No, i cant change the code json.
it is necessary manipulate the variable resposta to acept the Escape sequence not recognized
I tried other code but not work, it generate another exception. The code is:
Dim resposta As String ="{"SUCCESS":0,"IDERRO":1,"ERRO":"O CAMPO NOME \U00E9 OBRIGAT\U00F3RIO"}"
Dim stream = New MemoryStream(Encoding.UTF8.GetBytes(resposta.ToString()))
Dim obj As Object = New JavaScriptSerializer().Deserialize(Of MensagemErro)(stream.toString())
The exeption is System.ArgumentException: 'Invalid JSON primitive: System.IO.MemoryStream.'
Thank you

The Dim statements you are posting are lines of code in your program. Why is it that you cannot change them? If you change each \ to \ in your first message, the error should disappear.
No, i can't change or manupulate the json.
Hi CsarOliveira, do you mean that you can't modify the resposta in vb file? As BarrySchwarz suggests, you could modify the code like
Dim resposta As String ="{"SUCCESS":0,"IDERRO":1,"ERRO":"O CAMPO NOME \\U00E9 OBRIGAT\\U00F3RIO"}"
and then pass it into Deserialize() method.
Hi @César Oliveira ,
You could use Chrw() function to recognize escape sequence in visual basic, which is like:
"O CAMPO NOME \U00E9 OBRIGAT\U00F3RIO" -> "O CAMPO NOME" + ChrW(&HE9) + " OBRIGAT" + ChrW(&HF3) + "RIO"
Best Regards,
Dylan
Not is possíble.
This json came of WebService
I can't change the json
How i solve the problema in vb.net ?
Thank you
@César Oliveira - your JSON string, resposta has an escape sequence that VS does not recognize. The "\U" within the JSON string is not supported. You should change the \U to \U.
