UTF - 8的大写？ [英] utf-8 in uppercase?

问题描述

$ b $这是我想做的更改的一个更改，我想知道如何使用UTF-8大写而不是utf-8生成生成的xml文件？ b

  XmlWriterSettings settings = new XmlWriterSettings（）; 
 settings.Encoding = Encoding.UTF8; 
 settings.Indent = true; 
 settings.IndentChars =\t; 
 
 XmlWriter writeXML = XmlWriter.Create（test_file.xml，settings）; 
 writeXML.WriteStartDocument（false）; 
 writeXML.WriteComment（fileLicense）; 
 writeXML.WriteStartElement（templates）; 
 writeXML.WriteAttributeString（xmlns，xsi，null，http://www.w3.org/2001/XMLSchema-instance）; 
 writeXML.WriteAttributeString（xsi，noNamespaceSchemaLocation，null，test_file.xsd）; 
 writeXML.WriteEndElement（）; 
 writeXML.WriteEndDocument（）; 
 writeXML.Close（）; 
  

解决方案

我发现这个博客文章。看来这是你想要的。

  public class UpperCaseUTF8Encoding：UTF8Encoding 
 {

 //他使用反射器来理解编码类
 // 
的层次结构。返回Reflector，我注意到Encoding.WebName是用于
 //写出编码字符串。我现在创建一个UTF8Encoding的后代类。 
 //这个类列在下面。现在，我只是调用XmlTextWriter，为编码类型传递
 // UpperCaseUTF8Encoding.UpperCaseUTF8，并且一切正常工作
 //。 -  Dan Miser 
 
 public override string WebName 
 {
 get {return base.WebName.ToUpper（）; } 
} 
 
 public static UpperCaseUTF8Encoding UpperCaseUTF8 
 {
 get 
 {
 if（upperCaseUtf8Encoding == null）{
 upperCaseUtf8Encoding = new UpperCaseUTF8Encoding（）; 
} 
返回upperCaseUtf8Encoding; 
} 
} 
 
 private static UpperCaseUTF8Encoding upperCaseUtf8Encoding = null; 
 
 
 
 
 
 $ b要使用此自定义编码，您需要使用XMLTextWriter作为目标XDocument保存方法。 
 
 
  //此部分未显示在博客
 
 var xDoc = XDocument中。负载（xmlDocNm）; //这是你的xml路径值
 //在这里改变XML文档
 
 // .Net用小写字母utf-8写XML声明。 
 //<？xml version =1.0encoding =utf-8？> 
 //这不是重头戏的问题，但NiceForm期望的是大写。 
 //<？xml version =1.0encoding =UTF-8？> 
 //我们使用一个带有自定义编码的XMLWriter来设置UTF 
 
 //设置各种选项来检索所需的输出
 var settings = new XmlWriterSettings {
编码=新的UpperCaseUTF8Encoding（），//这个例子的键设置选项
 
 NewLineHandling = System.Xml.NewLineHandling.Replace，
 NewLineOnAttributes = true，
 Indent = true / /为每个元素生成新行
}; 
 
 using（var xmlWriter = XmlTextWriter.Create（xmlDocNm，settings））{
 xDoc.Save（xmlWriter）; 
} 
  
 
This is more of a cosmetic change that I wanted to make and I was wondering how could I make the generated xml file with UTF-8 uppercase instead of utf-8 lowercase ?
        XmlWriterSettings settings = new XmlWriterSettings();
        settings.Encoding = Encoding.UTF8;
        settings.Indent = true;
        settings.IndentChars = "\t";

        XmlWriter writeXML = XmlWriter.Create("test_file.xml", settings);
        writeXML.WriteStartDocument(false);
        writeXML.WriteComment(fileLicense);
        writeXML.WriteStartElement("templates");
        writeXML.WriteAttributeString("xmlns", "xsi", null, "http://www.w3.org/2001/XMLSchema-instance");
        writeXML.WriteAttributeString("xsi", "noNamespaceSchemaLocation", null, "test_file.xsd");
        writeXML.WriteEndElement();
        writeXML.WriteEndDocument();
        writeXML.Close();

解决方案
I found this blog post. Seems it is what you want.
public class UpperCaseUTF8Encoding : UTF8Encoding
{
  // Code from a blog http://www.distribucon.com/blog/CategoryView,category,XML.aspx
  //
  // Dan Miser - Thoughts from Dan Miser
  // Tuesday, January 29, 2008 
  // He used the Reflector to understand the heirarchy of the encoding class
  //
  //      Back to Reflector, and I notice that the Encoding.WebName is the property used to
  //      write out the encoding string. I now create a descendant class of UTF8Encoding.
  //      The class is listed below. Now I just call XmlTextWriter, passing in
  //      UpperCaseUTF8Encoding.UpperCaseUTF8 for the Encoding type, and everything works
  //      perfectly. - Dan Miser

  public override string WebName
  {
    get { return base.WebName.ToUpper(); }
  }

  public static UpperCaseUTF8Encoding UpperCaseUTF8
  {
    get
    {
      if (upperCaseUtf8Encoding == null) {
        upperCaseUtf8Encoding = new UpperCaseUTF8Encoding();
      }
      return upperCaseUtf8Encoding;
    }
  }  

  private static UpperCaseUTF8Encoding upperCaseUtf8Encoding = null;
}
To use this custom encoding you need to use an XMLTextWriter as the destination to the XDocument Save method.
// This section not shown in the blog

var xDoc = XDocument.Load(xmlDocNm); //This is your xml path value 
// Changes to XML Document here

// .Net writes the XML declaration using lower case utf-8.
//  <?xml version="1.0" encoding="utf-8"?>
// It is not suppesed to matter but NiceForm expects the delcaration to be uppercase.
//  <?xml version="1.0" encoding="UTF-8"?>
// We are using a XMLWriter with a custom Encoding to captialize the UTF

// Set various options to retrive the desired output
var settings = new XmlWriterSettings {
  Encoding = new UpperCaseUTF8Encoding(), // Key setting option for this example

  NewLineHandling = System.Xml.NewLineHandling.Replace,
  NewLineOnAttributes = true,
  Indent = true                           // Generate new lines for each element
};

using (var xmlWriter =XmlTextWriter.Create(xmlDocNm, settings)) {
  xDoc.Save(xmlWriter);
}
