JsonSerializerSettings和Asp.Net Core

尝试设置JsonOutputFormatter选项:

var jsonFormatter = (JsonOutputFormatter) options.OutputFormatters.FirstOrDefault(f => f is JsonOutputFormatter);
if (jsonFormatter != null)
{
    jsonFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
}

mvcBuilder.AddJsonOptions(jsonOptions =>
    {
        jsonOptions.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
    });

但是一旦我加上这个,我就得到:

  

MissingMethodException:找不到方法:'Newtonsoft.Json.JsonSerializerSettings Microsoft.AspNet.Mvc.Formatters.JsonOutputFormatter.get_SerializerSettings()'。

我正在使用标准Microsoft.AspNet.Mvc.Formatters.Json (6.0.0-rc1-final)

编辑:安装Newtonsoft.Json 6.0.6(降级所有其他参考资料)解决此问题

任何人都已经拥有了吗? 感谢..

.Net Core 1.0 RTM带有开箱即用的CamelCase格式。这是来自RC2的行为change。但是,如果您需要修改它,请尝试以下代码段:

services.AddMvc()
        .AddJsonOptions(opt =>
    {
        var resolver  = opt.SerializerSettings.ContractResolver;
        if (resolver != null)
        {
            var res = resolver as DefaultContractResolver;
            res.NamingStrategy = null;  // <<!-- this removes the camelcasing
        }
    });

对于dotnet core 1.0.1:

  services
            .AddMvcCore()
            .AddJsonFormatters(o => o...);

我假设你使用的是ASP.Net Core,你应该使用“Microsoft.AspNetCore.Mvc”:

所以替换这个:

"Microsoft.AspNet.Mvc": "6.0.0-rc1-final"

由此:

"Microsoft.AspNetCore.Mvc": "1.0.0-rc2-final"
