问题 In order to comply with HIPAA regulations, we need to send email from an external site (outside the firewall) to an internal Exchange server (inside the firewall).

问题 I can do an eval(\"something()\"); to execute the code dynamically in JavaScript. Is there a way for me to do the same thing in C#? An example of what I am trying to do is: I have an integer variable (say i ) and I have multiple properties by the names: \"Property1\", \"Property2\", \"Property3\", etc. Now, I want to perform some operations on the \" Property i \" property depending on the value of i .
