Constructors

ProjectionBindingExpression(Expression, IDictionary<IProperty,Int32>)	Creates a new instance of the ProjectionBindingExpression class.
ProjectionBindingExpression(Expression, Int32, Type)	Creates a new instance of the ProjectionBindingExpression class.
ProjectionBindingExpression(Expression, IReadOnlyDictionary<IProperty,Int32>)	Obsolete. Creates a new instance of the ProjectionBindingExpression class.
ProjectionBindingExpression(Expression, ProjectionMember, Type)	Creates a new instance of the ProjectionBindingExpression class.

Properties

Index	The projection member to bind if binding is via projection index.
IndexMap	Obsolete. The projection member to bind if binding is via index map for a value buffer.
NodeType	Gets the node type of this Expression.
ProjectionMember	The projection member to bind if binding is via projection member.
QueryExpression	The query expression to bind with.
Type	Gets the static type of the expression that this Expression represents.

Methods

Equals(Object)	System.Linq.Expressions.Expression.Equals(System.Object)
GetHashCode()	System.Linq.Expressions.Expression.GetHashCode
Print(ExpressionPrinter)
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.
