JsonReaderWriterFactory.CreateJsonReader Method (array<Byte[], Int32, Int32, XmlDictionaryReaderQuotas)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Creates an XmlDictionaryReader that can map a buffer encoded with JavaScript Object Notation (JSON), of a specified size and offset, to an XML Infoset.

Namespace:  System.Runtime.Serialization.Json
Assembly:  System.Runtime.Serialization.Json (in System.Runtime.Serialization.Json.dll)

Syntax

'Declaration
Public Shared Function CreateJsonReader ( _
    buffer As Byte(), _
    offset As Integer, _
    count As Integer, _
    quotas As XmlDictionaryReaderQuotas _
) As XmlDictionaryReader

public static XmlDictionaryReader CreateJsonReader(
    byte[] buffer,
    int offset,
    int count,
    XmlDictionaryReaderQuotas quotas
)

Parameters

  • buffer
    Type: array<System.Byte[]
    The input Byte buffer array from which to read.
  • offset
    Type: System.Int32
    Starting position from which to read in buffer.
  • count
    Type: System.Int32
    Number of bytes that can be read from buffer.

Return Value

Type: System.Xml.XmlDictionaryReader
An XmlDictionaryReader that can read JSON.

Exceptions

Exception Condition
ArgumentNullException

stream is nulla null reference (Nothing in Visual Basic).
ArgumentOutOfRangeException

offset is negative or exceeds the buffer length.
ArgumentOutOfRangeException

count is negative or exceeds the buffer length minus the offset.

Remarks

The character encoding (UTF-8, Unicode or Big-Endian Unicode) is auto-detected when the data is read.

Setting XmlDictionaryReaderQuotas to Max in Silverlight 5 applications effectively disables the use of quotas.
