不必要的？当我尝试动态创建xml时 [英] Unnecessary ? comes when i try to create xml dynamically

问题描述

我正在使用以下代码。这里的问题是在执行不必要的''？''符号时。

I am using the code below. The problem here is while executing an unnecessary ''?'' sign comes.

XmlWriterSettings wSettings = new XmlWriterSettings();
wSettings.Indent = true;
MemoryStream ms = new MemoryStream();
XmlWriter xw = XmlWriter.Create(ms, wSettings);// Write Declaration
xw.WriteStartDocument();

// Write the root node
xw.WriteStartElement("Request");
xw.WriteStartAttribute("RequestID");
xw.WriteString("7");
xw.WriteStartAttribute("AuthenticationKey");
xw.WriteString("asdf;lkj");
// Write the books and the book elements
xw.WriteStartElement("diagnosisData");
xw.WriteStartAttribute("IDCL_Code");
xw.WriteString("101");
xw.WriteEndAttribute();

xw.WriteEndElement();

// Close the document
xw.WriteEndDocument();

// Flush the write
xw.Flush();

Byte[] buffer = new Byte[ms.Length];
buffer = ms.ToArray();
string xmlOutput = System.Text.Encoding.UTF8.GetString(buffer);
Console.WriteLine(xmlOutput);
Console.ReadKey();

推荐答案

你的XML文件包含一些超出ASCII的Unicode字符，控制台当时不会显示，替换它们通常是''？''。你需要让控制台显示Unicode：



这样做：

It your XML file contains some Unicode characters beyond ASCII, the console won''t show then, replacing them by ''?'', as usually. You need to make console showing Unicode:

Do this:

System.Console.OutputEncoding = System.Text.Encoding.Unicode;

这令人困惑。 System.Text.Encoding.Unicode 并不真正意味着Unicode，但是，在那个奇怪的Microsoft行话中，它意味着Unicode的UTF-16LE编码。 Unicode本身不是编码。请参阅：

http://www.Unicode.org [ ^ ]，

This is confusing. System.Text.Encoding.Unicode does not really mean Unicode, but, in that weird Microsoft jargon, it means UTF-16LE encoding of Unicode. Unicode itself is not encoding. Please see:

我没有确切的理由'''''。我只是通过删除第零位置的元素来解决这个问题。我认为其原因与Sergey Alexandrovich所述相同。



xmlOutput = xmlOutput.Remove（0,1）;

I didn''t got the exact reason for that ''?''. I just got out of that by removing the element at zeroth position. I think the reason for that is same as stated by Sergey Alexandrovich.

xmlOutput = xmlOutput.Remove(0, 1);
