[System.Windows.Markup.ContentProperty("Parameters")]
public sealed class InvokeMethod : System.Activities.AsyncCodeActivity

[<System.Windows.Markup.ContentProperty("Parameters")>]
type InvokeMethod = class

Examples

The following code sample demonstrates creating an InvokeMethod activity. This example is from the Using the InvokeMethod Activity sample.

new InvokeMethod
{
    TargetObject = new InArgument<TestClass>(ctx => testClass),
    MethodName = "InstanceMethod",
    Parameters =
    {
        new InArgument<string>("My favorite number is"),
        new InArgument<int>(42),
        new InArgument<string>("first item of the param array"),
        new InArgument<string>("second item of the param array"),
        new InArgument<string>("third item of the param array")
    }
},

Constructors

InvokeMethod()

Creates a new instance of the InvokeMethod class.

Properties

CacheId	Gets the identifier of the cache that is unique within the scope of the workflow definition. (Inherited from Activity)
Constraints	Gets a collection of Constraint activities that can be configured to provide validation for the Activity. (Inherited from Activity)
DisplayName	Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking. (Inherited from Activity)
GenericTypeArguments	The generic type arguments of the contained method.
Id	Gets an identifier that is unique in the scope of the workflow definition. (Inherited from Activity)
Implementation	Gets null or throws an error when there is an attempt to set the value of this property. (Inherited from AsyncCodeActivity)
ImplementationVersion	Gets or sets the implementation version of the activity. (Inherited from AsyncCodeActivity)
MethodName	The name of the method to be invoked when the activity executes.
Parameters	The parameter collection of the method to be invoked.
Result	The return value of the method operation.
RunAsynchronously	Gets or sets a value that indicates whether the activity's method is invoked asynchronously.
TargetObject	The object that contains the method to execute.
TargetType	The type of the TargetObject.

Methods

BeginExecute(AsyncCodeActivityContext, AsyncCallback, Object)	When implemented in a derived class and using the specified execution context, callback method, and user state, enqueues an asynchronous activity in a run-time workflow. (Inherited from AsyncCodeActivity)
CacheMetadata(ActivityMetadata)	Not implemented. Use CacheMetadata(CodeActivityMetadata) instead. (Inherited from AsyncCodeActivity)
CacheMetadata(CodeActivityMetadata)	Serves as a virtual method and converts information obtained by cache reflection into arguments for an asynchronous activity. (Inherited from AsyncCodeActivity)
Cancel(AsyncCodeActivityContext)	When implemented in a derived class and using the specified execution environment information, notifies the workflow runtime that the asynchronous activity operation has reached an early completion. Serves as a virtual method. (Inherited from AsyncCodeActivity)
EndExecute(AsyncCodeActivityContext, IAsyncResult)	When implemented in a derived class and using the specified execution environment information, notifies the workflow runtime that the associated asynchronous activity operation has completed. (Inherited from AsyncCodeActivity)
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)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
OnCreateDynamicUpdateMap(UpdateMapMetadata, Activity)	Raises an event when creating a map for the dynamic update. (Inherited from AsyncCodeActivity)
ShouldSerializeDisplayName()	Indicates whether the DisplayName property should be serialized. (Inherited from Activity)
ToString()	Returns a String that contains the Id and DisplayName of the Activity. (Inherited from Activity)
