在Delphi中,JSON解析通常涉及到将JSON字符串转换为Delphi对象或数据结构,以便程序能够处理这些数据。 2. 研究Delphi中可用的JSON解析库或组件 在Delphi中,有多个库可以用于JSON解析,包括但不限于: SuperObject:一个功能强大的JSON解析库,支持JSON的生成和解析。 JSON Data Objects (JDO):另一个JSON解析库,提供了丰富...
JSON arrays are a bit more involved that the other simple classes. When calling the constructor of a TJSONArray you can pass no parameters, a single TJSONValue, two TJSONValues, or two strings. If you pass one or more arguments, those passed objects will appear as the first objects in ...

StringList使用 在Delphi中,如果程序需要动态创建大量的对象,那么我们可以利用StringList对象来管理这些动态生成的对象。...具体步骤如下: --- 1、创建StringList对象: OBJ := TStringList.Create; 2、保存动态生成的对象: OBJ.AddObject('标识','对象名'); 3、调用生成的对象...OBJ.Objects[序号/OBJ.Ind...
New! Added MAX_REQUEST_SIZE for limiting the size of the incoming HTTP requests. IDE Expert is updated too! New! Added method TMVCJsonDataObjectsSerializer.ListToJsonArray New! TMVCResponse for handle generic (non error) response New! TMVCErrorResponse for handle generic error response New!
4、释放动态生成的对象:(OBJ.Objects[序号/OBJ.IndexOf('标识')] as 对象类型).Free; 对象类型(OBJ.Objects[序号/OBJ.IndexOf('标识')]).Free; 释放对象后记得要删除StringList里对应的记录: OBJ.Delete(序号/OBJ.IndexOf('标识')); 5、StringList的释放:if Assigned(OBJ) then OBJ.Free; ...
All installation features and options are on a single screen, with the languages (Delphi or C++) and target platforms (Windows, iOS, etc.) options as the central part of the screen. The additional items are shown in a list on the right sidebar. ...
