DynamicExpression Class

DynamicExpression Class

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Represents a dynamic operation.

System::Object
  System.Linq.Expressions::Expression
    System.Linq.Expressions::DynamicExpression

Namespace:  System.Linq.Expressions
Assembly:  System.Core (in System.Core.dll)

No code example is currently available or this language may not be supported.

The DynamicExpression type exposes the following members.

  NameDescription
Public propertyArgumentsGets the arguments to the dynamic operation.
Public propertyBinderGets the CallSiteBinder, which determines the run-time behavior of the dynamic site.
Public propertyCanReduceIndicates 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.)
Public propertyDelegateTypeGets the type of the delegate used by the CallSite.
Public propertyNodeTypeReturns the node type of this expression. Extension nodes should return Extension when overriding this method. (Overrides Expression::NodeType.)
Public propertyTypeGets the static type of the expression that this Expression represents. (Overrides Expression::Type.)

  NameDescription
Protected methodAcceptDispatches to the specific visit method for this node type. For example, MethodCallExpression calls the VisitMethodCall. (Overrides Expression::Accept(ExpressionVisitor).)
Public methodStatic memberDynamic(CallSiteBinder, Type, IEnumerable<Expression>)Creates a DynamicExpression that represents a dynamic operation bound by the provided CallSiteBinder.
Public methodStatic memberDynamic(CallSiteBinder, Type, Expression)Creates a DynamicExpression that represents a dynamic operation bound by the provided CallSiteBinder.
Public methodStatic memberDynamic(CallSiteBinder, Type, array<Expression>)Creates a DynamicExpression that represents a dynamic operation bound by the provided CallSiteBinder.
Public methodStatic memberDynamic(CallSiteBinder, Type, Expression, Expression)Creates a DynamicExpression that represents a dynamic operation bound by the provided CallSiteBinder.
Public methodStatic memberDynamic(CallSiteBinder, Type, Expression, Expression, Expression)Creates a DynamicExpression that represents a dynamic operation bound by the provided CallSiteBinder.
Public methodStatic memberDynamic(CallSiteBinder, Type, Expression, Expression, Expression, Expression)Creates a DynamicExpression that represents a dynamic operation bound by the provided CallSiteBinder.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodStatic memberMakeDynamic(Type, CallSiteBinder, IEnumerable<Expression>)Creates a DynamicExpression that represents a dynamic operation bound by the provided CallSiteBinder.
Public methodStatic memberMakeDynamic(Type, CallSiteBinder, Expression)Creates a DynamicExpression that represents a dynamic operation bound by the provided CallSiteBinder and one argument.
Public methodStatic memberMakeDynamic(Type, CallSiteBinder, array<Expression>)Creates a DynamicExpression that represents a dynamic operation bound by the provided CallSiteBinder.
Public methodStatic memberMakeDynamic(Type, CallSiteBinder, Expression, Expression)Creates a DynamicExpression that represents a dynamic operation bound by the provided CallSiteBinder and two arguments.
Public methodStatic memberMakeDynamic(Type, CallSiteBinder, Expression, Expression, Expression)Creates a DynamicExpression that represents a dynamic operation bound by the provided CallSiteBinder and three arguments.
Public methodStatic memberMakeDynamic(Type, CallSiteBinder, Expression, Expression, Expression, Expression)Creates a DynamicExpression that represents a dynamic operation bound by the provided CallSiteBinder and four arguments.
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodReduceReduces 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.)
Public methodReduceAndCheckReduces 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.)
Public methodReduceExtensionsReduces 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.)
Public methodToStringReturns a textual representation of the Expression. (Inherited from Expression.)
Public methodUpdateCompares the value sent to the parameter, arguments, to the Arguments property of the current instance of DynamicExpression. If the values of the parameter and the property are equal, the current instance is returned. If they are not equal, a new DynamicExpression instance is returned that is identical to the current instance except that the Arguments property is set to the value of parameter arguments.
Protected methodVisitChildrenReduces 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.)

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
