You can build an expression tree which contains an arithmetic addition operation using
Expression.Add method. For example, you have the following code.
int sum = 3 + 6; Console.WriteLine(sum);
Here is the code that is required to build the same functionality using expression tree.
Expression sumExpr = Expression.Add( Expression.Constant(3), Expression.Constant(6) ); Console.WriteLine(Expression.Lambda<Func<int>>(sumExpr).Compile()());
