C# Class HttpMultipartParser.StreamingMultipartFormDataParser

Provides methods to parse a multipart/form-data stream into it's parameters and file data.

A parameter is defined as any non-file data passed in the multipart stream. For example any form fields would be considered a parameter.

The parser determines if a section is a file or not based on the presence or absence of the filename argument for the Content-Type header. If filename is set then the section is assumed to be a file, otherwise it is assumed to be parameter data.

Public Methods

Method	Description
Run ( ) : void	Begins executing the parser. This should be called after all handlers have been set.
StreamingMultipartFormDataParser ( Stream stream ) : System	Initializes a new instance of the StreamingMultipartFormDataParser class with an input stream. Boundary will be automatically detected based on the first line of input.
StreamingMultipartFormDataParser ( Stream stream, Encoding encoding ) : System	Initializes a new instance of the StreamingMultipartFormDataParser class with the input stream and stream encoding. Boundary is automatically detected.
StreamingMultipartFormDataParser ( Stream stream, Encoding encoding, int binaryBufferSize ) : System	Initializes a new instance of the StreamingMultipartFormDataParser class with the stream, input encoding and buffer size. Boundary is automatically detected.
StreamingMultipartFormDataParser ( Stream stream, string boundary ) : System	Initializes a new instance of the StreamingMultipartFormDataParser class with the boundary and input stream.
StreamingMultipartFormDataParser ( Stream stream, string boundary, Encoding encoding ) : System	Initializes a new instance of the StreamingMultipartFormDataParser class with the boundary, input stream and stream encoding.
StreamingMultipartFormDataParser ( Stream stream, string boundary, Encoding encoding, int binaryBufferSize ) : System	Initializes a new instance of the StreamingMultipartFormDataParser class with the boundary, stream, input encoding and buffer size.

Private Methods

Method	Description
CalculateNewlineLength ( byte &data, int offset ) : int	Calculates the length of the next found newline. data[offset] is the start of the space to search.
DetectBoundary ( RebufferableBinaryReader reader ) : string	Detects the boundary from the input stream. Assumes that the current position of the reader is the start of the file and therefore the beginning of the boundary.
FindNextNewline ( byte &data, int offset, int maxBytes ) : int	Finds the next sequence of newlines in the input stream.
Parse ( RebufferableBinaryReader reader ) : void	Begins the parsing of the stream into objects.
ParseFilePart ( string>.Dictionary parameters, RebufferableBinaryReader reader ) : void	Parses a section of the stream that is known to be file data.
ParseParameterPart ( string>.Dictionary parameters, RebufferableBinaryReader reader ) : void	Parses a section of the stream that is known to be parameter data.
ParseSection ( RebufferableBinaryReader reader ) : void	Parses the header of the next section of the multipart stream and determines if it contains file data or parameter data.
SplitBySemicolonIgnoringSemicolonsInQuotes ( string line ) : IEnumerable	Splits a line by semicolons but ignores semicolons in quotes.

Method Details

Run() public method

Begins executing the parser. This should be called after all handlers have been set.

public Run ( ) : void
return	void

StreamingMultipartFormDataParser() public method
