The following code example shows how to create a block expression. The block expression consists of two MethodCallExpression objects and one ConstantExpression object.


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

// The block expression allows for executing several expressions sequentually.
// When the block expression is executed,
// it returns the value of the last expression in the sequence.
BlockExpression blockExpr = Expression.Block(
    Expression.Call(
        null,
        typeof(Console).GetMethod("Write", new Type[] { typeof(String) }),
        Expression.Constant("Hello ")
       ),
    Expression.Call(
        null,
        typeof(Console).GetMethod("WriteLine", new Type[] { typeof(String) }),
        Expression.Constant("World!")
        ),
    Expression.Constant(42)
);

outputBlock.Text += "The result of executing the expression tree:" + "\n";
// The following statement first creates an expression tree,
// then compiles it, and then executes it.           
var result = Expression.Lambda<Func<int>>(blockExpr).Compile()();

// Print out the expressions from the block expression.
outputBlock.Text += "The expressions from the block expression:" + "\n";
foreach (var expr in blockExpr.Expressions)
   outputBlock.Text += expr.ToString() + "\n";

// Print out the result of the tree execution.
outputBlock.Text += "The return value of the block expression:" + "\n";
outputBlock.Text += result + "\n";

// This code example produces the following output:
//
// The result of executing the expression tree:
// Hello World!

// The expressions from the block expression:
// Write("Hello ")
// WriteLine("World!")
// 42

// The return value of the block expression:
// 42
