XmlWriter将奇怪的字符放在文档开始处 [英] XmlWriter putting strange chars at start of doc

问题描述

我正在使用XmlWriter，但是每次创建文档时，它会将这三个奇怪的字符放在文档的开头:

I''m using an XmlWriter but everytime I create a document it is putting these three strange characters at the beginning of my document:

</b><?xml version="1.0" encoding="utf-8"?>

有没有其他人看到过此消息和/或知道如何解决它?！?！?！

Has anyone else seen this and/or know how to fix it?!?!?!

</b><?xml version ="1.0" encoding ="utf-8"?>

这些是UTF-8前缀字符0xEF，0xBB，0xBF，告诉任何读取文件的人如何对其进行解码.请注意，UTF-8不是Unicode.

These are the UTF-8 prefix characters 0xEF,0xBB,0xBF which tells anyone reading the file how to decode it. Note that UTF-8 is NOT Unicode.

当我将编码更改为Unicode时，这些字符不见了.

When I changed encoding to Unicode, these chars are gone.

请注意，Unicode还使用前缀字符(0xFF 0xFE)来标识编码.无论哪种情况(UTF-8或Unicode)，如果您使用正确的C#/.NET类进行读/写，您都不必担心，因为该框架将为您正确地管理它.如果您要编写自己的读取器/写入器，请确保正确管理编码密钥.

Be aware that Unicode also uses prefix characters (0xFF 0xFE) to identify the encoding. In either case (UTF-8 or Unicode) if you are reading/writing with the correct C#/.NET classes you don''t need to worry about this as the framework will manage it correctly for you. If you are writing your own reader/writer then make sure you manage the encoding keys correctly.

它们是用于标识文件以 Unicode存储的事实的标记，和字节顺序 UTF-8. ((因此，它们应该在那里))

They are the markers used to identify the fact that the file is stored in Unicode, and the byte order UTF-8. (( So, they should be there ))
