我正在 silverlight 4 和 WinForms (net4) 中构建 IronRuby 控制台。我可以毫无问题地重定向输出:
MyRuntime = Ruby.CreateRuntime();
msOutput = new MemoryStream();
MyRuntime.IO.SetOutput(msOutput, Encoding.UTF8);
MyEngine = MyRuntime.GetEngine("rb");
MySource = MyEngine.CreateScriptSourceFromString("a='123'\nputs a", SourceCodeKind.Statements);
MySource.Execute();
textBox2.Text = ReadFromStream(msOutput);
现在,我也想重定向输入,但总是从脚本中得到一个“nil”:
MyRuntime = Ruby.CreateRuntime();
msOutput = new MemoryStream();
msInput = new MemoryStream();
MyRuntime.IO.SetOutput(msOutput, Encoding.UTF8);
MyRuntime.IO.SetInput(msInput, Encoding.UTF8);
MyEngine = MyRuntime.GetEngine("rb");
MySource = MyEngine.CreateScriptSourceFromString("a=gets\nputs a", SourceCodeKind.Statements);
byte[] byteArray = Encoding.UTF8.GetBytes("123");
msInput.Write(byteArray, 0, byteArray.Length);
MySource.Execute();
textBox2.Text = ReadFromStream(msOutput);
我找不到任何重定向输入的样本,你能发一个例子吗?谢谢你。
