使用Newtonsoft.Json将属性添加到json的指定位置

使用Newtonsoft.Json将属性添加到json的指定位置

我设法解决了这个问题，在这里发布了一个解决方案，以防它可以帮助其他人。我已经意识到json中的所有控件都是组件对象/数组的一部分，因此我们可以使用

JSONPath

，请参阅链接以获取更多详细信息。以下代码可以解决问题：

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 pre 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  }         }     }      }     }
