Change the ProductName, version, revision by code

Noah Aas 1,210

Hello,

Assembly thisAssem = typeof(TestVersion).Assembly;
AssemblyName thisAssemName = thisAssem.GetName();

Version ver = thisAssemName.Version;

thisAssemName.Name = thisAssemName.Name + ", " + revision;

Console.WriteLine("This is version {0} of {1}.", ver, thisAssemName.Name);

I would like to give my test DLL its own revision. Is it possible to do this via the code?

Or only via Reflection Assembly?

Hi @Noah Aas , Welcome to Microsoft Q&A,

The assembly's version information (AssemblyVersion, 'AssemblyFileAssemblyFileVersion, etc.) is set at compile time via 'AssemblyInfo.csAssemblyInfo.cs or .csproj files and embedded in the DLL or EXE file. This information is part of the assembly's metadata and is static and can only be set at compile time. Therefore, you cannot dynamically change the revision for a test DLL directly through code. This information is read-only and reflection can only read but not modify it.

You can set them in 'AssemblyInfo.cs.

[assembly: AssemblyVersion("1.0.0.*")]
[assembly: AssemblyFileVersion("1.0.0.1234")]
[assembly: AssemblyProduct("YourProductName")]

Best Regards,

That works so far, how could I now bring the revision into my assembly? The end customer does not have the path, how could this be solved elegantly?

The idea is to take this code, if file exists, then read the revision and assign it. Do you have any tips on finding a solution? How do the experts do it?

Assembly executingAssembly;
AssemblyName executingAssemblyName;
Version executingAssemblyVersion;
executingAssembly = Assembly.GetEntryAssembly();
executingAssemblyName = executingAssembly.GetName();
executingAssemblyVersion = executingAssemblyName.Version;
string assemblyVersion = executingAssemblyVersion.ToString(4);

path = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);
var descriptionAttribute = executingAssembly.GetCustomAttribute<AssemblyDescriptionAttribute>();
var titleAttribute = executingAssembly.GetCustomAttribute<AssemblyTitleAttribute>();



public class SvnInfoFetcher
   {
       public static void GetSvnInfo(string workingDirectory)
       {
           // Create a new process to run the svn info command
           Process svnProcess = new Process
           {
               StartInfo = new ProcessStartInfo
               {
                   FileName = "svn",
                   Arguments = "info",
                   RedirectStandardOutput = true,
                   UseShellExecute = false,
                   CreateNoWindow = true,
                   WorkingDirectory = workingDirectory // Set the working directory to your SVN directory
               }
           };

           // Start the process and read the output
           svnProcess.Start();
           string output = svnProcess.StandardOutput.ReadToEnd();
           svnProcess.WaitForExit();

           // Parse the output for the required information
           ParseSvnInfo(output);
       }

       private static void ParseSvnInfo(string svnInfoOutput)
       {
           string revision = "";
           string date = "";
           string lastChangedAuthor = "";
           string lastChangedRev = "";
           string lastChangedDate = "";

           // Split the output by line
           string[] lines = svnInfoOutput.Split(new[] { Environment.NewLine }, StringSplitOptions.None);

           foreach (string line in lines)
           {
               if (line.StartsWith("Revision:"))
               {
                   revision = line.Substring("Revision:".Length).Trim();
               }
               else if (line.StartsWith("Last Changed Author:"))
               {
                   lastChangedAuthor = line.Substring("Last Changed Author:".Length).Trim();
               }
               else if (line.StartsWith("Last Changed Rev:"))
               {
                   lastChangedRev = line.Substring("Last Changed Rev:".Length).Trim();
               }
               else if (line.StartsWith("Last Changed Date:"))
               {
                   lastChangedDate = line.Substring("Last Changed Date:".Length).Trim();
               }
           }

           // Log or display the information
           Console.WriteLine($"Revision: {revision}");
           Console.WriteLine($"Last Changed Author: {lastChangedAuthor}");
           Console.WriteLine($"Last Changed Rev: {lastChangedRev}");
           Console.WriteLine($"Last Changed Date: {lastChangedDate}");
       }
   }

   class Program
   {
       static void Main()
       {
           string workingDirectory = @"C:\Path\To\Your\SVN\Working\Copy";
           SvnInfoFetcher.GetSvnInfo(workingDirectory);
       }
   }

You can store SVN revisions in embedded resources of your application. After getting the revision information through SvnInfoFetcher, generate a JSON file or text file and embed it in the assembly resource. Then load the resource at runtime.

Steps: Use SvnInfoFetcher to write the revision to a text file, such as revision.txt.

In the project file .csproj, set the file as an embedded resource:

<ItemGroup> <EmbeddedResource Include="revision.txt" /> </ItemGroup>

Read the content in the embedded resource:

using System.Reflection; using System.IO; public static string GetEmbeddedRevision() { var assembly = Assembly.GetExecutingAssembly(); using (Stream stream = assembly.GetManifestResourceStream("YourNamespace.revision.txt")) using (StreamReader reader = new StreamReader(stream)) { return reader.ReadToEnd().Trim(); } } Console.WriteLine($"Revision: {GetEmbeddedRevision()}");
