The ReadAllText method of the My.Computer.FileSystem
object allows you to read from a text file. The file encoding can be specified if the contents of the file use an encoding such as ASCII or UTF-8.
ASP.NET script is the simple text file with ASP.NET source code. ASPX file cannot be simply converted to another format, but it can be edited in any text editor or word processor. Find conversions from aspx file: aspx to docx.

If you are reading from a file with extended characters, you will need to specify the file encoding.
Note
- I know I can save the aspx document as PDF on the C drive, double-click that PDF document to launch Adobe Acrobat Reader, but that is two-step process. So far, I have set associated PDF with Adobe Acrobat Reader and went into Firefox Tools/Add-ins/Plugins/ and changed Adobe Acrobat to 'Always Active', but to no avail.
- Choose a document or an image and then click the 'View File' button. The viewer supports various types of documents and images: word, powerpoint, pdf, open office documents, djvu, ps, jpeg 2000, png, psd, tiff, and many others. See supported file types.
- Upload and view your local files or remote documents using Ajax, jQuery, HTML 5 and CSS 3. Share Your Documents Send your document links to friends or colleagues.
To read a file a single line of text at a time, use the OpenTextFileReader method of the My.Computer.FileSystem
object. The OpenTextFileReader
method returns a StreamReader object. You can use the ReadLine method of the StreamReader
object to read a file one line at a time. You can test for the end of the file using the EndOfStream method of the StreamReader
object.
To read from a text file
Use the ReadAllText
method of the My.Computer.FileSystem
object to read the contents of a text file into a string, supplying the path. The following example reads the contents of test.txt into a string and then displays it in a message box.
To read from a text file that is encoded
Use the ReadAllText
method of the My.Computer.FileSystem
object to read the contents of a text file into a string, supplying the path and file encoding type. The following example reads the contents of the UTF32 file test.txt into a string and then displays it in a message box.

The following conditions may cause an exception:
The path is not valid for one of the following reasons: it is a zero-length string, it contains only white space, it contains invalid characters, or it is a device path (ArgumentException).
The path is not valid because it is
Nothing
(ArgumentNullException).The file does not exist (FileNotFoundException).
The file is in use by another process or an I/O error occurs (IOException).
The path exceeds the system-defined maximum length (PathTooLongException).
A file or directory name in the path contains a colon (:) or is in an invalid format (NotSupportedException).
There is not enough memory to write the string to buffer (OutOfMemoryException).
The user lacks necessary permissions to view the path (SecurityException).
Do not make decisions about the contents of the file based on the name of the file. For example, the file Form1.vb may not be a Visual Basic source file.
Verify all inputs before using the data in your application. The contents of the file may not be what is expected, and methods to read from the file may fail.
