确保JSON键在.NET中为小写

您可以为此创建一个自定义合同解析器。以下合同解析器会将所有密钥转换为小写：

public class LowercaseContractResolver : DefaultContractResolver{    protected override string ResolvePropertyName(string propertyName)    {        return propertyName.ToLower();    }}

用法：

var settings = new JsonSerializerSettings();settings.ContractResolver = new LowercaseContractResolver();var json = JsonConvert.SerializeObject(authority, Formatting.Indented, settings);

威尔导致：

{"username":"Mark","apitoken":"xyzABC1234"}

如果您始终想使用进行序列化

LowercaseContractResolver

public class LowercaseJsonSerializer{    private static readonly JsonSerializerSettings Settings = new JsonSerializerSettings    {        ContractResolver = new LowercaseContractResolver()    };    public static string SerializeObject(object o)    {        return JsonConvert.SerializeObject(o, Formatting.Indented, Settings);    }    public class LowercaseContractResolver : DefaultContractResolver    {        protected override string ResolvePropertyName(string propertyName)        { return propertyName.ToLower();        }    }}

可以这样使用：

var json = LowercaseJsonSerializer.SerializeObject(new { Foo = "bar" });// { "foo": "bar" }
