次のコード例では、インクリメント演算を表す式を作成する方法を示します。The following code example shows how to create an expression that represents an increment operation.

// Add the following directive to your file:
// using System.Linq.Expressions;  

// This expression represents an increment operation. 
double num = 5.5;
Expression incrementExpr = Expression.Increment(
                            Expression.Constant(num)
                        );


// Print out the expression.
Console.WriteLine(incrementExpr.ToString());

// The following statement first creates an expression tree,
// then compiles it, and then executes it.
Console.WriteLine(Expression.Lambda<Func<double>>(incrementExpr).Compile()());

// The value of the variable did not change,
// because the expression is functional.
Console.WriteLine("object: " + num);

// This code example produces the following output:
//
// Increment(5.5)
// 6.5
// object: 5.5
'Add the following directive to your file:
' Imports System.Linq.Expressions   
Dim num As Double = 5.5
' This expression represents an increment operation. 
Dim incrementExpr As Expression = Expression.Increment(
                            Expression.Constant(num)
                        )

' Print the expression.
Console.WriteLine(incrementExpr.ToString())

' The following statement first creates an expression tree,
' then compiles it, and then executes it.
Console.WriteLine(Expression.Lambda(Of Func(Of Double))(incrementExpr).Compile()())

' The value of the variable did not change,
' because the expression is functional.
Console.WriteLine("object: " & num)

' This code example produces the following output:
'
' Increment(5.5)
' 6.5
' object: 5.5

注釈

この式は、機能に渡されるオブジェクトの値を変更することはできません。This expression is functional and does not change the value of the object that is passed to it.
