objectid ID { Get ; set ;} string title { Get ; set ;} int depth { Get ; set ;} string path { Get ; set ;} From the class definition, we can see that the storage structure of the Tree node mainly has four items: ID is a unique number, title is the node name, and depth is the depth of the node, PATH is the full path of the node. The following describes the subnode query operations. The Code is as follows: Private String List (httpcontext context ){ String Nodeid = contex

LINQ to JSON is used to manipulate JSON objects. You can use it to quickly query, modify, and create JSON objects. When the JSON object content is complex and we only need a small subset of the data, consider using LINQ to JSON to read and modify portions of the data instead of deserializing all.two. Creating JSON arrays and objectsBefore you make LINQ to JSON, let's first look at the classes used to manipulate LINQ to JSON. Class name Description Jobject

able to solve this problem on the server side. In the source code of Ext.Direct.dll, the author found that the definition type of "result" of Directresponse class is an object, so the author modifies the return data type of the method called by the client in the example to Jobject. However, an error occurs when you execute the following statement: Return JsonConvert. SerializeObject (response); It seems that there needs to be modified, so the author of the Directprocessor class in the above sen

order to keep the category at the top, it is best to exclude it during the query and add it to the result. The code is modified as follows: Q = Dc. t_category.where (M => M. hierarchylevel = 0 M. categoryid! = 10000 M. State = 0). orderby (M => M. Title ); Now we need to write data to Ja. Because we need to write objects in the same format multiple times, it is better to separate the writing objects into a method. The Code is as follows: Privatejobject writenode (int id, string text, int par

good choice to overload this method. The Code is as follows: Publicstatic JObject WriteJObjectResult (bool success, int total, string message, JArray data) { Return new JObject { NewJProperty ("success", success ), New JProperty ("total", total ), New JProperty ("Msg", message ), New JProperty ("data", data) }; } Now you can complete the code for the List metho

records, MSG: error message, Data: An array composed of records on the current page } In the structure, success indicates whether the returned results are successful. If it fails, you can use MSG to obtain the error message. If it succeeds, it reads data from the data. The total in the structure is very important. The client will calculate the number of pages based on this value, so it must be returned correctly, otherwise the page will be messy. To adapt the writejobjectresult method created

); String name = jsonObj ["name"]. ToString (); String age = jsonObj ["age"]. ToString (); String city = (JObject) jsonObj ["addr"]) ["city"]. ToString (); String province = (JObject) jsonObj ["addr"]) ["province"]. ToString (); Why is this json dynamic? For example, you can enter a json file, such as {"name": "lily", "age": 23, "addr": {"city": guangzhou, "province ": guangdong}; then let you enter an object, such as city, and then the system will output the guangzhou value. In this case, json
