Method Attribute Class
Specifies which HTTP verb is used to invoke a method, and the format of the response. This class cannot be inherited.
public ref class ScriptMethodAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Method)] public sealed class ScriptMethodAttribute : Attribute
type ScriptMethodAttribute = class inherit Attribute
Public NotInheritable Class ScriptMethodAttribute Inherits Attribute
The following example shows how to apply ScriptMethodAttribute to the
EchoStringAndDate methods to specify which HTTP verb to use and to specify the response format.
The ScriptMethodAttribute attribute is optional. (However, methods that can be called from client script must have the System.Web.Services.WebMethodAttribute attribute applied.). If a method is not marked with ScriptMethodAttribute, the method will be called by using the HTTP POST command and the response will be serialized as JSON. You cannot override this setting from script.
Specifies whether the method will be invoked by using the HTTP GET command. The default is
Setting the UseHttpGet property to
truemight pose a security risk for your application if you are working with sensitive data or transactions. In GET requests, the message is encoded by the browser into the URL and is therefore an easier target for tampering. For both GET and POST requests, you should follow security guidelines to protect sensitive data.
Specifies whether the response will be serialized as JSON or as XML. The default is
Json. The ResponseFormat property is useful to specify XML as the return type when the method returns an XmlDocument or an XmlElement object.
Specifies whether all return types, including string types, are serialized as XML. The value of the XmlSerializeString property is ignored when the response is serialized as JSON.
