Question

我想使用批处理文件编译java程序。如果程序不需要任何输入但在需要输入时创建死锁条件，则代码有效这是代码：

    public void compilefile(ref System.Windows.Controls.RichTextBox rtb,ref TabItem tabitem)
    {
        var range = new TextRange(rtb.Document.ContentStart, rtb.Document.ContentEnd);

        FileInfo filetocompile = new FileInfo(Path.GetTempPath() + tabitem.Header.ToString());
        using (FileStream fs = filetocompile.Open(FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.ReadWrite))
        {
            range.Save(fs, System.Windows.DataFormats.Text);
            fs.Close();
        }

     try{

            pf = new ProcessStartInfo(@"E:\com.bat");
            pf.FileName = @"E:\com.bat";
            pf.Arguments = string.Format("{0} {1} {2} {3} {4}", "\"C:\\Program Files (x86)\\Java\\jdk1.7.0_13\\bin\\\"", "javac", tabitem.Header.ToString(), "java", tabitem.Header.ToString().Substring(0, tabitem.Header.ToString().LastIndexOf('.')));
            pf.CreateNoWindow = true;
            pf.ErrorDialog = false;
            pf.UseShellExecute = false;
            pf.RedirectStandardInput = true;
            pf.RedirectStandardOutput = true;
            pf.RedirectStandardError = true;
            pf.WorkingDirectory = Path.GetTempPath();
            p = new Process();
            p.StartInfo = pf;
            p.Start();
            input = p.StandardInput;
            string inputstring = "";
            input.AutoFlush = true;

            do
            {
                if (p.StandardError.ReadToEnd() != "")
                {
                    consoleTextBlock.IsDocumentEnabled = false;
                    consoleTextBlock.AppendText(p.StandardOutput.ReadToEnd());
                    consoleTextBlock.AppendText(p.StandardError.ReadToEnd());
                 }
                else
                {
                    consoleTextBlock.AppendText(p.StandardOutput.ReadToEnd());
                    consoleTextBlock.AppendText(p.StandardError.ReadToEnd());

                }

                consoleTextInput.Focus();
                consoleTextBlock.ScrollToEnd();
                consoleTextBlock.IsReadOnly = true;
                System.Windows.MessageBox.Show(p.ExitCode.ToString());
            } while (p.HasExited != true);
        }
        catch (Exception ex)
        {
            System.Windows.MessageBox.Show(ex.ToString());

        }
    }

我应该使用什么来重定向输入？请尽快帮忙。

先输入，然后在事件后读取两个输出流，如下所示：

    //..
    string[] inputLines = {"your", "input", "goes", "here"}
    //..
    //..
    p.Start();

    using (StreamWriter sw = p.StandardInput)
    {
        if (sw.BaseStream.CanWrite)
            foreach(string line in inputLines) sw.WriteLine(line);
    }
    string output = "+"; 
    string outputErr = "-";
    output = p.StandardOutput.ReadToEnd();
    outputErr = p.StandardError.ReadToEnd();
    p.WaitForExit();

在c＃中重定向过程StandardInput，StandardOutput和StandardError
