Expression(TDelegate).Compile Method

Compiles the lambda expression described by the expression tree into executable code and produces a delegate that represents the lambda expression.

Namespace:  System.Linq.Expressions
Assembly:  System.Core (in System.Core.dll)
member Compile : unit -> 'TDelegate 

Return Value

Type: TDelegate
A delegate of type TDelegate that represents the compiled lambda expression described by the Expression(TDelegate).

The Compile method produces a delegate of type TDelegate at runtime. When that delegate is executed, it has the behavior described by the semantics of the Expression(TDelegate).

The Compile method can be used to obtain the value of any expression tree. First, create a lambda expression that has the expression as its body by using the Lambda method. Then call Compile to obtain a delegate, and execute the delegate to obtain the value of the expression.

The following code example demonstrates how Compile is used to execute an expression tree.
