Tortoise SVN revision number inside C# app log file

Question

Hello,
how can I automatically query the current revision from Tortoise Subversion and
log it in my C# app?

Revision, date and comment is best

Do you have any tips?

<PreBuildEvent>
        if exist "C:\Program Files\TortoiseSVN\bin\SubWCRev.exe" 
                 "C:\Program Files\TortoiseSVN\bin\SubWCRev.exe" 
                 "$(ProjectDir)." 
                 "$(ProjectDir)Properties\AssemblyInfo.Base.cs" 
                 "$(ProjectDir)Properties\AssemblyInfo.cs"
</PreBuildEvent>

What I want inside my C# project.

Hello Thomas, You can create class to read svn revision info step by step, Create below class and call method in program file to get latest change done in SVN, Note : Here I have created console application but you 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); } }

To automatically query the current revision from TortoiseSVN and log it in your C# app, you can use the following approach: Use svn Command Line: Run the svn info command to get revision information:svn info --xml Parse XML Output in C#: Execute the command from your C# app and parse the XML output to extract revision, date, and comment. Here's a sample code snippet for executing the command and parsing the XML: using System; using System.Diagnostics; using System.Xml; class Program { static void Main() { // Execute svn info command var process = new Process { StartInfo = new ProcessStartInfo { FileName = "svn", Arguments = "info --xml", RedirectStandardOutput = true, UseShellExecute = false, CreateNoWindow = true } }; process.Start(); // Read the output var output = process.StandardOutput.ReadToEnd(); process.WaitForExit(); // Parse XML var xmlDoc = new XmlDocument(); xmlDoc.LoadXml(output); var revision = xmlDoc.SelectSingleNode("//entry/@revision")?.Value; var date =xmlDoc.SelectSingleNode("//commit/date")?.InnerText; var comment = xmlDoc.SelectSingleNode("//commit/msg")?.InnerText; // Log the information Console.WriteLine($"Revision: {revision}"); Console.WriteLine($"Date: {date}"); Console.WriteLine($"Comment: {comment}"); } } Make sure the svn command-line tool is installed and accessible from your application. Adjust the XML parsing as needed based on your actual output.

Yes. Is it possible for my application to write the revision to the log file without it being installed at the customer? I only want to know the current revision that is installed at the customer. Can you please give me an answer, then we can close the thread. Thanks to all.

Hello, my goal is to see the revision number at the customer, with which revision created. If I have to call a process, this is not possible. I have a project with n files. How can I create and query a branch so that I get all the files to compile? Thanks for tips. Regards
