(.NET Core C#) JSON: Access Array ValuesDemonstrates how to access values in a JSON array.
Chilkat.JsonObject json = new Chilkat.JsonObject(); string jsonStr = "{ \"id\": 1, \"name\": \"A green door\", \"tags\": [\"home\", 22, \"green\"], \"price\": 125 }"; bool success = json.Load(jsonStr); if (success != true) { Debug.WriteLine(json.LastErrorText); return; } // Get the "tags" array, which contains "home", 22, "green" Chilkat.JsonArray tagsArray = json.ArrayOf("tags"); if (json.LastMethodSuccess == false) { Debug.WriteLine("tags member not found."); return; } // Get the value at each array index. // Output will be: // [0] = home // [0] as integer = 0 // [1] = 22 // [1] as integer = 22 // [2] = green // [2] as integer = 0 int arraySize = tagsArray.Size; int i; for (i = 0; i <= arraySize - 1; i++) { string sValue = tagsArray.StringAt(i); Debug.WriteLine("[" + Convert.ToString(i) + "] = " + sValue); int iValue = tagsArray.IntAt(i); Debug.WriteLine("[" + Convert.ToString(i) + "] as integer = " + Convert.ToString(iValue)); } // Note: The StringAt method returns the value as a string regardless of the type. // The IntAt method returns the value as an integer. If the value does not convert to // an integer, then 0 is returned |
