TypeBinaryExpression Class
Represents an operation between an expression and a type.
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.) |
![]() | Expression | Gets the expression operand of a type test operation. |
![]() | 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.) |
![]() | TypeOperand | Gets the type operand of a type test operation. |
| 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) | 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.) |
The following example creates a TypeBinaryExpression object that represents a type test of a string value against the Int32 type.
' Create a TypeBinaryExpression that represents a ' type test of the String "spruce" against the Int32 type. Dim typeBinaryExpression As System.Linq.Expressions.TypeBinaryExpression = _ System.Linq.Expressions.Expression.TypeIs( _ System.Linq.Expressions.Expression.Constant("spruce"), _ Type.GetType("System.Int32")) Console.WriteLine(typeBinaryExpression.ToString()) ' This code produces the following output: ' ' ("spruce" Is Int32)
