Remarks

Note

This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

ActivityBind allows data to flow from one activity to another activity within a workflow. ActivityBind is a declarative way of doing what otherwise must be accomplished using code, and therefore is a key element of most workflows that are written entirely in XAML markup.

ActivityBind represents a bind expression that has an Activity member as a target. The target activity member can be a property, an event, or a field. An Activity property or method can use ActivityBind to bind to another Activity member.

For example, if activity1 has property1 set to some value and if activity2 has its property1 set to ActivityBind with Name="activity1" and Path="property1", at run time the activity2.property1 gets its value from activity1.property1.

Constructors

ActivityBind()	Initializes a new instance of the ActivityBind class.
ActivityBind(String, String)	Initializes a new instance of the ActivityBind class with `name` and `path` parameters.
ActivityBind(String)	Initializes a new instance of the ActivityBind class with the `name` parameter.

Properties

Name	Gets or sets the name of the Activity that the ActivityBind points to.
Path	Gets or sets the path for a member of the target activity. The value can use dotted notation to indicate a path to a nested value. For example, a path of "A.B.C" indicates that the ActivityBind is to a field or property named 'C', which is a member of the field or property 'B', which in turn is a field or property 'A', which is a member of the target activity.
UserData	Gets an IDictionary of user data relating to this instance.

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetRuntimeValue(Activity, Type)	Gets the Object representing the run-time value of this ActivityBind.
GetRuntimeValue(Activity)	Gets the Object representing the run-time value of this ActivityBind.
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ProvideValue(IServiceProvider)	Returns the current instance of this class.
SetRuntimeValue(Activity, Object)	Sets the run-time value.
ToString()	Calculates and returns a combination of the Name and Path property strings.
