我正在编写一个解析工具来帮助我在为它进行 .net 绑定之前清理一个大型 VC++ 项目。

我正在使用 XML 编写器读取 xml 文件并将每个元素写入新文件。如果找到具有特定名称的元素，则它会执行一些代码并将输出值写入元素值。

到目前为止，它几乎可以工作，除了一件事：它没有复制属性。谁能告诉我为什么会这样？

这是应该复制/修改的示例（包括属性）：

    <?xml version="1.0" encoding="utf-8"?>
<Project DefaultTargets="Build" ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <ItemGroup Label="ProjectConfigurations">
    <ProjectConfiguration Include="Debug|Win32">
      <Configuration>Debug</Configuration>
      <Platform>Win32</Platform>
    </ProjectConfiguration>
    <ProjectConfiguration Include="Release|Win32">
      <Configuration>Release</Configuration>
      <Platform>Win32</Platform>
    </ProjectConfiguration>
  </ItemGroup>
  <PropertyGroup Label="Globals">
    <ProjectGuid>{57900E99-A405-49F4-83B2-0254117D041B}</ProjectGuid>
    <Keyword>Win32Proj</Keyword>
    <RootNamespace>libproj</RootNamespace>
  </PropertyGroup>

这是我得到的输出（无属性）：

<?xml version="1.0" encoding="utf-8"?>
<Project>
  <ItemGroup>
    <ProjectConfiguration>
      <Configuration>Debug</Configuration>
      <Platform>Win32</Platform>
    </ProjectConfiguration>
    <ProjectConfiguration>
      <Configuration>Release</Configuration>
      <Platform>Win32</Platform>
    </ProjectConfiguration>
  </ItemGroup>
  <PropertyGroup>
    <ProjectGuid>{57900E99-A405-49F4-83B2-0254117D041B}</ProjectGuid>
    <Keyword>Win32Proj</Keyword>
    <RootNamespace>libproj</RootNamespace>

这是我目前的代码。我已经尝试了所有可以想出的方法来编写属性。 

                string baseDir = (textBox2.Text + "\\" + safeFileName);
                string vcName = Path.GetFileName(textBox1.Text);
                string vcProj = Path.Combine(baseDir, vcName);

                using (XmlReader reader = XmlReader.Create(textBox1.Text))
                {
                    XmlWriterSettings settings = new XmlWriterSettings();
                    settings.OmitXmlDeclaration = true;
                    settings.ConformanceLevel = ConformanceLevel.Fragment;
                    settings.Indent = true;
                    settings.CloseOutput = false;

                    using (XmlWriter writer = XmlWriter.Create(vcProj, settings))
                    {

                        while (reader.Read())
                        {
                            switch (reader.NodeType)
                            {

                                    {
                                        string include = reader.GetAttribute("Include"); 
                                        string dirPath = Path.GetDirectoryName(textBox1.Text);
                                        Directory.SetCurrentDirectory(dirPath);
                                        string fullPath = Path.GetFullPath(include);
                                        //string dirPath = Path.GetDirectoryName(fullPath);

                                        copyFile(fullPath, 3);
                                        string filename = Path.GetFileName(fullPath);
                                        writer.WriteStartElement(reader.Name);

在 Soonts 发表评论后，我最终对命名空间进行了一些研究，并意识到为什么我的一个尝试不起作用。我必须事先指定命名空间，而不是让作者将其复制到阅读器 XML 文件中。这是我解决问题的方法：

                        string baseDir = (textBox2.Text + "\\" + safeFileName);
                        string vcName = Path.GetFileName(textBox1.Text);
                        string vcProj = Path.Combine(baseDir, vcName);

                        using (XmlReader reader = XmlReader.Create(textBox1.Text))
                        {
                            XmlWriterSettings settings = new XmlWriterSettings();
                            //settings.OmitXmlDeclaration = true;
                            settings.ConformanceLevel = ConformanceLevel.Auto;
                            settings.Indent = true;
                            settings.CloseOutput = false;
                            string nameSpace = "http://schemas.microsoft.com/developer/msbuild/2003";
                            using (XmlWriter writer = XmlWriter.Create(vcProj, settings))
                            {

                                while (reader.Read())

                                                Directory.SetCurrentDirectory(dirPath);
