如何在 C# 中编写此 java 代码

Question

我有这个 java 代码，我想将其转换为 c#：

ByteArrayOutputStream baos = new ByteArrayOutputStream();
PrintStream ps = new PrintStream(baos);
ps.printf("\n\n+++++ %s %s\n",Environment.UserName, new SimpleDateFormat("MM/dd/yyyy HH:mm:ss aa").format(new Date()));

就像是：

  // You can use "using" blocks guarantee streams are disposed (like try/finally { boas.Close(); })
  using (var baos = new MemoryStream())
  {
    // Stream encodes as UTF-8 by default; specify other encodings in this constructor
    using (var ps = new StreamWriter(baos))
    {
      // Format string almost the same, but 'tt' for 'am/pm'
      // Could also use move formatting into
      //    DateTime.Now.ToString("MM/dd/yyyy HH:mm:ss tt")
      // or ToLongDateString and ToLongTimeString for locale-defined formats
      ps.Write("\n\n+++++ {0} {1:MM/dd/yyyy HH:mm:ss tt}\n", Environment.UserName, DateTime.Now);

      // Need to close or flush the StreamWriter stream before the bytes will
      // appear in the MemoryStream
      ps.Close();
    }

    // Extract bytes from MemoryStream
    var bytes = baos.ToArray();
  }
