ApplicationId Class

 

Contains information used to uniquely identify a manifest-based application. This class cannot be inherited.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

System.Object

<SerializableAttribute>
<ComVisibleAttribute(True)>
Public NotInheritable Class ApplicationId

NameDescription
System_CAPS_pubmethodApplicationId(Byte(), String, Version, String, String)

Initializes a new instance of the ApplicationId class.

NameDescription
System_CAPS_pubpropertyCulture

Gets a string representing the culture information for the application.

System_CAPS_pubpropertyName

Gets the name of the application.

System_CAPS_pubpropertyProcessorArchitecture

Gets the target processor architecture for the application.

System_CAPS_pubpropertyPublicKeyToken

Gets the public key token for the application.

System_CAPS_pubpropertyVersion

Gets the version of the application.

NameDescription
System_CAPS_pubmethodCopy()

Creates and returns an identical copy of the current application identity.

System_CAPS_pubmethodEquals(Object)

Determines whether the specified ApplicationId object is equivalent to the current ApplicationId.(Overrides Object.Equals(Object).)

System_CAPS_pubmethodGetHashCode()

Gets the hash code for the current application identity.(Overrides Object.GetHashCode().)

System_CAPS_pubmethodGetType()

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

System_CAPS_pubmethodToString()

Creates and returns a string representation of the application identity.(Overrides Object.ToString().)

An application identity consists of the publisher's public key, the application name, the target processor architecture, the application culture, and the application version. The application identity properties values correspond to information contained in the application manifest. For more information about the application manifest, see ClickOnce Application Manifest.

ApplicationId is used by the ApplicationSecurityInfo class to identify a manifest-based application.

The following code example displays the ApplicationId properties by obtaining the ApplicationId from an ApplicationSecurityInfo instance created using the ActivationContext for the currently executing manifest-based application.
