ASP.NET中readonly与const的区别详解

public class Test
{
 public readonly string name = "George";
 public const string coname = "ABC Company LLC";
 public Test(string name)
 {
 // readonly 修饰的变量能且只能在 Constructor（构造函数）中被改变 
 this.name = name;
 }
 public string _name
 {
 get
 {
 return name;
 }
 //不可以对readonly修饰的变量进行Set操作 
 //set 
 //{ 
 // name = value; 
 //} 
 }
}
 
class Program
{
 static void Main(string[] args)
 {
 Test obj = new Test("Test");
 //readonly的变量不可以修改值，只能在 Constructor（构造函数）中被改变 
 //obj.name = "New Value"; 
 Console.WriteLine(obj.name); 
 //const 的变量直接通过对象访问，不需要实例化 
 Console.WriteLine(Test.coname);
 Console.Read();
 }
