How can I get the assembly file version
提问by Enyra
In AssemblyInfothere are two assembly versions:
在AssemblyInfo有两个集版本：
AssemblyVersion: Specify the version of the assembly being attributed.AssemblyFileVersion: Instructs a compiler to use a specific version number for the Win32 file version resource. The Win32 file version is not required to be the same as the assembly's version number.
AssemblyVersion: 指定要归因的程序集的版本。AssemblyFileVersion: 指示编译器使用 Win32 文件版本资源的特定版本号。Win32 文件版本不需要与程序集的版本号相同。
I can get the Assembly Versionwith the following line of code:
我可以Assembly Version使用以下代码行获取：
Version version = Assembly.GetEntryAssembly().GetName().Version;
But how can I get the Assembly File Version?
但是我怎样才能得到Assembly File Version？

See my comment above asking for clarification on what you really want. Hopefully this is it:
请参阅我上面的评论，要求澄清您真正想要的东西。希望是这样：
System.Reflection.Assembly assembly = System.Reflection.Assembly.GetExecutingAssembly();
System.Diagnostics.FileVersionInfo fvi = System.Diagnostics.FileVersionInfo.GetVersionInfo(assembly.Location);
string version = fvi.FileVersion;

UPDATE: As mentioned by Richard Grimes in my cited post, @Iain and @Dmitry Lobanov, my answer is right in theory but wrong in practice.
更新：正如 Richard Grimes 在我引用的帖子中提到的，@Iain 和 @Dmitry Lobanov，我的回答在理论上是正确的，但在实践中是错误的。
As I should have remembered from countless books, etc., while one sets these properties using the [assembly: XXXAttribute], they get highHymaned by the compiler and placed into the VERSIONINFOresource.
正如我应该从无数书籍等中记住的那样，当人们使用 设置这些属性时[assembly: XXXAttribute]，它们会被编译器劫持并放入VERSIONINFO资源中。
For the above reason, you need to use the approach in @Xiaofu's answeras the attributes are stripped after the signal has been extracted from them.
由于上述原因，您需要使用@Xiaofu's answer 中的方法，因为在从属性中提取信号后将剥离属性。
public static string GetProductVersion()
{
var attribute = (AssemblyVersionAttribute)Assembly
.GetExecutingAssembly()
.GetCustomAttributes( typeof(AssemblyVersionAttribute), true )
.Single();
return attribute.InformationalVersion;
}
(From http://bytes.com/groups/net/420417-assemblyversionattribute- as noted there, if you're looking for a different attribute, substitute that into the above)
（来自http://bytes.com/groups/net/420417-assemblyversionattribute- 如上所述，如果您正在寻找不同的属性，请将其替换为上述属性）

There are three versions: assembly, file, and product. They are used by different features and take on different default values if you don't explicit specify them.
共有三个版本： 程序集、文件和产品。如果您没有明确指定它们，它们由不同的功能使用并采用不同的默认值。
string assemblyVersion = Assembly.GetExecutingAssembly().GetName().Version.ToString();
string assemblyVersion = Assembly.LoadFile("your assembly file").GetName().Version.ToString();
string fileVersion = FileVersionInfo.GetVersionInfo(Assembly.GetExecutingAssembly().Location).FileVersion;
string productVersion = FileVersionInfo.GetVersionInfo(Assembly.GetExecutingAssembly().Location).ProductVersion;

When I want to access the application file version (what is set in Assembly Information -> File version), say to set a label's text to it on form load to display the version, I have just used
当我想访问应用程序文件版本（在程序集信息 -> 文件版本中设置的内容）时，比如在表单加载时为其设置标签文本以显示版本，我刚刚使用
versionlabel.Text = "Version " + Application.ProductVersion;

Use this:
用这个：
((AssemblyFileVersionAttribute)Attribute.GetCustomAttribute(
Assembly.GetExecutingAssembly(),
typeof(AssemblyFileVersionAttribute), false)
).Version;
Or this:
或这个：
new Version(System.Windows.Forms.Application.ProductVersion);
