I did this with the version number and application name. The following works in Play

阅读更多关于 Which version of C# am I using

My question is as easy as it seems: I want to find out which version of C# I'm using. If I would be using python I would do something like python -V from command line, or type import sys print sys.version In php I would do something like this: phpinfo(); in java: java -version But I was not able to find how to achieve this in C#. I'm completely new to C#, so please do not beat me too hard. What surprises me that I was not able to find this answer on SO, therefore I think that I'm missing something or bad in finding things. BTW, this question does not answer it, although the name suggests that

What is the simplest way to retrieve version number from maven's pom.xml in code, i.e., programatically? Alex Miller Assuming you're using Java, you can Create a .properties file in (most commonly) your src/main/resources directory (but in step 4 you could tell it to look elsewhere). Set the value of some property in your .properties file using the standard Maven property for project version: foo.bar=${project.version} In your Java code, load the value from the properties file as a resource from the classpath (google for copious examples of how to do this, but here's an example for starters ).

How do I programmatically get the version of a DLL or EXE file?

阅读更多关于 How do I programmatically get the version of a DLL or EXE file?

I need to get the product version and file version for a DLL or EXE file using Win32 native APIs in C or C++. I'm not looking for the Windows version, but the version numbers that you see by right-clicking on a DLL file, selecting "Properties", then looking at the "Details" tab. This is usually a four-part dotted version number x.x.x.x. You would use the GetFileVersionInfo API. See Using Version Information on the MSDN site. Sample: DWORD verHandle = 0; UINT size = 0; LPBYTE lpBuffer = NULL; DWORD verSize = GetFileVersionInfoSize( szVersionFile, &verHandle); if (verSize != NULL) { LPSTR

How do I detect at runtime that .NET version 4.5 is currently running your code?

阅读更多关于 How do I detect at runtime that .NET version 4.5 is currently running your code?

I installed .NET 4.5 Developer preview from http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=27541 , which 'replaces' .NET 4.0 version. However, the old way to detect the .NET framework version seems to return 4.0 (more precisely 4.0.30319.17020 on my PC), instead of 4.5 (sure probably for backward compatibility, or?): using System; namespace ConsoleApplication { class Program { static void Main(string[] args) { var version = Environment.Version; Console.WriteLine(version.ToString()); Console.ReadKey(); } } } How do I detect that my code is really executed by .NET 4.5?

How can I get the assembly file version

阅读更多关于 How can I get the assembly file version

In AssemblyInfo there are two assembly versions: 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.

I can get the Assembly Version with the following line of code: Version version = Assembly.GetEntryAssembly().GetName().Version; But how can I get the Assembly File Version ?
