Exempel

I följande kodexempel visas hur du skapar ett uttryck som lägger till två heltal.

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

// This expression adds the values of its two arguments.
// Both arguments must be of the same type.
Expression sumExpr = Expression.Add(
    Expression.Constant(1),
    Expression.Constant(2)
);

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

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

// This code example produces the following output:
//
// (1 + 2)
// 3

' Add the following directive to your file:
' Imports System.Linq.Expressions  

' This expression adds the values of its two arguments.
' Both arguments must be of the same type.
Dim sumExpr As Expression = Expression.Add(
    Expression.Constant(1),
    Expression.Constant(2)
    )

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

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

' This code example produces the following output:
