.vcxproj.filters 误删后如何重建

背景：

今天碰到这样一种情况，我在删除这个VS文件夹下的.user文件时，不小心把.vcxproj.filters也删除了。当然为什么删.user呢，因为换电脑了。
删除之后，我发现：我的解决方案目录变成这样了：

对比一下，以前的我的是这样的：

然后，有那么一刹那，我慌了，虽然这个东西对于开发没有什么影响，但是我觉得看着很不舒服，找起源文件和头文件还有ui文件来，很不好找，我不喜欢这样。
先说一下，我找了半天，他们所处的情况都是这样的：
首先，我的.vcxproj.filters 文件没有被动过，然后我点击这个按钮就可以解决问题：

但是我的不是啊，我把文件删了啊。

准备开始：

于是，我在想，如何进行灾后重建啊：
第一步，先看一下这个例子：

<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <ItemGroup>
    <Filter Include="Source Files">
      <UniqueIdentifier>{4FC737F1-C7A5-4376-A066-2A32D752A2FF}UniqueIdentifier>
      <Extensions>cpp;c;cc;cxx;def;odl;idl;hpj;bat;asm;asmxExtensions>
    Filter>
    <Filter Include="Header Files">
      <UniqueIdentifier>{93995380-89BD-4b04-88EB-625FBE52EBFB}UniqueIdentifier>
      <Extensions>h;hh;hpp;hxx;hm;inl;inc;ipp;xsdExtensions>
    Filter>
    <Filter Include="Resource Files">
      <UniqueIdentifier>{67DA6AB6-F800-4c08-8B7A-83BB121AAD01}UniqueIdentifier>
      <Extensions>rc;ico;cur;bmp;dlg;rc2;rct;bin;rgs;gif;jpg;jpeg;jpe;resx;tiff;tif;png;wav;mfcribbon-msExtensions>
    Filter>
  ItemGroup>
  <ItemGroup>
    <ClInclude Include="MFCApplication1.h">
      <Filter>Header FilesFilter>
    ClInclude>
    <ClInclude Include="MFCApplication1Dlg.h">
      <Filter>Header FilesFilter>
    ClInclude>
    <ClInclude Include="stdafx.h">
      <Filter>Header FilesFilter>
    ClInclude>
    <ClInclude Include="targetver.h">
      <Filter>Header FilesFilter>
    ClInclude>
    <ClInclude Include="Resource.h">
      <Filter>Header FilesFilter>
    ClInclude>
  ItemGroup>
  <ItemGroup>
    <ClCompile Include="MFCApplication1.cpp">
      <Filter>Source FilesFilter>
    ClCompile>
    <ClCompile Include="MFCApplication1Dlg.cpp">
      <Filter>Source FilesFilter>
    ClCompile>
    <ClCompile Include="stdafx.cpp">
      <Filter>Source FilesFilter>
    ClCompile>
  ItemGroup>
  <ItemGroup>
    <ResourceCompile Include="MFCApplication1.rc">
      <Filter>Resource FilesFilter>
    ResourceCompile>
  ItemGroup>
  <ItemGroup>
    <None Include="res\MFCApplication1.rc2">
      <Filter>Resource FilesFilter>
    None>
  ItemGroup>
  <ItemGroup>
    <Image Include="res\MFCApplication1.ico">
      <Filter>Resource FilesFilter>
    Image>
  ItemGroup>
Project>

乍一看，这有点乱啊！
别慌！慢慢来：

1、打开我的.vcxproj.filters 文件(先将VS关闭)

将下面这行语句复制到文件中：

<Project ToolsVersion="Current" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <ItemGroup>
    <Filter Include="Form Files">
      <UniqueIdentifier>{99349809-55BA-4b9d-BF79-8FDBB0286EB3}UniqueIdentifier>
      <Extensions>uiExtensions>
    Filter>
    <Filter Include="Source Files">
      <UniqueIdentifier>{4FC737F1-C7A5-4376-A066-2A32D752A2FF}UniqueIdentifier>
      <Extensions>cpp;c;cc;cxx;def;odl;idl;hpj;bat;asm;asmxExtensions>
    Filter>
    <Filter Include="Header Files">
      <UniqueIdentifier>{93995380-89BD-4b04-88EB-625FBE52EBFB}UniqueIdentifier>
      <Extensions>h;hh;hpp;hxx;hm;inl;inc;ipp;xsdExtensions>
    Filter>
    <Filter Include="Resource Files">
      <UniqueIdentifier>{67DA6AB6-F800-4c08-8B7A-83BB121AAD01}UniqueIdentifier>
      <Extensions>rc;ico;cur;bmp;dlg;rc2;rct;bin;rgs;gif;jpg;jpeg;jpe;resx;tiff;tif;png;wav;mfcribbon-msExtensions>
    Filter>
    <Filter Include="Resource Files">
      <UniqueIdentifier>{D9D6E242-F8AF-46E4-B9FD-80ECBC20BA3E}UniqueIdentifier>
      <Extensions>qrc;*Extensions>
      <ParseFiles>falseParseFiles>
    Filter>
  ItemGroup>
Project>

2、打开VS

这个时候你关闭文件夹，它会提示你保存，那么你再打开.vcxproj.filters文件：

<Project ToolsVersion="Current" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <ItemGroup>
    <Filter Include="Form Files">
      <UniqueIdentifier>{99349809-55BA-4b9d-BF79-8FDBB0286EB3}UniqueIdentifier>
      <Extensions>uiExtensions>
    Filter>
    <Filter Include="Source Files">
      <UniqueIdentifier>{4FC737F1-C7A5-4376-A066-2A32D752A2FF}UniqueIdentifier>
      <Extensions>cpp;c;cc;cxx;def;odl;idl;hpj;bat;asm;asmxExtensions>
    Filter>
    <Filter Include="Header Files">
      <UniqueIdentifier>{93995380-89BD-4b04-88EB-625FBE52EBFB}UniqueIdentifier>
      <Extensions>h;hh;hpp;hxx;hm;inl;inc;ipp;xsdExtensions>
    Filter>
    <Filter Include="Resource Files">
      <UniqueIdentifier>{67DA6AB6-F800-4c08-8B7A-83BB121AAD01}UniqueIdentifier>
      <Extensions>rc;ico;cur;bmp;dlg;rc2;rct;bin;rgs;gif;jpg;jpeg;jpe;resx;tiff;tif;png;wav;mfcribbon-msExtensions>
    Filter>
    <Filter Include="Resource Files">
      <UniqueIdentifier>{D9D6E242-F8AF-46E4-B9FD-80ECBC20BA3E}UniqueIdentifier>
      <Extensions>qrc;*Extensions>
      <ParseFiles>falseParseFiles>
    Filter>
  ItemGroup>
  <ItemGroup>
    <ClCompile Include="myQGraphicsView.cpp">
      <Filter>Source FilesFilter>
    ClCompile>
    <ClCompile Include="myQGraphicsViewB.cpp">
      <Filter>Source FilesFilter>
    ClCompile>
    <ClCompile Include="myQTwidget.cpp">
      <Filter>Source FilesFilter>
    ClCompile>
    <ClCompile Include="keyboardEvent.cpp">
      <Filter>Source FilesFilter>
    ClCompile>
    <ClCompile Include="myStaticalTable.cpp">
      <Filter>Source FilesFilter>
    ClCompile>
    <ClCompile Include="reCheck.cpp">
      <Filter>Source FilesFilter>
    ClCompile>
    <ClCompile Include="main.cpp">
      <Filter>Source FilesFilter>
    ClCompile>
  ItemGroup>
  <ItemGroup>
    <ClInclude Include="keyboardEvent.h">
      <Filter>Header FilesFilter>
    ClInclude>
    <ClInclude Include="resource.h">
      <Filter>Header FilesFilter>
    ClInclude>
  ItemGroup>
  <ItemGroup>
    <ResourceCompile Include="reCheck.rc">
      <Filter>Resource FilesFilter>
    ResourceCompile>
  ItemGroup>
  <ItemGroup>
    <QtMoc Include="myQTwidget.h">
      <Filter>Header FilesFilter>
    QtMoc>
    <QtMoc Include="myQGraphicsView.h">
      <Filter>Header FilesFilter>
    QtMoc>
    <QtMoc Include="myQGraphicsViewB.h">
      <Filter>Header FilesFilter>
    QtMoc>
    <QtMoc Include="myStaticalTable.h">
      <Filter>Header FilesFilter>
    QtMoc>
    <QtMoc Include="reCheck.h">
      <Filter>Header FilesFilter>
    QtMoc>
  ItemGroup>
  <ItemGroup>
    <QtRcc Include="reCheck.qrc">
      <Filter>Resource FilesFilter>
    QtRcc>
    <QtRcc Include="Res.qrc">
      <Filter>Resource FilesFilter>
    QtRcc>
  ItemGroup>
  <ItemGroup>
    <QtUic Include="myQTgraphicsView.ui">
      <Filter>Form FilesFilter>
    QtUic>
    <QtUic Include="myQTwidget.ui">
      <Filter>Form FilesFilter>
    QtUic>
    <QtUic Include="myStaticalTable.ui">
      <Filter>Form FilesFilter>
    QtUic>
    <QtUic Include="reCheck.ui">
      <Filter>Form FilesFilter>
    QtUic>
  ItemGroup>
  <ItemGroup>
    <None Include="cpp.hint" />
  ItemGroup>
Project>

你会发现多了很多的刚才选中的.ui、.h、.cpp都添加到里面了，完成。
灾后重建工作圆满完成！！！！
