Represents a constructor call.
Assemblies: System.Linq.Expressions (in System.Linq.Expressions.dll)
System.Core (in System.Core.dll)
Thetype exposes the following members.
|Arguments||Gets the arguments to the constructor.|
|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.)|
|Constructor||Gets the called constructor.|
|Members||Gets the members that can retrieve the values of the fields that were initialized with constructor arguments.|
|NodeType||Returns the node type of this Expression. (Overrides Expression.NodeType.)|
|Type||Gets the static type of the expression that this Expression represents. (Overrides Expression.Type.)|
|Accept||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||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|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||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||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 that represents the construction of a new instance of a dictionary object.
' Create a NewExpression that represents constructing ' a new instance of Dictionary(Of Integer, String). Dim newDictionaryExpression As System.Linq.Expressions.NewExpression = _ System.Linq.Expressions.Expression.[New]( _ Type.GetType("System.Collections.Generic.Dictionary`2[System.Int32, System.String]")) Console.WriteLine(newDictionaryExpression.ToString()) ' This code produces the following output: ' ' new Dictionary`2()
