CodeDelegateInvokeExpression Class
Represents an expression that raises an event.
System.CodeDom.CodeObject
System.CodeDom.CodeExpression
System.CodeDom.CodeDelegateInvokeExpression
Assembly: System (in System.dll)
The CodeDelegateInvokeExpression type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | CodeDelegateInvokeExpression() | Initializes a new instance of the CodeDelegateInvokeExpression class. |
![]() | CodeDelegateInvokeExpression(CodeExpression) | Initializes a new instance of the CodeDelegateInvokeExpression class using the specified target object. |
![]() | CodeDelegateInvokeExpression(CodeExpression, CodeExpression[]) | Initializes a new instance of the CodeDelegateInvokeExpression class using the specified target object and parameters. |
| Name | Description | |
|---|---|---|
![]() | Parameters | Gets or sets the parameters to pass to the event handling methods attached to the event. |
![]() | TargetObject | Gets or sets the event to invoke. |
![]() | UserData | Gets the user-definable data for the current object. (Inherited from CodeObject.) |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (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.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
CodeDelegateInvokeExpression can be used to represent code that invokes an event. Invoking an event invokes all delegates that are registered with the event using the specified parameters.
The TargetObject property specifies the event to invoke. The Parameters property specifies the parameters to pass to the delegates for the event.
The following example demonstrates use of a CodeDelegateInvokeExpression to invoke an event named TestEvent.
// Invokes the delegates for an event named TestEvent, passing a local object reference and a new System.EventArgs. CodeDelegateInvokeExpression invoke1 = new CodeDelegateInvokeExpression( new CodeEventReferenceExpression(new CodeThisReferenceExpression(), "TestEvent"), new CodeExpression[] { new CodeThisReferenceExpression(), new CodeObjectCreateExpression("System.EventArgs") } ); // A C# code generator produces the following source code for the preceeding example code: // this.TestEvent(this, new System.EventArgs());
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
