Version comments for a Documentum object

Retrieving the version comments of a Documentum SysObject is an easy task:

private static string GetVersionsComment(IDfSysObject dfObj)
{
    StringBuilder sb = new StringBuilder();

    if (dfObj.getVersionLabelCount() > 0)
    {
        for (int i = 0; i < dfObj.getVersionLabelCount(); i++)
        {
            string versionLabel = dfObj.getVersionLabel(i);
            sb.AppendLine(versionLabel);
        }
        sb.AppendLine(dfObj.getLogEntry());
    }
    return sb.ToString().Trim();
}
