Evaluate expression at run-time?

Hi all,

Is it possible to have an uncompiled C# expression evaluated at runtime?
I'd like to store an expression within an XML file then evaluate it when the
time comes, something like:

MyExpression = "DateTime.Today.Month % 2) = 0?"Even\":\"Odd\"";

string strResultString = MyExpression.Evaluate();

where MyExpression.Evaluate() represents a method that would evaluate the
text as a command, returning "Odd" (this month) to the strResultString.

Is something like this possible?
