FileStream.Position使用后检查StreamWriter.Write()，我在给定值中存在一些不准确性，已针对产生的文件和使用的字符串的长度进行了验证：string MyText = "\"aaqnt - bra\"\t\"kkaaknc qzxukrnt\"\t\"kkaaknc qzx xrrqtrq zn\"\t\"arhkxar kq Nz.\"\t\"qkstrkkutkzn xhqnnra\"\t\"knazkxr xqtrczra\"\t\"arhkxar Nrt arkxr\"\t\"qkzNrtarkxr\"\t\"TztaqTqkzunt\"\t\"aqT %\"\t\"Nrtknazkxrqkzunt\"\r\n\"8009\"\t\"9000099989\"\t\"9098-09-99\"\t\"kHbkF09F9Hb009890\"\t\"09\"\t\"k\"\t\"09,000\"\t\"\"\t\"9,000\"\t\"0.00%\"\t\"00,000\"\r\n\"8008\"\t\"9000099009\"\t\"9098-09-99\"\t\"Rbakk9Hr9J0999098\"\t\"09\"\t\"k\"\t\"99,900\"\t\"\"\t\"0,990\"\t\"0.00%\"\t\"98,990\"\r\n\"8008\"\t\"9000099999\"\t\"9098-09-99\"\t\"JTNk99Hb9J0009899\"\t\"09\"\t\"k\"\t\"99,800\"\t\"\"\t\"9,990\"\t\"0.00%\"\t\"98,990\"\r\n\"8008\"\t\"9000090988\"\t\"9098-09-99\"\t\"Rbakk9Hr9J0999098\"\t\"09\"\t\"k\"\t\"99,900\"\t\"\"\t\"0,990\"\t\"0.00%\"\t\"98,990\"\r\n\"8000\"\t\"9000090990\"\t\"9098-09-99\"\t\"JTNk99Hb9J0090909\"\t\"09\"\t\"k\"\t\"99,999\"\t\"\"\t\"9,899.90\"\t\"0.00%\"\t\"99,090.90\"\r\n\"8000\"\t\"9000090099\"\t\"9098-09-99\"\t\"kR0xW8kk8J0099900\"\t\"09\"\t\"k\"\t\"99,900\"\t\"\"\t\"9,900\"\t\"0.00%\"\t\"09,000\"\r\n\"8000\"\t\"9000090900\"\t\"9098-09-99\"\t\"JTNk99Hb9J0099098\"\t\"09\"\t\"k\"\t\"99,800\"\t\"\"\t\"9,990\"\t\"0.00%\"\t\"98,990\"\r\n\"8000\"\t\"9000090000\"\t\"9098-09-99\"\t\"kHFk99F00J9099009\"\t\"09\"\t\"k\"\t\"99,900\"\t\"\"\t\"9,990\"\t\"0.00%\"\t\"09,090\"\r\n\"8000\"\t\"9000090090\"\t\"9098-09-int TextLengthInBytes = Encoding.UTF8.GetByteCount(MyText); // 5127.FileStream Nonsense = new FileStream("D:\\180415_21569.txt", FileMode.CreateNew, FileAccess.Write, FileShare.None);StreamWriter Insanity = new StreamWriter(Nonsense, Encoding.UTF8);Insanity.Write(MyText); // Position 0 => 5123.Insanity.Flush();Nonsense.Dispose();使用此示例字符串，差异（5123）比正确值（5127）小4。用我的原始字符串，它少了7个（5120）。我想知道造成这种差异的原因，以及解决该差异的可能性。似乎与默认缓冲无关，因为结果值有时是奇数，而不是偶数，并且是在进行微跳转。我正在考虑将GetByteCount上面显示的作为跟踪真实位置的一种替代方法，尽管它与实际的兴趣点/代码有所不同，并假设这些值始终相等，并且很可能是完全临时的。
