Syntax

public static class CsvAnalyzer

Methods

Analyze(Stream, Char[], Encoding, out Int32, out Char, out Encoding, out Int32, out Int32)

Reads completely through a CSV stream to determine encoding, separator, field count and row count. Uses fallbackEncoding if there is no BOM. Throws DecoderFallbackException if there are invalid characters in the stream. Returns the separator whose average field count is closest to its max field count.

Declaration

public static void Analyze(Stream stream, char[] separators, Encoding fallbackEncoding, out int fieldCount, out char autodetectSeparator, out Encoding autodetectEncoding, out int bomLength, out int rowCount)

Parameters

Type	Name	Description
System.IO.Stream	stream
System.Char[]	separators
System.Text.Encoding	fallbackEncoding
System.Int32	fieldCount
System.Char	autodetectSeparator
System.Text.Encoding	autodetectEncoding
System.Int32	bomLength
System.Int32	rowCount

Analyze(String, Char[], Encoding, out Int32, out Char, out Encoding, out Int32, out Int32)

Reads completely through a CSV input file to determine encoding, separator, field count and row count. Uses fallbackEncoding if there is no BOM. Throws DecoderFallbackException if there are invalid characters in the stream. Returns the separator whose average field count is closest to its max field count.

Declaration

public static void Analyze(string file, char[] separators, Encoding fallbackEncoding, out int fieldCount, out char autodetectSeparator, out Encoding autodetectEncoding, out int bomLength, out int rowCount)

Parameters

Type	Name	Description
System.String	file	The input file csv file to analyze.
System.Char[]	separators	Set of separators to look for.
System.Text.Encoding	fallbackEncoding	Fallback encoding when default is not suitable.
System.Int32	fieldCount	Output value of identified count of fields in this table.
System.Char	autodetectSeparator	Output value of identified value separator.
System.Text.Encoding	autodetectEncoding	Output value of identified encoding.
System.Int32	bomLength	Output value of
System.Int32	rowCount
