LambdaExpression Class
Describes a lambda expression. This captures a block of code that is similar to a .NET method body.
Assembly: System.Core (in System.Core.dll)
System.Linq.Expressions.Expression
System.Linq.Expressions.LambdaExpression
System.Linq.Expressions.Expression<'TDelegate>
| Name | Description | |
|---|---|---|
![]() | Body | Gets the body of the lambda expression. |
![]() | 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.) |
![]() | Name | Gets the name of the lambda expression. |
![]() | NodeType | Returns the node type of this Expression.(Overrides Expression.NodeType.) |
![]() | Parameters | Gets the parameters of the lambda expression. |
![]() | ReturnType | Gets the return type of the lambda expression. |
![]() | TailCall | Gets the value that indicates if the lambda expression will be compiled with the tail call optimization. |
![]() | Type | Gets the static type of the expression that this Expression represents.(Overrides Expression.Type.) |
| Name | Description | |
|---|---|---|
![]() | Accept(ExpressionVisitor) | Dispatches to the specific visit method for this node type. For example, MethodCallExpression calls the VisitMethodCall.(Inherited from Expression.) |
![]() | Compile() | Produces a delegate that represents the lambda expression. |
![]() | Compile(DebugInfoGenerator) | Produces a delegate that represents the lambda expression. |
![]() | CompileToMethod(MethodBuilder) | Compiles the lambda into a method definition. |
![]() | CompileToMethod(MethodBuilder, DebugInfoGenerator) | Compiles the lambda into a method definition and custom debug information. |
![]() | 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.) |
![]() | 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 LambdaExpression type represents a lambda expression in the form of an expression tree. The Expression<'TDelegate> type, which derives from LambdaExpression and captures the type of the lambda expression more explicitly, can also be used to represent a lambda expression. At runtime, an expression tree node that represents a lambda expression is always of type Expression<'TDelegate>.
The value of the NodeType property of a LambdaExpression is Lambda.
Use the Lambda factory methods to create a LambdaExpression object.
