Examples

The following example shows how to apply GenerateScriptTypeAttribute to a Web service class and to a Web method. As a result, the ColorObject type and its nested type FavoriteColors are included in the proxy object.

Remarks

In AJAX-enabled ASP.NET Web sites, ASP.NET can automatically generate proxy objects for methods of a Web service class. It does this for most top-level types for the input parameters and return values of any Web methods that are marked with ScriptServiceAttribute.

In other cases, if you proxy objects generated for server types, you must apply GenerateScriptTypeAttribute manually. You can apply GenerateScriptTypeAttribute to the Web service itself or to any Web service method or static page method marked with WebMethodAttribute.

In some cases, even if the type corresponds to an input parameter or return value of a Web service method, the proxy will not be generated automatically. In that case, you must use the GenerateScriptTypeAttribute attribute to generate the proxy object for the type. This occurs for generic types and arrays that have more than one argument, such as Dictionary<string,<T>>.

One or more instances of GenerateScriptTypeAttribute can be applied to a Web service class or method. ASP.NET will then generate an ECMAScript (JavaScript) proxy class for each top-level type that is referenced by each declaration of GenerateScriptTypeAttribute.

Note

If you want to generate proxy objects for nested types, you must manually apply GenerateScriptTypeAttribute to each nested type. ASP.NET generates proxies only for top-level types and does not automatically recursively apply the attribute to nested types.

Constructors

GenerateScriptTypeAttribute(Type)

Initializes a new instance of the GenerateScriptTypeAttribute class for the specified type.

Properties

ScriptTypeId	Gets or sets the type identifier for the type metadata marker.
Type	Gets the type that is included in the proxy object.
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)
