MemberExpression Class
Represents accessing a field or property.
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 containing object of the field or property. |
![]() | Member | Gets the field or property to be accessed. |
![]() | NodeType | Returns the node type of this Expression.(Overrides Expression.NodeType.) |
![]() | Type | Gets the static type of the expression that this Expression represents.(Inherited from Expression.) |
| 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) | 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 Field, Property or PropertyOrField factory methods to create a MemberExpression.
The value of the NodeType property of a MemberExpression is MemberAccess.
The following example creates a MemberExpression that represents getting the value of a field member.
class Animal { public string species; } public static void CreateFieldExpression() { Animal horse = new Animal(); // Create a MemberExpression that represents getting // the value of the 'species' field of class 'Animal'. System.Linq.Expressions.MemberExpression memberExpression = System.Linq.Expressions.Expression.Field( System.Linq.Expressions.Expression.Constant(horse), "species"); Console.WriteLine(memberExpression.ToString()); // This code produces the following output: // // value(CodeSnippets.FieldExample+Animal).species }
