CLR via C# 读书笔记 6-3 跨域访问的性能问题

以下代码演示了跨域访问的性能问题

大约不跨域比跨域快100多倍....

 

 AppDomain newDomain = AppDomain.CreateDomain("remote application domain", null, null);
            MarshalByRefType local = new MarshalByRefType();
            MarshalByRefType remote = (MarshalByRefType)newDomain.CreateInstanceAndUnwrap(Assembly.GetEntryAssembly().FullName, "TestConsole.MarshalByRefType");
            Stopwatch sw = null;
            int length = 10000000;
            int temp;

            sw = Stopwatch.StartNew();
            for (int i = 0; i < length; i++)
            {
                //local.SetValue(i);
                temp=local.GetValue();
            }
            Console.WriteLine(sw.ElapsedMilliseconds);

            sw = Stopwatch.StartNew();
            for (int i = 0; i < length; i++)
            {
                //remote.SetValue(i);
                temp = remote.GetValue();
            }
            Console.WriteLine(sw.ElapsedMilliseconds);
            return;
