使用流讀取word會產生亂碼
HttpPostedFile myFile=this.ContentFile.PostedFile;
System.IO.Stream myStream=myFile.InputStream;
System.IO.StreamReader myStreamReader=
new System.IO.StreamReader(myStream,System.Text.Encoding.GetEncoding("GB2312"));
string myString=myStreamReader.ReadToEnd();
此時myString就成亂碼了
這樣System.IO.StreamReader myStreamReader=
new System.IO.StreamReader(myStream,System.Text.Encoding.Default);
也是亂碼，但是可以正確讀取text文件。
後來根據word可以轉換爲html的思路，想了另外一個辦法，把word上傳到服務器，轉換爲text，然後讀取text。
調試通過的 代碼如下：
//上傳文件
HttpPostedFile ContentFile=this.ContentFile.PostedFile;
string ContentName=System.IO.Path.GetFileName(ContentFile.FileName);
string ContentPath=Request.MapPath("/web/uploadDocs/"+ContentName);
ContentFile.SaveAs(ContentPath);
string NewContentPath=System.IO.Path.ChangeExtension(ContentPath,"txt");
//轉換word爲text
WordXpControl.WordControler UploadWord=new WordXpControl.WordControler();
UploadWord.Open(ContentPath);
UploadWord.SaveAsExportTye(NewContentPath,WordXpControl.WordControler.ExportType.Text);
UploadWord.Quit();
//讀取對應的text文件
System.IO.StreamReader myReader=new System.IO.StreamReader(NewContentPath,System.Text.Encoding.Default);
strContent=myReader.ReadToEnd();
myReader.Close();
strContent=ManageProcess.GetFormatedString(strContent);
//根據需要決定是否刪除上傳的word文件和對應的text文件
if(this.CbIsDelete.Checked)
{
System.IO.File.Delete(ContentPath);
System.IO.File.Delete(NewContentPath);
}
上面的WordXpControl是前不久封裝的對word操作的程序集，方面對word的操作。使用前要引用Microsoft Word 10 Object Library，然後再引用該程序集即可。通過ExportType枚舉可以決定轉換的類型，如：html。也可進行一些其他操作。該程序集核心代碼來自網上，很多功能本人也未嘗使用。
以上代碼都是在vs2003，win2000,officeXp上調試運行，對於其他版本可能有問題。office2000在孟子的網站上有成功例子。注意給asp.net進程指定system權限運行，以免出現權限不夠的異常。
由於這裏不能上傳，最後給出WordXpControl的代碼，編譯以後即可使用：
