I have an old dll that was compiled against the .NET framework and deployed. I am not sure which version of the .NET framework it was compiled against. I am wondering how I can determine which version of the .NET framework this dll was compiled against? I cannot trust the source code because I believe it has been upgraded to Visual Studio 2008 and changed to .NET framework version 3.5.
我有一个旧的dll，它是针对。net框架编译的。我不确定它所编译的。net框架的哪个版本。我想知道如何确定这个dll编译的。net框架的哪个版本?我不能信任这个源代码，因为我相信它已经升级到Visual Studio 2008，并更改为。net framework 3.5版本。

In PowerShell you can use the following to get the target runtime:
在PowerShell中，您可以使用以下命令获取目标运行时:
$path = "C:\Some.dll"
[Reflection.Assembly]::ReflectionOnlyLoadFrom($path).ImageRuntimeVersion
I adapted this to PowerShell from Ben Griswold's answer.
我根据本·格里斯沃尔德(Ben Griswold)的答案改编了PowerShell。
If you want to know the target framework version specified in Visual Studio, use:
如果您想知道Visual Studio中指定的目标框架版本，请使用:
$path = "C:\Some.dll"
[Reflection.Assembly]::ReflectionOnlyLoadFrom($path).CustomAttributes |
Where-Object {$_.AttributeType.Name -eq "TargetFrameworkAttribute" } |
Select-Object -ExpandProperty ConstructorArguments |
Select-Object -ExpandProperty value
You should get something like
你应该得到一些类似的东西。
.NETFramework,Version=v4.5.2

dotPeek is a great (free) tool to show this information.
dotPeek是一个很好的(免费的)工具来显示这些信息。
If you are having a few issues getting hold of Reflector then this is a good alternative.

You can use ILDASM...
您可以使用ILDASM……
ildasm.exe C:\foo.dll /metadata[=MDHEADER] /text /noil
and check for the 'Metadata section' in the output. It would be something like this:
检查输出中的“元数据”部分。大概是这样的:
Metadata section: 0x424a5342, version: 1.1, extra: 0, version len: 12, version: v4.0.30319
元数据部分:0x424a5342，版本:1.1，额外:0，版本len: 12，版本:v4.0.30319。
The 'version' tag will tell you the .NET Framework version. In the above example it is 4.0.30319
“版本”标签会告诉你。net框架版本。在上面的示例中，它是4.0.30319

You have a few options: To get it programmatically, from managed code, use Assembly.ImageRuntimeVersion:
您有几个选项:要以编程方式从托管代码中获得它，请使用Assembly.ImageRuntimeVersion:
Dim a As Assembly = Reflection.Assembly.ReflectionOnlyLoadFrom("C:\path\assembly.dll")
Dim s As String = a.ImageRuntimeVersion
From the command line, starting in v2.0, ildasm.exe will show it if you double-click on "MANIFEST" and look for "Metadata version". Determining an Image’s CLR Version
从命令行开始，从v2.0开始，ildasm。如果双击“MANIFEST”并查找“元数据版本”，exe将显示它。确定图像的CLR版本。

Yet another option via Visual Studio, add a reference to the DLL to any project, then right-clicking on the new reference and click Properties, you can see what you are looking for in Runtime version:
通过Visual Studio的另一个选项，向任何项目添加一个DLL的引用，然后右键单击新的引用并单击Properties，您可以看到在运行时版本中您要查找的内容:

Decompile it with ILDASM, and look at the version of mscorlib that is being referenced (should be pretty much right at the top).
将它与ILDASM进行反编译，并查看正在引用的mscorlib版本(在顶部应该相当正确)。
