You can build an expression tree using Expression.AndAlso method which contains a conditional AND operation that evaluates the second operand only if the first operand evaluates to true. For example, you have the following code.
bool value = true && false;
Console.WriteLine(value);
Here is the code that is required to build the same functionality using expression tree.
Expression greaterThanExpr = Expression.AndAlso(
Expression.Constant(true),
Expression.Constant(false)
);
Console.WriteLine(Expression.Lambda<Func<bool>>(greaterThanExpr).Compile()());
