c# 动态编译代码 执行脚本代码 关键字还会变色 // debug it step by step (F10, F11) using System; // for Console.WriteLine using System.Windows.Forms; // for MessageBox.Show, ... using System.Diagnostics; // for Debug.WriteLine using System.Collections.Generic; // for List // we can call static functions MessageBox.Show("Hello World!"); // output to DevStudio Output Console.WriteLine("Hello World!"); // same output over Debug Debug.WriteLine("Hello World!"); // we can define global var's var anystr = "Hello World {0} {1}"; int anynuber = 1; float anyfloat = 3.14f; // and we can use it Console.WriteLine(string.Format(anystr, anynuber, anyfloat)); // we can write functions string test1(int i, string s) { return s + " " + i; } double test2(double x) { double t = Math.Sin(x); // with local vars of course return t * t; }
