Using JSON StringOf with Non-String Members

See more JSON Examples

If a JSON member is a boolean, integer, or null, using StringOf will return its string representation. Unicode C++

#include <CkJsonObjectW.h>

void ChilkatSample(void)
    {
    //  Create JSON with members of different data types.
    CkJsonObjectW json;

    json.UpdateInt(L"a",123);
    json.UpdateBool(L"b",true);
    json.UpdateNull(L"c");

    json.put_EmitCompact(false);
    wprintf(L"%s\n",json.emit());

    //  Resulting JSON:
    //  {
    //    "a": 123,
    //    "b": true,
    //    "c": null
    //  }

    const wchar_t *a = json.stringOf(L"a");
    wprintf(L"%s\n",a);

    const wchar_t *b = json.stringOf(L"b");
    wprintf(L"%s\n",b);

    const wchar_t *c = json.stringOf(L"c");
    wprintf(L"%s\n",c);

    //  Output

    //  123
    //  true
    //  null

    //  If you want to get the integer, boolean, or null value
    //  you need to use the methods matching the data type
    int ival = json.IntOf(L"a");
    bool bval = json.BoolOf(L"b");
    bool hasNull = json.IsNullOf(L"c");
    }
