问题 What ways do I have in .net to run code from string? Console.WriteLine(Compile("1 + 2 * 3")); // results is 7. What other options do we have? C# - Compile the code on runtime? IronRuby / IronPython? F#? 回答1: So, the dynamic languages like IronRuby and IronPython make it very easy to do what you want. Create a script engine and execute the string. Easy as that.

问题 I am loading my assemblies at run time and I am also using Instance Activator to get the code at the runtime. Following code will summerize what I am doing: dynamic powerTool; System.Reflection.Assembly assembly = System.Reflection.Assembly.LoadFrom( @"C:\Users\c_desaik\Desktop\PowerTool.exe"); Type type = assembly.GetType("PowerTool.Automation"); powerTool = Activator.CreateInstance(type); Now, as you have noticed, Powertool has been declared as dynamic because I do not want my code to fail

问题 I already have a windows service running with a System.Timers.Timer that do a specific work. But, I want some works to run at the same time, but in different threads. I've been told to create a different System.Timers.Timer instance. Is this correct?
