You could use the /compact command line argument for msaccess.exe or you can use interop and do something like this Compact And Repair that I found on code project.

C# sample using MS Access Command Line…

var mdbFileName = Path.GetFullPath("youraccessdb.mdb");
if (!File.Exists(mdbFileName))
    throw new FileNotFoundException(
        "Could not find Access Database",
        mdbFileName);

var programFiles = Environment.GetEnvironmentVariable("ProgramFiles");
var accessPath = Path.Combine(
                    programFiles,
                    @"Microsoft Office\Office12\MSACCESS.EXE");

if (!File.Exists(accessPath))
    throw new FileNotFoundException(
        "Could not find MSACCESS.EXE",
        accessPath);

var commandArgs = string.Format("/compact \"{0}\"", mdbFileName);

var process = Process.Start(accessPath, commandArgs);
process.WaitForExit();

if (process.ExitCode != 0)
    throw new ApplicationException(string.Format(
        "Access Exited with Error Code [{0}]",
        process.ExitCode));
