問題描述

我知道有一個屬性可以處理私有設置器，但我有點希望這種行為作為默認值，有沒有辦法做到這一點?除了調整源.如果有這個設置就好了.

I know there's an attribute to handle private setters but I kind of want this behavior as a default, is there a way to accomplish this? Except tweaking the source. Would be great if there was a setting for this.

更新，新答案

我為此編寫了一個源代碼分發 NuGet，它安裝了一個帶有兩個自定義合同解析器的文件:

Updated, new answer

I've written a source distribution NuGet for this, that installs a single file with two custom contract resolvers:

• PrivateSetterContractResolver
• PrivateSetterCamelCasePropertyNamesContractResolver

安裝 NuGet 包:

Install-Package JsonNet.ContractResolvers

然后只需使用任何解析器:

Then just use any of the resolvers:

var settings = new JsonSerializerSettings
{
    ContractResolver = new PrivateSetterContractResolver()
};

var model = JsonConvert.DeserializeObject<Model>(json, settings);

有兩種方法可以解決問題.

There are two alternatives that can solve the problem.

Alt 1:在反序列化器上

ContractResolver.DefaultMembersSearchFlags =
                             DefaultMembersSearchFlags | BindingFlags.NonPublic;

默認的序列化選項支持所有類型的類成員.因此，此解決方案將返回所有私有成員類型，包括字段.我只對支持私人二傳手感興趣.

The default serialization option supports all types of class member. Therefore this solution will return all private members types including fields. I'm only interested in also supporting private setters.

Alt2:創建自定義 ContractResolver:

因此這是更好的選擇，因為我們只檢查屬性.

Therefore this is the better options since we just check the properties.

public class SisoJsonDefaultContractResolver : DefaultContractResolver 
{
    protected override JsonProperty CreateProperty(
        MemberInfo member,
        MemberSerialization memberSerialization)
    {
        //TODO: Maybe cache
        var prop = base.CreateProperty(member, memberSerialization);

        if (!prop.Writable)
        {
            var property = member as PropertyInfo;
            if (property != null)
            {
                var hasPrivateSetter = property.GetSetMethod(true) != null;
                prop.Writable = hasPrivateSetter;
            }
        }

        return prop;
    }
}
