ConditionalExpression Class
Represents an expression that has a conditional operator.
Assembly: System.Core (in System.Core.dll)
| Name | Description | |
|---|---|---|
 | 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.) |
| IfFalse | Gets the expression to execute if the test evaluates to false. |
| IfTrue | Gets the expression to execute if the test evaluates to true. |
| NodeType | Returns the node type of this expression. Extension nodes should return Extension when overriding this method.(Overrides Expression::NodeType.) |
| Test | Gets the test of the conditional operation. |
| 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.(Overrides Expression::Accept(ExpressionVisitor^).) |
 | 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 the default hash function. (Inherited from Object.) |
| GetType() | |
| MemberwiseClone() | |
| 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^, Expression^, 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.) |
Use the Condition factory method to create a ConditionalExpression.
The NodeType of a ConditionalExpression is Conditional.
The following code example shows how to create an expression that represents a conditional statement. If the first argument evaluates to true, the second argument is executed; otherwise, the third argument is executed.
