是否有可能重新命名Outlook类别的编程方式?

StackOverflow https://stackoverflow.com/questions/2007136

题

我们发展中Outlook2007年增加。用于测试outlook类别重新命名我已经加入以下代码块

 var session = Application.Session;
 var categories = session.Categories;
 var category1 = session.Categories[1];

 //catefory1.Name is "Group1" before executing line below
 category1.Name = "TEST!!!";

 Marshal.ReleaseComObject(category1);
 Marshal.ReleaseComObject(categories);
 Marshal.ReleaseComObject(session);

到底序 private void ThisAddIn_Startup(object sender, EventArgs e) 法。类别重新命名，但如果Outlook是关闭的，上述行的是评论说，与展望再次开始-类别名称不是"试验!!!" 正如我的预期。它是"组1"如之前重新命名。是否有可能重新命名outlook类别"永远"的代码？Microsoft。办公室。互操作。展望。类别没有保存()或更新()或持续存在()方法。

P.S.我们发展中Outlook2007年增加使用Visual Studio2008.净3.5,C#3.问题是再现Outlook2007sp1和SP2。其他outlook版本没有进行测试。

有帮助吗？

我已经解决了这个问题(该问题本身似乎是Outlook2007bug)使用黑客。以下链接帮我创造的哈克(哎呀，没有足够的信誉，以后1个链接):

        public static void RenameCategory(string oldName, string newName, Application outlookApplication)
        {
            MAPIFolder calendarFolder = outlookApplication.Session.GetDefaultFolder(

            if (categoryListStorageItem != null)
            {

                    var xmlBytes = (byte[])categoryListPropertyAccessor.GetProperty(schemaName);

                    // the byte array has to be translated into a string and then the XML has to be parsed
                    var xmlReader = XmlReader.Create(new StringReader(Encoding.UTF8.GetString(xmlBytes)));

                    // xmlWriter will write new category list xml with renamed category
                    XmlWriterSettings settings = new XmlWriterSettings { Indent = true, IndentChars = ("\t") };
                    var stringWriter = new StringWriter();
                    var xmlWriter = XmlWriter.Create(stringWriter, settings);

                    xmlReader.Read(); // read xml declaration
                    xmlWriter.WriteNode(xmlReader, true);
                    xmlReader.Read(); // read categories
                    xmlWriter.WriteStartElement(xmlReader.Name, CategoriesXmlElementNamespace);
                    while (xmlReader.MoveToNextAttribute())
                    {
                        if (xmlReader.Name != XmlNamespaceAttribute) // skip namespace attr
                        {

                        }
                    }
                    while (xmlReader.Read())
                    {
                        switch (xmlReader.NodeType)
                        {
                            case XmlNodeType.Element: // read category
                                xmlWriter.WriteStartElement(CategoryElement);
                                while (xmlReader.MoveToNextAttribute())
                                {
                                    if ((xmlReader.Name == NameAttribute) && (xmlReader.Value == oldName))
                                    {
                                        xmlWriter.WriteAttributeString(NameAttribute, newName);
                                    }
                                    else
                                    {
                                        xmlWriter.WriteAttributeString(xmlReader.Name, xmlReader.Value);
                                    }
                                }
                                xmlWriter.WriteEndElement();
                                break;
                            case XmlNodeType.EndElement: // categories ended
                                xmlWriter.WriteEndElement();
                                break;
                        }
                    }
                    xmlReader.Close();
                    xmlWriter.Close();

                    xmlBytes = Encoding.UTF8.GetBytes(stringWriter.ToString());
                    categoryListPropertyAccessor.SetProperty(schemaName, xmlBytes);
                    categoryListStorageItem.Save();
                }
                catch (OutOfMemoryException)
                {
                    // if error is "out of memory error" then the XML blob was too big
                }
            }
        }
    }
}

此辅助的方法必须以被称为现有类别更名，例如：

 var session = Application.Session;
 var categories = session.Categories;
 var category1 = session.Categories[1];

 //catefory1.Name is "Group1" before executing line below
 OutlookCategoryHelper.RenameCategory(category1.Name, "TEST!!!", Application);
 category1.Name = "TEST!!!";

 Marshal.ReleaseComObject(category1);
 Marshal.ReleaseComObject(categories);
 Marshal.ReleaseComObject(session);

其他提示

这是一个Outlook错误与Outlook 2007 SP2介绍

“请考虑以下情形。您可以运行在Outlook 2007中创建新的类别自定义应用程序。 您运行的应用程序来创建Outlook 2007中一个新的类别。然后，如果你重新启动Outlook 2007，您创建意外删除的类别。安装Februarycumulative更新或SP2后，会出现此问题。“的
