SVN API with C# - Browse Files in SVN

TortoiseProc.exe /command:repo browser /path:” SVNPATH” /outfile:” path\to\file”

In the preceding command, we have the following three parameters.

• /command: repo browser: Starts the repository browser dialog, pointing to the URL of the working copy given in /path or /path that points directly to an URL.
• /path:” SVNPATH”: Here, we should provide the SVN path to be opened. The path should be enclosed in double quotes, and there is no space between the /path: and “SVNPATH”.
• /out file:”path\to\file”: Once the repo browser is opened, we will be selecting the file or folder from the browser. After selecting the file, the selected URL and revision are written to that file when the repository browser is closed. The first line in that text file contains the URL, and the second line is the revision in text format. The path should be enclosed in double quotes, and there is no space between the /out file: and ”path\to\file”.

So finally, the selected file path from the SVN repo browser is stored in the output file path.

SVN Browsing using C#

Now, we have the command to be executed from the command prompt. The same command can also be executed from .NET using the following code.

using System;
using System.Diagnostics;
class Program
{
    private void ExecuteSVNCommand(string SVNCommand)
    {
        try
        {
            ProcessStartInfo processStartInfo = new ProcessStartInfo();
            processStartInfo.WorkingDirectory = @"C:\Program Files\TortoiseSVN\bin";
            processStartInfo.RedirectStandardInput = true;
            processStartInfo.CreateNoWindow = true;
            processStartInfo.WindowStyle = ProcessWindowStyle.Hidden;
            processStartInfo.FileName = "cmd.exe";
            processStartInfo.UseShellExecute = false;
            processStartInfo.Arguments = SVNCommand;
            Process process = Process.Start(processStartInfo);
            process.WaitForExit();
            int exitCode = process.ExitCode;
            if (exitCode == 0)
            {
                // Success
            }
            else
            {
                // Failed
            }
        }
        catch (Exception ex)
        {
            // Catch Exception
        }
    }
    static void Main(string[] args)
    {
        // Your code here
    }
}

Note. If we pass the preceding command to this method, it will exit with the exit code of 1 and it will throw an exception of type “System.InvalidOperationException”. So the command to be passed is.

string command = @"/c " + "TortoiseProc.exe /command:repobrowser /path:" + SVNURL + " /outfile:" + OUTPUT_PATH;

Here “/c” tells cmd that we want it to execute the command that follows and then terminate.

I have used the OUTPUT_PATH file path extension as .xls so that the first cell will hold the selected URL of SVN, and the second cell will hold the revision in text format. You can provide “.txt” as well.
