![]()
It has a "nested" array (set of key-value pairs) for "CityAliases". #Json compare newtonsoft fullSee the first message in this thread to see the full JSON being retrieved. Thanks to help from ftornero, I was able to work through my question. IF CONFIRM('AliasName = ' FORMAT(Value)) THEN <<-Returns NULL Value := JSONObject2.SelectToken('Item.CityAliasName') ![]() JsonObject2 := JSONObject.SelectToken('item.CityAliases') I can move the "City Aliases" key and all its sub-values into a separate JsonObject, but when I try to query for values within each "Item" in a FOREACH loop, I get NULL, e.g. Now I want to loop through the "CityAliases" OK, the above line worked great for the keys in the "first level" like "Latitude". ![]() Latitude must to be a variant variable and deal with it. Latitude := JObject.SelectToken('item.Latitude') #Json compare newtonsoft how toString rssTitle = (string)rss ĭoes anyone know how to read a specific key-value pair in C/AL that is "nested" inside another key? But the syntax doesn't translate to C/AL. you don't have to parse the entire string and check each key-value pair for the one you want. There are numerous examples out on the web for C# or Javascript that say this can be done, i.e. IF JObject.TryGetValue('item,Longitude',JToken) THEN BEGIN. IF JObject.TryGetValue('',JToken) THEN BEGIN. The value returned is the entire Json string as above.īut I want to retrieve ONLY the "Latitude" and "Longitude" key-value pairs. JProperty := JObject.Property(propertyName) IF JObject.TryGetValue('item',JToken) THEN BEGIN Has anyone used the DotNet library to read specific key/value pairs from a JSON string? C Programming Language Fundamentals By Kenny Kerr (Pluralsight)Ĭ C is considered to be one of the most powerful, fastest, and toughest programming languages.There are a number of posts here about parsing JSON files, but none that use the DotNet Newtonsoft JSON library.C in 4 hours (FREE Youtube Course by FreeCodeCamp).Introduction to Programming in C Specialization (Coursera).C Programming For Beginners - Master the C Language (Udemy).Where can I learn C?ġ0 Best C Programming Courses for Beginners Modern applications add new features implemented using high-level languages, but a lot of their existing functionalities use C. Even Python, one of the most popular languages, was built on C. A lot of applications, including Microsoft Windows, run on C. The main features of the C language include low-level memory access, a simple set of keywords, and a clean style, these features make C language suitable for system programmings like an operating system or compiler development.3 Do people still use C?Ĭ exists everywhere in the modern world. It was mainly developed as a system programming language to write an operating system. C is the best option for system level programming language. This language is widely flexible to use memory management. The C programming language is so popular because it is known as the mother of all programming languages. The basic data types are also known as the primary data types in C programming. Types of Data Types in C Floating-point, integer, double, character. First, they used to call it as B language then later they made some improvement into it and renamed it as C and its superscript as C which was invented by Dr. It was developed by Dennis Ritchie and Ken Thompson at AT
