Question

我的情况是，用户可以上传包含某些属性占位符的word文档（例如，在MS Word中，用户已经转到插入＆gt;快速部件＆gt;文档属性并选择了属性）。我要支持的具体属性是Title，Author，Company和Publish Date。

Title和Author设置为包属性，Company设置为扩展文件属性。这些是使用以下代码设置的，它可以正常工作：

private static void SetDocumentProperties(ReportTemplateModel model, WordprocessingDocument wordDocument)
{
    //these properties always exist
    wordDocument.PackageProperties.Title = model.Title;
    wordDocument.PackageProperties.Creator = model.Author;
    wordDocument.PackageProperties.Created = DateTime.Now;
    wordDocument.PackageProperties.Modified = DateTime.Now;

    //these properties can be null
    if (wordDocument.ExtendedFilePropertiesPart == null)
    {
        wordDocument.AddNewPart<ExtendedFilePropertiesPart>();
    }
    if (wordDocument.ExtendedFilePropertiesPart.Properties == null)
    {
        wordDocument.ExtendedFilePropertiesPart.Properties = new Properties(new Company(model.SiteName));
    }
    else
    {
        wordDocument.ExtendedFilePropertiesPart.Properties.Company = new Company(model.SiteName);
    }
}

我的问题是，我无法弄清楚如何设置Publish Date属性。我尝试使用下面的代码（改编自https://www.snip2code.com/Snippet/292005/WDSetCustomProperty）将其添加为自定义文件属性，但这不起作用。我已经阅读了一些关于设置自定义属性的内容，但我对它们的工作方式感到困惑。我还不确定Publish Date是否应该实际设置为自定义属性或其他类型的属性。

var customProps = wordDocument.CustomFilePropertiesPart;
if (customProps == null)
{
    customProps = wordDocument.AddCustomFilePropertiesPart();
    customProps.Properties = new DocumentFormat.OpenXml.CustomProperties.Properties();
}
var properties1 = new DocumentFormat.OpenXml.CustomProperties.Properties();

//I have tried both of these lines, neither worked.
//properties1.AddNamespaceDeclaration("op", "http://schemas.openxmlformats.org/officeDocument/2006/custom-properties");
properties1.AddNamespaceDeclaration("vt", "http://schemas.openxmlformats.org/officeDocument/2006/docPropsVTypes");

var customDocumentProperty1 = new DocumentFormat.OpenXml.CustomProperties.CustomDocumentProperty()
{
    FormatId = "{D5CDD505-2E9C-101B-9397-08002B2CF9AE}",
    PropertyId = 2,
    Name = "Publish Date"
};

customDocumentProperty1.Append(new DocumentFormat.OpenXml.VariantTypes.VTLPWSTR { Text = DateTime.Today.ToShortDateString() });

properties1.Append(customDocumentProperty1);

part.Properties = properties1;

将Publish Date设置为什么类型的属性，以及设置此属性的正确语法是什么？

更新：我发现Publish Date是一个CoverPageProperty，可以使用下面的代码段创建，但我仍然无法找到如何设置它正确地在文件中。

var coverPageProps = new DocumentFormat.OpenXml.Office.CoverPageProps.CoverPageProperties
{
    PublishDate = new PublishDate(DateTime.Today.ToShortDateString())
};

将以下代码添加到我的SetDocumentProperties方法似乎可行。我必须承认我不完全理解下面的代码，所以任何解释仍然是受欢迎的。另外，如果有人的解决方案不包括在C＃中将XML写为字符串，我宁愿避免这种情况。

public void addStudent(ActionRequest actionRequest,
            ActionResponse actionResponse) throws IOException, PortletException,SystemException {
        try {
            System.out.println("Student : "+StudentLocalServiceUtil.getStudentByGenderMale());
            String firstName = ParamUtil.getString(actionRequest, "firstName");
            String lastName = ParamUtil.getString(actionRequest, "lastName");
            int studentAge = ParamUtil.getInteger(actionRequest, "studentAge");
            int studentGender = ParamUtil.getInteger(actionRequest, "sex", 1);
            String address = ParamUtil.getString(actionRequest, "address");
            String teacherName=(String) actionRequest.getParameter("teacher");
            System.out.println("teacher name " + teacherName);
            // add student record
            // create primary key
            long studentId = CounterLocalServiceUtil.increment();
            // create student persistance object
            Student student = null;
            student = StudentLocalServiceUtil.createStudent(studentId);
            // fill the data in persistance object
            student.setFirstName(firstName);
            student.setLastName(lastName);
            student.setStudentAge(studentAge);
            student.setStudentGender(studentGender);
            student.setStudentAddress(address);
            // Add student persistance object to database student table
            student = StudentLocalServiceUtil.addStudent(student);
            if (student != null) {
                // adding success message
                SessionMessages.add(actionRequest.getPortletSession(),
                        "student-add-success");
                _log.info("Student have been added successfylly");
            } else {
                SessionErrors.add(actionRequest.getPortletSession(),
                        "student-add-error");
                _log.error("There is an Erron in adding Student");
            }
            // navigate to add student jsp page
            actionResponse.setRenderParameter("mvcPath",
                    "/html/jsps/add_student.jsp");
        } catch (Exception e) {
            SessionErrors.add(actionRequest.getPortletSession(),
                    "student-add-error");
            e.printStackTrace();
        }
    }
