IndexExpression Class
Represents indexing a property or array.
Assembly: System.Core (in System.Core.dll)
| Name | Description | |
|---|---|---|
![]() | Arguments | Gets the arguments that will be used to index the property or array. |
![]() | 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.) |
![]() | Indexer | Gets the PropertyInfo for the property if the expression represents an indexed property, returns null otherwise. |
![]() | NodeType | Returns the node type of this Expression.(Overrides Expression::NodeType.) |
![]() | Object | An object to index. |
![]() | 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. |
The following code example shows how to create an object of the IndexExpression type and use it to change a value of an array element by using the ArrayAccess method.
