使用 C# 行从数据库中检索 XML 列

Question

我对 DB 运行查询，它返回 1 行 2 列。每列都有 XML（脚本），我需要在其中检索到（理想情况下是字符串），然后对 DB 执行。 我需要检索到的字符串具有行和格式，就像我从 SQL 管理工作室复制一样。

来自 SQL 管理工作室的部分 XMLresult 我需要这种格式。替换：XXXXXX

<message>
  <header>
    <meta version="02" type="OrMessageUdalost_Int" />
    <sender name="XXXXXX" appid="XXXXXX" netid="XXXXXX" />
    <receiver name="XXXXXX" appid="XXXXXX" netid="XXXXXX" />
    <timestamp date="XXXXXX" time="10:11:00" gmt="+XXXXXX" />
    <options priority="4" props="XXXXXX" limit="100" />
  </header>
  <content>
    <q1:orMessageUdalost_Int xmlns:q1="XXXXXX" verze="v_2.11">
      <hlavicka>
        <idDatovaVeta>XXXXXX</idDatovaVeta>
        <datumVytvoreni>XXXXXX</datumVytvoreni>
        <ciselnikAktualizace>false</ciselnikAktualizace>
        <ostrovniRezim>false</ostrovniRezim>
        <puvodceDV>
          <id>XXXXXX</id>
          <kod>XXXXXX</kod>
        </puvodceDV>
        <idPuvodniDV>XXXXXX</idPuvodniDV>
        <puvodniDatumVytvoreni>XXXXXX</puvodniDatumVytvoreni>
        <stavUdalosti>XXXXXX</stavUdalosti>
        <stavSlozky>
          <slozka>
            <id>XXXXXX</id>
            <kod>XXXXXX</kod>
          </slozka>
          <isStav>XXXXXX</isStav>
        </stavSlozky>
      </hlavicka>
      <teloFull>

感谢您的建议。

Answer 1

所以关键是要获得正确的缩进？

在这种情况下，我建议您查看以下 SO 线程：

Format XML string to print friendly XML string

关键是你需要缩进，可以通过XmlTextWrite.Formatting = Formatting.Indented选项来实现。

使用 XML 序列化程序。见下面的代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Serialization;
using System.IO;

namespace ConsoleApplication193
{
    class Program
    {
        const string INPUT_FILENAME = @"c:\temp\test.xml";
        const string OUTPUT_FILENAME = @"c:\temp\test1.xml";
        static void Main(string[] args)
        {
            string xml = File.ReadAllText(INPUT_FILENAME);
            StringReader sReader = new StringReader(xml);

            XmlReader reader = XmlReader.Create(sReader);
            XmlSerializer serializer = new XmlSerializer(typeof(Message));
            Message message = (Message)serializer.Deserialize(reader);

            //write
            XmlSerializerNamespaces names = new XmlSerializerNamespaces();
            names.Add("q1", "XXXXXX");

            XmlWriterSettings settings = new XmlWriterSettings();
            settings.Indent = true;
            MemoryStream stream = new MemoryStream();
            XmlWriter writer = XmlWriter.Create(stream);
            serializer.Serialize(writer,message,names);
            byte[] buffer = new byte[stream.Length];
            stream.Position = 0;
            stream.Read(buffer, 0, (int)stream.Length);
            string output = Encoding.UTF8.GetString(buffer);
          
        }
    }
