小技巧，使用低版本的VS打开高版本的解决方案（使用VS2008打开VS2010的解决方案--同样适用于其他版本）

今天某童鞋想打开老师给的一个VS2010的工程，而其电脑上却没有装VS2010，只装了VS2008，

我让其将工程发给我，我的机子也只装了VS2008，打开工程时提示如下:

选择的文件是解决方案文件，但是用此应用程序的较新版本创建的，无法打开。//截图如下





看后，我突发灵感，将该工程的解决方案文件的后缀由xxx.sln改成了xxx.txt然后，查看其内容如下:

Microsoft Visual Studio Solution File, Format Version 11.00

# Visual Studio 2010

Project("{8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942}") = "FishGame_SXYN", "FishGame.vcxproj", "{8783BEA9-9205-451D-8060-27FCB61620F4}"

EndProject

Global

GlobalSection(SolutionConfigurationPlatforms) = preSolution

Debug_Unicode|Win32 = Debug_Unicode|Win32

Debug|Win32 = Debug|Win32

Release_Unicode|Win32 = Release_Unicode|Win32

Release|Win32 = Release|Win32

EndGlobalSection

GlobalSection(ProjectConfigurationPlatforms) = postSolution

{8783BEA9-9205-451D-8060-27FCB61620F4}.Debug_Unicode|Win32.ActiveCfg = Debug_Unicode|Win32

{8783BEA9-9205-451D-8060-27FCB61620F4}.Debug_Unicode|Win32.Build.0 = Debug_Unicode|Win32

{8783BEA9-9205-451D-8060-27FCB61620F4}.Debug|Win32.ActiveCfg = Debug|Win32

{8783BEA9-9205-451D-8060-27FCB61620F4}.Debug|Win32.Build.0 = Debug|Win32

EndGlobalSection

GlobalSection(SolutionProperties) = preSolution

HideSolutionNode = FALSE

EndGlobalSection

EndGlobal

很明显在上面我们看到了# Visual Studio 2010，于是我赶紧将其该成了# Visual Studio 2008，再次打开工程时，

发现还是打不开，想了下，我将自己的VS2008工程的YYY.sln改成YYY.txt,然后看其内容如下:

Microsoft Visual Studio Solution File, Format Version 10.00

# Visual Studio 2008

Project("{8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942}") = "FishGame_SXYN", "FishGame.vcproj", "{8783BEA9-9205-451D-8060-27FCB61620F4}"

EndProject

Global

GlobalSection(SolutionConfigurationPlatforms) = preSolution

Debug_Unicode|Win32 = Debug_Unicode|Win32

Debug|Win32 = Debug|Win32

Release_Unicode|Win32 = Release_Unicode|Win32

Release|Win32 = Release|Win32

EndGlobalSection

GlobalSection(ProjectConfigurationPlatforms) = postSolution

{8783BEA9-9205-451D-8060-27FCB61620F4}.Debug_Unicode|Win32.ActiveCfg = Debug_Unicode|Win32

{8783BEA9-9205-451D-8060-27FCB61620F4}.Debug_Unicode|Win32.Build.0 = Debug_Unicode|Win32

{8783BEA9-9205-451D-8060-27FCB61620F4}.Debug|Win32.ActiveCfg = Debug|Win32

{8783BEA9-9205-451D-8060-27FCB61620F4}.Debug|Win32.Build.0 = Debug|Win32

{8783BEA9-9205-451D-8060-27FCB61620F4}.Release_Unicode|Win32.ActiveCfg = Release_Unicode|Win32

{8783BEA9-9205-451D-8060-27FCB61620F4}.Release_Unicode|Win32.Build.0 = Release_Unicode|Win32

{8783BEA9-9205-451D-8060-27FCB61620F4}.Release|Win32.ActiveCfg = Release|Win32

{8783BEA9-9205-451D-8060-27FCB61620F4}.Release|Win32.Build.0 = Release|Win32

EndGlobalSection

GlobalSection(SolutionProperties) = preSolution

HideSolutionNode = FALSE

EndGlobalSection

EndGlobal

对比一下VS2010的工程，

VS2010的前三行为：

Microsoft Visual Studio Solution File, Format Version 11.00

# Visual Studio 2010

Project("{8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942}") = "FishGame_SXYN",
"FishGame.vcxproj",
"{8783BEA9-9205-451D-8060-27FCB61620F4}"

VS2008的前三行为：

Microsoft Visual Studio Solution File, Format Version 10.00

# Visual Studio
2008

Project("{8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942}") = "FishGame_SXYN", "FishGame.vcproj",
"{8783BEA9-9205-451D-8060-27FCB61620F4}"

很明显了，

现在我们将VS2010工程xxx.txt的前三行改为VS2008工程的YYY.txt前三行即可。

最后将xxx.txt 改回xxx.sln，在用VS2008打开xxx.sln，已经可以打开了哦。
