我想添加和删除从C＃.csproj的文件元素。该文件部分，如下所示。可有人告诉我怎么可以做以下两件事情？

 ＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT;项目ToolsVersion =3.5DefaultTargets =建设
的xmlns =htt​​p://schemas.microsoft.com/developer/msbuild/2003＆GT;
   ＆LT;的PropertyGroup＆GT;
      ＆lt;结构状态='$（配置）'==''＆GT;调试和LT; /结构＆gt;
＆LT; /的PropertyGroup＆GT;
＆LT; ItemGroup＆GT;
   ＆lt;参考包括=System.Data这/＆GT;
   ＆lt;参考包括=System.Deployment/＆GT;
＆LT; / ItemGroup＆GT;
＆LT; ItemGroup＆GT;
   ＆LT;编译包括=生成\ DatabaseContext.cs/＆GT;
   ＆LT;编译包括=生成\ EntityClasses.cs/＆GT;
   ＆LT;编译包括=生成\ Extensions.cs/＆GT;
   ＆LT;编译包括=架构\ Column.cs/＆GT;
   ＆LT;编译包括=架构\ EntityRef.cs/＆GT;
   ＆LT;编译包括=SerializedData \ Tables.xml/＆GT; //我想补充这
＆LT; / ItemGroup＆GT;
＆LT;导入项目=$（MSBuildToolsPath）\ Microsoft.CSharp.targets/＆GT;
＆LT; /项目＆GT;
 

解决方案

您可以通过以下方式添加您的指示行：

 的XNamespace NS =htt​​p://schemas.microsoft.com/developer/msbuild/2003;
XDOC的XDocument = XDocument.Load（文件名）;

。VAR B = xDoc.Descendants（NS +编译）第一（）;

b.Parent.Add（
    新的XElement（NS +编译，
        新XAttribute（包含@SerializedData \ Tables.xml）
    ）
）;

xDoc.Save（文件名）;
 

要删除您指定的行，试试这个：

 的XNamespace NS =htt​​p://schemas.microsoft.com/developer/msbuild/2003;
XDOC的XDocument = XDocument.Load（文件名）;

变种B = xDoc.Descendants（NS +编译）
    。凡（EL =＆GT; el.Attribute（包含）值== @SerializedData \ Tables.xml）;

如果（B！= NULL）
{
    b.Remove（）;
    xDoc.Save（文件名）;
}
 

I am trying to add and delete elements from a C# .csproj file. The file, in part, appears below. Can someone show me how I can do the following two things?

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="3.5" DefaultTargets="Build" 
xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
   <PropertyGroup>
      <Configuration Condition=" '$(Configuration)' == '' ">Debug</Configuration>
</PropertyGroup>
<ItemGroup>
   <Reference Include="System.Data" />    
   <Reference Include="System.Deployment" />
</ItemGroup>
<ItemGroup>
   <Compile Include="Generate\DatabaseContext.cs" />
   <Compile Include="Generate\EntityClasses.cs" />
   <Compile Include="Generate\Extensions.cs" />
   <Compile Include="Schema\Column.cs" />
   <Compile Include="Schema\EntityRef.cs" />
   <Compile Include="SerializedData\Tables.xml" />  //I want to add this
</ItemGroup>
<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />
</Project>

You can add your indicated line in the following way:

XNamespace ns = "http://schemas.microsoft.com/developer/msbuild/2003";
XDocument xDoc = XDocument.Load(fileName);

var b = xDoc.Descendants(ns + "Compile").First();

b.Parent.Add(
    new XElement(ns + "Compile", 
        new XAttribute("Include", @"SerializedData\Tables.xml")
    )
);

xDoc.Save(fileName);

To remove your indicated line, try this:

XNamespace ns = "http://schemas.microsoft.com/developer/msbuild/2003";
XDocument xDoc = XDocument.Load(fileName);

var b = xDoc.Descendants(ns + "Compile")
    .Where(el => el.Attribute("Include").Value == @"SerializedData\Tables.xml");

if (b != null)
{
    b.Remove();
    xDoc.Save(fileName);
}
