ScriptServiceAttribute Class

ScriptServiceAttribute Class


Indicates that a Web service can be invoked from script. This class cannot be inherited.

Namespace:   System.Web.Script.Services
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)


[<AttributeUsageAttribute(AttributeTargets.Class | AttributeTargets.Interface)>]
type ScriptServiceAttribute = 
        inherit Attribute


Initializes a new instance of the ScriptServiceAttribute class.


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)


This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)


Returns the hash code for this instance.(Inherited from Attribute.)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_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.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

To invoke a Web service method from ECMAScript (JavaScript), you must apply the ScriptServiceAttribute attribute to the related Web service class. When you apply ScriptServiceAttribute to a Web service class definition that contains one or more methods with WebMethodAttribute applied, the proxy generation script creates a proxy object that corresponds to the Web service class.

For more information about using attributes, see Extending Metadata Using Attributes.

The following example demonstrates how to apply ScriptServiceAttribute to the Web service class definition so that its methods can be called from client script.
