예제

다음 코드 예제에서는 정수 변수에 값을 추가한 다음 작업 결과를 변수에 할당하는 식을 만드는 방법을 보여 줍니다.

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

// The Parameter expression is used to create a variable.
ParameterExpression variableExpr = Expression.Variable(typeof(int), "sampleVar");

// The block expression enables you to execute several expressions sequentually.
// In this bloc, the variable is first initialized with 1.
// Then the AddAssign method adds 2 to the variable and assigns the result to the variable.
BlockExpression addAssignExpr = Expression.Block(
    new ParameterExpression[] { variableExpr },
    Expression.Assign(variableExpr, Expression.Constant(1)),
    Expression.AddAssign(
        variableExpr,
        Expression.Constant(2)
    )
);

// Print out the expression from the block expression.
Console.WriteLine("The expressions from the block expression:");
foreach (var expr in addAssignExpr.Expressions)
    Console.WriteLine(expr.ToString());

Console.WriteLine("The result of executing the expression tree:");
// The following statement first creates an expression tree,
// then compiles it, and then executes it.
Console.WriteLine(Expression.Lambda<Func<int>>(addAssignExpr).Compile()());

// This code example produces the following output:
//
// The expressions from the block expression:
// (sampleVar = 1)
// (sampleVar += 2)
