Question

在从PascalCase（默认）到camel的下列JsonFormatter的ContractResolver配置之后，我在驼峰的情况下获得了以下Json输出。

但是，我更喜欢在小写和下划线中实现Json输出（大写应该用下划线替换）。有任何想法吗？：）

protected void Application_Start()
{
    GlobalConfiguration.Configure(WebApiConfig.Register);

    EnableCamelCase();
}

private void EnableCamelCase()
{
    HttpConfiguration config = GlobalConfiguration.Configuration;
    config.Formatters.JsonFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
    config.Formatters.JsonFormatter.UseDataContractJsonSerializer = false;
}

类属性

public int MenuId { get; set; }
public byte TypeId { get; set; }
public string MenuName { get; set; }
public string Description { get; set; }
public string Tooltip { get; set; }
public byte? Minimum { get; set; }
public byte? Maximum { get; set; }
public bool CanMultiSelect { get; set; }
public byte SortOrder { get; set; }

Camel Case Json输出

"items": [
    {
      "menuId": 82,
      "typeId": 1,
      "menuName": "dsf",
      "description": "sdafsdafsd",
      "tooltip": null,
      "minimum": null,
      "maximum": null,
      "canMultiSelect": false,
      "sortOrder": 0
    },
    {
      "menuId": 83,
      "typeId": 1,
      "menuName": "sdfad",
      "description": "fsdfda",
      "tooltip": null,
      "minimum": null,
      "maximum": null,
      "canMultiSelect": false,
      "sortOrder": 0
    }
]}

首选输出

"items": [
    {
      "menu_id": 82,
      "type_id": 1,
      "menu_name": "dsf",
      "description": "sdafsdafsd",
      "tooltip": null,
      "minimum": null,
      "maximum": null,
      "can_multi_select": false,
      "sort_order": 0
    },
    {
      "menu_id": 82,
      "type_id": 1,
      "menu_name": "dsf",
      "description": "sdafsdafsd",
      "tooltip": null,
      "minimum": null,
      "maximum": null,
      "can_multi_select": false,
      "sort_order": 0
    }

您需要创建一个继承自DefaultContractResolver的自定义ContractResolver。见the Newtonsoft documentation。然后，您可以循环遍历属性名称中的字符，并根据需要插入下划线/使字符小写。
