使用 Newtonsoft.Json 将 属性 添加到 json 的指定位置
Adding a property into specified location into json using Newtonsoft.Json
我有一个追随者JSON。我添加了 2 个双引号 ，这样我就可以在 c# 中将其声明为 string 变量，实际上它包含属性的一次双引号。
完整的示例代码在 fiddle.
我正在使用 Newtonsoft，但也可以使用 System.Text.Json，因此我们将不胜感激。

我想添加验证，如果我的 JSON 的键与我列表中的项目匹配，则需要它的子键。
我有三种情况，它们根据下面代码中的注释进行了解释。
public static void Main()
{
Console.WriteLine("BEFORE MANDATORY");
List<string> mandatoryKeys = new List<string>();
//Scenario 1: Has validate key but not required key in json, so we need to add "required": true
//inside existing "validate"
mandatoryKeys.Add("Activity.ActivityDate");
//Scenario 2: Does not have both validate and required so will need to have both "validate" and its child "required"
mandatoryKeys.Add("Activity.Duration");
//Scenario 3: Has both "validate" and "required" so we should not add it again
mandatoryKeys.Add("Activity.AgencyActivityCategoryId");
//Scenario 2 again for double checking
mandatoryKeys.Add("Activity.AgencyActivityAttendanceId");
var data = JObject.Parse(GetRawJson());
Console.WriteLine(data);
for(int i = 0; i < mandatoryKeys.Count(); i++)
IterateJson(data, mandatoryKeys[i]);
Console.WriteLine("AFTER MANDATORY");
Console.WriteLine("XXXXXXXXXXXXXXX");
Console.WriteLine(data);
Console.ReadLine();
}
下面显示JSON迭代函数。
static void IterateJson(JToken value, string mandatoryFieldKey)
{
//if more than 0 - so value is object or array and we have to call this method for each property
if (value.Values().Count() != 0)
{
foreach (var item in value.Values().ToList())
{
IterateJson(item, mandatoryFieldKey);
}
}
else if (value.ToString() == mandatoryFieldKey)
{
Console.WriteLine("HELLO");
//check if above "required" property exists
if (value.Parent.Parent is JObject jObject && jObject["validate"] == null)
{
Console.WriteLine(value);
jObject.Add("validate", JObject.FromObject(new { required = true })); //add required property
}
}
}
我的最终 JSON 应该如下所示。

我无法实现所有三种方案。有人可以看看并提供解决方案吗？此外，如果有更好的方法来完成此操作，请提供该方法的解决方案。
我创建了一个 fiddle 以便于帮助我。
我已经设法解决了这个问题，在这里发布了一个解决方案，以防它能帮助到其他人。我已经意识到 json 中的所有控件都是组件 object/array 的一部分，因此我们可以使用 JSONPath，请参阅 link 了解更多 details。下面的代码已经成功了：
public void IterateJson(JObject obj, string mandatoryFieldKey)
{
JToken jTokenFoundForMandatoryField = obj.SelectToken
("$..components[?(@.key == '" + mandatoryFieldKey + "')]");
//Now we convert this oken into an object so that we can add properties/objects in it
if (jTokenFoundForMandatoryField is JObject jObjectForMandatoryField)
{
//We check if validate already exists for this field, if it does not
//exists then we add validate and required property inside the if condition
if (jObjectForMandatoryField["validate"] == null)
jObjectForMandatoryField.Add("validate",
JObject.FromObject(new { required = true })); //add validate and required property
else
{
//If validate does not exists then code comes here and
//we convert the validate into a JObject using is JObject statement
if (jObjectForMandatoryField["validate"] is JObject validateObject)
{
//We need to check if required property already exists,
//if it does not exists then we add it inside the if condition.
if (validateObject["required"] == null)
{
validateObject.Add("required", true); //add required property
}
}
}
}
