Expression Tree Tutorial Multiplication Expression

You can build an expression tree which contains an arithmetic multiplication operation using Expression.Multiply method. For example, you have the following code.

int value = 30 * 5;
Console.WriteLine(value);

Here is the code that is required to build the same functionality using expression tree.

Expression valueExpr = Expression.Multiply(
    Expression.Constant(30),
    Expression.Constant(5)
);

Console.WriteLine(Expression.Lambda<Func<int>>(valueExpr).Compile()());
