InvocationExpression Class
Represents an expression that applies a delegate or lambda expression to a list of argument expressions.
Assembly: System.Core (in System.Core.dll)
| Name | Description | |
|---|---|---|
![]() | Arguments | Gets the arguments that the delegate or lambda expression is applied to. |
![]() | CanReduce | Indicates that the node can be reduced to a simpler node. If this returns true, Reduce() can be called to produce the reduced form.(Inherited from Expression.) |
![]() | Expression | Gets the delegate or lambda expression to be applied. |
![]() | NodeType | Returns the node type of this expression. Extension nodes should return Extension when overriding this method.(Overrides Expression::NodeType.) |
![]() | Type | Gets the static type of the expression that this Expression represents.(Overrides Expression::Type.) |
| Name | Description | |
|---|---|---|
![]() | Accept(ExpressionVisitor^) | Dispatches to the specific visit method for this node type. For example, MethodCallExpression calls the VisitMethodCall.(Inherited from Expression.) |
![]() | 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() | |
![]() | Reduce() | Reduces this node to a simpler expression. If CanReduce returns true, this should return a valid expression. This method can return another node which itself must be reduced.(Inherited from Expression.) |
![]() | ReduceAndCheck() | Reduces this node to a simpler expression. If CanReduce returns true, this should return a valid expression. This method can return another node which itself must be reduced.(Inherited from Expression.) |
![]() | ReduceExtensions() | Reduces the expression to a known node type (that is not an Extension node) or just returns the expression if it is already a known type.(Inherited from Expression.) |
![]() | ToString() | Returns a textual representation of the Expression.(Inherited from Expression.) |
![]() | Update(Expression^, IEnumerable<Expression^>^) | Creates a new expression that is like this one, but using the supplied children. If all of the children are the same, it will return this expression. |
![]() | VisitChildren(ExpressionVisitor^) | Reduces the node and then calls the visitor delegate on the reduced expression. The method throws an exception if the node is not reducible.(Inherited from Expression.) |
| Name | Description | |
|---|---|---|
![]() ![]() | IArgumentProvider::GetArgument(Int32) | Returns the argument at index, throwing if index is out of bounds. You should not use this member. It is only public due to assembly refactoring, and it is used internally for performance optimizations. |
![]() ![]() | IArgumentProvider::ArgumentCount | Returns the number of arguments to the expression tree node. You should not use this member. It is only public due to assembly refactoring, and it is used internally for performance optimizations. |
