You can build an expression tree which contains an arithmetic subtraction operation using
Expression.Subtract method. For example, you have the following code.
int value = 33 - 6; Console.WriteLine(value);
Here is the code that is required to build the same functionality using expression tree.
Expression valueExpr = Expression.Subtract( Expression.Constant(33), Expression.Constant(6) ); Console.WriteLine(Expression.Lambda<Func<int>>(valueExpr).Compile()());
