以下是一个使用 System.Json 库将字符串转换为 JSON 对象的示例代码: delphi uses System.SysUtils, System.Json, System.Classes; procedure ConvertStringToJsonObject; var jsonString: string; jsonObject: TJSONObject; begin // 示例 JSON 字符串 jsonString := '{"name":"John", "age":30, "city":...
function StringToJSONString(const S: string; strict: Boolean = False): string; var I, J, L: Integer; P: PChar; C: Char; begin I := 1; J := 1; Result := ''; L := Length(S); P := PChar(S); while I <= L do begin C := Char(P^); Result := Result + Copy(S,...
function StringToJSONString(const S: string; strict: Boolean = False): string; var I, J, L: Integer; P: PChar; C: Char; begin I := 1; J := 1; Result := ''; L := Length(S); P := PChar(S); while I <= L do begin C := Char(P^); Result := Result + Copy(S,...
可以通过循环遍历的方式访问Json数组中的每个元素。 代码语言:txt 复制 var i: Integer; begin for i := 0 to JsonArray.Length - 1 do begin // 访问Json数组中的每个元素 ShowMessage(JsonArray.I[i].AsString); end; end; 在Delphi中解析Json数组的应用场景非常广泛,例如处理从后端接口返回的Json数据、...
json, item: TlkJSONbase; i: integer; list: TlkJSONObject; str: TlkJSONstring; begin json :=TlkJSON.ParseText(returnval); fori :=0topred(json.Count)do begin item :=TlkJSONObject(json).child[i]; //Thisisthe namedarray, nameinname, thearrayinObjvalue ...
例如：uses System.JSON; procedure ParseJSON(jsonStr: string); var jsonObj: TJSONObject; ...
{ function ToJsonString: string; class function FromJsonString(AJsonString: string): TDataClass; } end; TRootClass = class private FCode: Extended; FData: TArray<TDataClass>; FMsg: String; FMsgData: String; FPage: Extended; FTotal: Extended; ...
jsonObject.TryGetValue<string>('name', jsonValue) then ShowMessage('Name: ' + jsonValue.Value); // 解析整数属性 if jsonObject.TryGetValue<Integer>('age', jsonValue) then ShowMessage('Age: ' + IntToStr(jsonValue.Value)); // 解析嵌套的JSON对象 if jsonObject.TryGetValue<TJSONObject>(...
Delphi-JsonToDelphiClass Generates Delphi Classes based on JSON string. Just like XML Data Binding, but for JSON. Main features: Build entirely on the RTL (no external dependencies) so it's cross-platform; Accepts any valid JSON string, no matter how complex the object is; ...
Attempts to convert a string to JSON when the string starts with { or [ TDataSetSerializeConfig.GetInstance.Export.TryConvertStringToJson := True; Export only fields visible TDataSetSerializeConfig.GetInstance.Export.ExportOnlyFieldsVisible := True; ...
