推荐答案

简单的原因是Word和PDF文件不仅仅包含.TXT文件那样的文本，它们还包含一个许多其他信息(对于Word文档而言)可能不包含太多(如果有的话)可读文本，具体取决于创建它们的Word版本.

如果您需要获取使用特定应用程序创建的文档的字数统计，则yoiu要么需要使用该应用程序打开它，要么编写/查找一个合适的阅读器插件来帮助您.恐怕仅以文本和阅读行的形式打开文件根本无法完成工作.

The simple reason is that Word and PDF files doe not just contain the text in the way that a .TXT file does - they contain a lot of other information, and in the case of word documents, may not contain much if any readable text depending on teh version of Word that they were created with.

If you need to get the word count for a document created with a specific application, then yoiu either need to open it with that application, or write / find an appropriate reader add-in that can do it for you. Just opening the file as text and reading lines will not do the job at all, I''m afraid.

要将上传的文件保存在默认位置，您必须明确指定文件路径为在下面.

To save a uploaded file in default location you have to give file path explicitly as below.

FileUpload.SaveAs(filepath);

//[文件路径包含您的默认文件路径]

要不计算单词数，请参考以下代码...这可能会有所帮助..code在c#中...

//[file path contains your default file path]

To count no of words refer the following code...it may help..code is in c# ...

StreamReader sr=new StreamReader(filepath);

String all=sr.ReadToEnd();

sr.Close();

char[] chararray = {' ' , ',' , '\n' , '\t' , '\f'};

//  [put all possible chars which all are used to separate a word in this char array]

String[] strarray = all.Split(chararray);

int wordcount = strarray.Length;

wordcount中没有单词...

但是，据我所知，excel，pdf，powerpoint文档都包含一些额外的char和定界符以及其他基于其格式的特殊char ...

使用上面的代码可以轻松读取txt和rtf文件.

wordcount contains no of words...

But up to my Knowledge word,excel,pdf ,power point documents are contains some extra char and delimiters and other special char based on their format...

txt and rtf file can be readed easily using above code.
