现使用服务器端处理，因为每个表实例都有很多行要返回。我一直在处理在 ajax 调用期间传递的所有查询字符串参数。我增加了允许的查询字符串长度，但查询字符串中“对象”的格式似乎不像我希望的那样配合。

我的控制器签名如下所示：

public JsonResult GetResultDtData(int testCycleID, int draw, int start, int length, Search search, List<Order> order, List<Column> columns)

我已经匹配了那里的每个对象，使其具有与 URL 中发送的相同的字段，并希望它们能够正确映射

以列类为例：

public class Column
{
    public string Data { get; set; }
    public string Name { get; set; }
    public bool Searchable { get; set; }
    public bool Orderable { get; set; }
    public Search Search { get; set; }
}

对于来自 URL 的列对象，如下所示：

columns[0][data]=ExternalID&columns[0][name]=&columns[0][searchable]=true&columns[0][orderable]=true&columns[0][search][value]=&columns[0][search][regex]=false

文档建议所有现代脚本都可以处理这种格式的对象和列表，但对于 MVC 来说是这样吗？我的控制器中有一个对象列表，但这些字段都是空值或默认值。我发现的唯一例子是 php。

想通了，只需要使用字典而不是我创建的类

public JsonResult GetResultDtData(
        int testCycleID, 
        int draw, 
        int start, 
        int length, 
        Dictionary<string, string> search, 
        List<Dictionary<string,string>> order, 
        List<Dictionary<string, string>> columns)

现在看来很明显...
