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. PowerBuilder

integer li_rc
oleobject loo_Json
string a
string b
string c
long li_Ival
long li_Bval
long li_HasNull

//  Create JSON with members of different data types.
loo_Json = create oleobject
li_rc = loo_Json.ConnectToNewObject("Chilkat.JsonObject")
if li_rc < 0 then
    destroy loo_Json
    MessageBox("Error","Connecting to COM object failed")
    return
end if

loo_Json.UpdateInt("a",123)
loo_Json.UpdateBool("b",1)
loo_Json.UpdateNull("c")

loo_Json.EmitCompact = 0
Write-Debug loo_Json.Emit()

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

a = loo_Json.StringOf("a")
Write-Debug a

b = loo_Json.StringOf("b")
Write-Debug b

c = loo_Json.StringOf("c")
Write-Debug 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
