Expression Tree Tutorial Not

You can build an expression tree which contains a bitwise complement operation using Expression.Not method. For example, you have the following code.

bool value = false;
Console.WriteLine(!value);

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

Expression greaterThanExpr = Expression.Not(
    Expression.Constant(false));

Console.WriteLine(Expression.Lambda<Func<bool>>(greaterThanExpr).Compile()());
