指定的包无效。主要部分不见了
The specified package is invalid. The main part is missing
下面给出了一个合并函数,它旨在合并一个文件夹中的所有 docx 文件并生成合并后的文件。
public void Merge()
{
try
{
string sid = Request.QueryString["studid"];
string stud = sid.ToString();
string ds = HttpContext.Current.Server.MapPath(("~\StudentBinder") + "\Temp4\");
if (Directory.Exists(ds))
{
DirectoryInfo d = new DirectoryInfo(ds);
FileInfo[] Files = d.GetFiles("*" + stud + "*.docx");
// stud added for differentiating b/w users
string[] filepaths = new string[Files.Length];
int index = 0;
foreach (FileInfo file in Files)
{
filepaths[index] = file.Name;
index++;
}
using (WordprocessingDocument myDoc = WordprocessingDocument.Open(Server.MapPath(filepaths[0]), true))
{
for (int i = 1; i < filepaths.Length; i++)
{
MainDocumentPart mainPart = myDoc.MainDocumentPart;
string altChunkId = "AltChunkId" + i.ToString();
AlternativeFormatImportPart chunk = mainPart.AddAlternativeFormatImportPart(AlternativeFormatImportPartType.WordprocessingML, altChunkId);
using (FileStream fileStream = File.Open(@filepaths[i], FileMode.Open))
{
chunk.FeedData(fileStream);
}
AltChunk altChunk = new AltChunk();
altChunk.Id = altChunkId;
mainPart.Document.Body.InsertAfter(altChunk, mainPart.Document.Body.Elements<DocumentFormat.OpenXml.Wordprocessing.Paragraph>().Last());
mainPart.Document.Save();
myDoc.Close();
}
}
}
}
catch (Exception ex)
{
}
}
但是行
using (WordprocessingDocument myDoc = WordprocessingDocument.Open(Server.MapPath(filepaths[0]), true))
引发错误指定的包无效。主要部分不见了。
我不知道那句话出了什么问题。欢迎任何建议。提前致谢。
你可能 Server.MapPath 两次:在开始时
string ds = HttpContext.Current.Server.MapPath(("~\StudentBinder")+"\Temp4\")
并在
行中
using (WordprocessingDocument myDoc = WordprocessingDocument.Open(Server.MapPath(filepaths[0]), true))
您可以将此行重写为
using (WordprocessingDocument myDoc = WordprocessingDocument.Open(filepaths[0], true))
并且您还需要从 file.FullName 填充文件路径数组,而不是 file.Name:
foreach (FileInfo file in Files)
{
filepaths[index] = file.FullName;
index++;
}
