如何尋找 檔案的MIME類型

通過尋找註冊表

HKEY_CLASSES_ROOT\MIME\Database\Content Type

word的mime是application/msword

直接開啟檔案在網頁中

Response.Buffer = true;

Response.ContentType = "application/vnd.ms-excel";

byte[] buffer = new byte[1024];

FileStream fs = new FileStream(@"C:\test.xls",FileMode.Open,FileAccess.Read);

try

{

 int i = buffer.Length;

 while(i == buffer.Length)

 {

  i = fs.Read(buffer,0,buffer.Length);

  Response.OutputStream.Write(buffer,0,i);

 }

}

finally

{

 fs.Close();

}

Response.Flush();
