Methods

	Name	Description
	Close	Closes the TextReader and releases any system resources associated with the TextReader. (Inherited from TextReader.)
	CreateObjRef	Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
	Dispose	Releases all resources used by the TextReader object. (Inherited from TextReader.)
	Dispose(Boolean)	Releases the unmanaged resources used by the PdfTextReader and optionally releases the managed resources (Overrides TextReaderDispose(Boolean).)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetLifetimeService	Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	InitializeLifetimeService	Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	MemberwiseClone(Boolean)	Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)
	Peek	Reads the next character without changing the state of the reader or the character source. Returns the next available character without actually reading it from the reader. (Overrides TextReaderPeek.)
	Read	Reads the next character from the text reader and advances the character position by one character. (Overrides TextReaderRead.)
	Read(Char, Int32, Int32)	Reads a specified maximum number of characters from the current reader and writes the data to a buffer, beginning at the specified index. (Overrides TextReaderRead(Char, Int32, Int32).)
	ReadAsync	Reads a specified maximum number of characters from the current text reader asynchronously and writes the data to a buffer, beginning at the specified index. (Inherited from TextReader.)
	ReadBlock	Reads a specified maximum number of characters from the current text reader and writes the data to a buffer, beginning at the specified index. (Inherited from TextReader.)
	ReadBlockAsync	Reads a specified maximum number of characters from the current text reader asynchronously and writes the data to a buffer, beginning at the specified index. (Inherited from TextReader.)
	ReadLine	Reads a line of characters from the text reader and returns the data as a string. (Overrides TextReaderReadLine.)
	ReadLineAsync	Reads a line of characters asynchronously and returns the data as a string. (Inherited from TextReader.)
	ReadToEnd	Reads all characters from the current position to the end of the text reader and returns them as one string. (Inherited from TextReader.)
	ReadToEndAsync	Reads all characters from the current position to the end of the text reader asynchronously and returns them as one string. (Inherited from TextReader.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Examples

Using a PdfTextReader (C#)

Copy

public String ReadTextFromPages(Stream s, int pageStart, int pageEnd)
{
    using (PdfTextDocument doc = new PdfTextDocument(s))
    {
        PdfTextReader rdr = doc.GetPdfTextReader(pageStart, pageEnd);
        return rdr.ReadToEnd();
    }
}

Using a PdfTextReader (Visual Basic)

Copy

Public Function ReadTextFromPages(ByVal s As Stream, ByVal pageStart As Integer, ByVal pageEnd As Integer) As String
    Using doc As New PdfTextDocument(s)
        Dim rdr As PdfTextReader = doc.GetPdfTextReader(pageStart, pageEnd)
        Return rdr.ReadToEnd()
    End Using
End Function
