Specifies that JavaScriptSerializer will not serialize the public property or public field. This class cannot be inherited.

public ref class ScriptIgnoreAttribute sealed : Attribute

Examples

The following example demonstrates how to apply ScriptIgnoreAttribute to the Comment field in the custom class named Group. This instructs JavaScriptSerializer to ignore the field when serializing an instance of the class to JSON format.

using System;
using System.Web.Script.Serialization;

public class Group
{
    // The JavaScriptSerializer ignores this field.
    [ScriptIgnore]
    public string Comment;

    // The JavaScriptSerializer serializes this field.
    public string GroupName;
}

Imports System.Web.Script.Serialization

Public Class Group
    ' The JavaScriptSerializer ignores this field.
    <ScriptIgnore()> Public Comment As String

    ' The JavaScriptSerializer serializes this field.
    Public GroupName As String
End Class

Remarks

If you apply ScriptIgnoreAttribute to a public property or public field of a class, then JavaScriptSerializer ignores, or skips, the member when serializing an instance of the class to JavaScript Object Notation (JSON) format.

The ScriptIgnoreAttribute will have no effect if the ResponseFormat property is set to Xml. If you want to have the same behavior when serializing to XML format, XmlIgnoreAttribute should be applied to the property or field instead. This is because the class will be serialized by using XmlSerializer instead of JavaScriptSerializer.

You can also apply both ScriptIgnoreAttribute and XmlIgnoreAttribute to a property or field. In this case, the property or field will be ignored for JSON and XML response formats.

Constructors

ScriptIgnoreAttribute()

Initializes a new instance of the ScriptIgnoreAttribute class.

Properties

ApplyToOverrides	Gets or set whether to override the ScriptIgnoreAttribute so that the JavaScriptSerializer will consider the serialization of the public property or public field.
TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)

Methods

Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute)
GetHashCode()	Returns the hash code for this instance. (Inherited from Attribute)
GetType()	Gets the Type of the current instance. (Inherited from Object)
IsDefaultAttribute()	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute)
Match(Object)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)

Explicit Interface Implementations

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)	Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute)
_Attribute.GetTypeInfoCount(UInt32)	Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)	Provides access to properties and methods exposed by an object. (Inherited from Attribute)
