Question

我正在使用sharepoint 2010，我要做的是采用word文档模板，对几个关键词进行替换（例如：将##ClientID##替换为客户端的id）并保存在sharepoint上的库中具有特定名称。

我已经想出如何在具有word interop的本地计算机上执行此操作，但是interop库这个词并非旨在作为服务运行。然后我发现Word Automation Services似乎做了我需要做的事情。但是，我在互联网上找到的每个例子（包括这里的SO）都只是“如何使用Microsoft.Office.Word.Server.Conversions命名空间从word文档转换为xxx”。我还没有找到关于如何使用Microsoft.Office.Word.Server.Service命名空间对文档进行查找和替换的示例。 MSDN非常缺乏如何使用这些类，我不知道从哪里开始使用它。

是不是可以使用这些服务来做我想做的事情？如果可以做到，有人能指出我正确的方向去做我想做的事吗？

Answer 1

Word Automation Services似乎不是我想用来做我想做的事情，我需要的是Open XML SDK。

更新：这里是关于如何对文档进行替换的代码，在我的文本中我想替换富文本框中的位置。所以这就是我在SdtRun里面看的原因。

public FileDetails GetOrGenerateChecklist(string PracticeName, string ContractID, string EducationDate, string MainContactInfo, string Address)
{
    if (String.IsNullOrEmpty(PracticeName) || String.IsNullOrEmpty(ContractID))
        return null;
    SPWeb web = SPContext.Current.Web;

    SPDocumentLibrary list = (SPDocumentLibrary)web.Lists["Educator Checklists"];
    var templetAddr = String.Concat(web.Url, '/', list.DocumentTemplateUrl);
    SPQuery query = new SPQuery();
    query.Query = string.Concat(
                            "<Where><Eq>",
                                "<FieldRef Name='FileLeafRef'/>",
                                "<Value Type='File'>", PracticeName, " - ", ContractID, ".docx</Value>",
                            "</Eq></Where>");
    var items = list.GetItems(query);

    //if document exists return existing document.
    if (items.Count > 0)
        return new FileDetails() { Address = String.Concat(web.Url, "/Educator Checklists/", PracticeName, " - ", ContractID, ".docx"), LastModified = (DateTime)items[0]["Modified"]};

    //Begin transforming form template to document.
    MemoryStream documentStream;

    //copy the stream to memory
    using (Stream tplStream = web.GetFile(templetAddr).OpenBinaryStream())
    {
        documentStream = new MemoryStream((int)tplStream.Length);
        CopyStream(tplStream, documentStream);
        documentStream.Position = 0L;
    }

    using (WordprocessingDocument template = WordprocessingDocument.Open(documentStream, true))
    {
        template.ChangeDocumentType(DocumentFormat.OpenXml.WordprocessingDocumentType.Document);
        MainDocumentPart mainPart = template.MainDocumentPart;
        mainPart.DocumentSettingsPart.AddExternalRelationship(
            "http://schemas.openxmlformats.org/officeDocument/2006/relationships/attachedTemplate",
            new Uri(templetAddr, UriKind.Absolute));

        ReplaceText(mainPart, "#PracticeName#", PracticeName);
        if(!String.IsNullOrEmpty(EducationDate))
            ReplaceText(mainPart, "#EducationDate#", EducationDate);
        if(!String.IsNullOrEmpty(MainContactInfo))
            ReplaceText(mainPart, "#MainContactInfo#", MainContactInfo);
        if(!String.IsNullOrEmpty(Address))
            ReplaceText(mainPart, "#Address#", Address);
    }
    documentStream.Position = 0L;
    try
    {
        list.RootFolder.Files.Add(String.Concat(PracticeName, " - ", ContractID, ".docx"), documentStream);
    }
    catch(SPException)
    {
        return null;
    }

    return new FileDetails() { Address = String.Concat(web.Url, "/Educator Checklists/", PracticeName, " - ", ContractID, ".docx"), LastModified = DateTime.Now };


}

private static void CopyStream(Stream source, Stream destination, int bufferSize = 0x1000)
{
    int num;
    byte[] buffer = new byte[bufferSize];
    while ((num = source.Read(buffer, 0, buffer.Length)) != 0)
    {
        destination.Write(buffer, 0, num);
    }

}

private static void ReplaceText(MainDocumentPart docPart, string match, string value)
{
    if (value == null)
        value = String.Empty;
    var sdtr = docPart.Document.Descendants<SdtRun>();
    foreach (var sdt in sdtr)
    {
        if (sdt.InnerText == match)
        {

            Text txt = new Text(value);
            //using the sdt.FirstChild.FirstChild.CloneNode(true) will copy the text formatting of the old text.
            var newtext = new SdtContentRun(new Run(sdt.FirstChild.FirstChild.CloneNode(true), txt));
            sdt.SdtContentRun.RemoveAllChildren();
            sdt.SdtContentRun.InsertAt(newtext, 0);
        }
    }
}
