JavaScriptSerializer.MaxJsonLength Property


Gets or sets the maximum length of JSON strings that are accepted by the JavaScriptSerializer class.

 property int MaxJsonLength { int get(); void set(int value); };
public int MaxJsonLength { get; set; }
member this.MaxJsonLength : int with get, set
Public Property MaxJsonLength As Integer

Property Value

The maximum length of JSON strings. The default is 2097152 characters, which is equivalent to 4 MB of Unicode string data.


The property is set to a value that is less than one.


The value of the MaxJsonLength property applies only when you explicitly create an instance of the JavaScriptSerializer class. Use the jsonSerialization element of the configuration file to set the maximum length for the internal serializer instance that is used by the asynchronous communication layer. For more information about the configuration elements for serialization, see How to: Configure ASP.NET Services in Microsoft Ajax.
