Question

为什么每次我尝试向节点添加新属性时，都会添加额外的属性"xmlns="？有什么方法可以阻止这种情况吗？

public void changeProjToAssembly(string projPath,string projRefName)
{
    XmlDocument doc = new XmlDocument();
    doc.Load(projPath);

    XmlNode projectReferenceNode;
    XmlNode itemGroupNode;
    XmlNode root = doc.DocumentElement;

    string s = doc.DocumentElement.GetNamespaceOfPrefix("");
    XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc.NameTable);
    nsmgr.AddNamespace("rs", s);

    projectReferenceNode = root.SelectSingleNode("/rs:Project/rs:ItemGroup/rs:ProjectReference[rs:Name='GS_POSLibrary1']", nsmgr);
    itemGroupNode = root.SelectSingleNode("/rs:Project/rs:ItemGroup[rs:ProjectReference/rs:Name='GS_POSLibrary1']", nsmgr);

    XmlElement newCd = doc.CreateElement("Reference");
    newCd.SetAttribute("Include", "dasdsad");           

    newCd.InnerXml = "<HintPath>" + ".//sadssa/asdsad" + "</HintPath>"+
    "<HintPath>" + ".//sadssa/asdsad" + "</HintPath>" +
     "<HintPath>" + ".//sadssa/asdsad" + "</HintPath>";

    itemGroupNode.ReplaceChild(newCd, projectReferenceNode);

    Console.WriteLine("Display the modified XML document....");

    doc.Save(Console.Out);           
}

XML：

<ItemGroup>
<ProjectReference Include="..\common\librarycomponents\exportdb\GenerateDocLibrary.vbproj">
  <Project>{9B3C9E8B-436B-4A16-87A8-E72CB2FFC6E6}</Project>
  <Name>GS_POSLibrary</Name>
  <Private>False</Private>
</ProjectReference>
<Reference Include="dasdsad" xmlns="">//I only need the Include Atrribute
  <HintPath>.//sadssa/asdsad</HintPath>
  <HintPath>.//sadssa/asdsad</HintPath>
  <HintPath>.//sadssa/asdsad</HintPath>
</Reference>

Answer 1

您在空命名空间中创建了Reference元素，而不是在rs命名空间中。尝试使用doc.CreateElement("Reference", s);

Answer 2

我认为这是因为您在此处向文档中添加了一个空命名空间：

string s = doc.DocumentElement.GetNamespaceOfPrefix("");
XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc.NameTable);
nsmgr.AddNamespace("rs", s);

然后当你附加那个节点时，它会附加你添加的命名空间。
