Syntax

public class MultiFileTextReader : TextReader, IDisposable

Constructors

MultiFileTextReader(DirectoryInfo, String, Boolean)

Instantiates a MultiFileTextReader which works on the files contained in the specified directory and its subdirectories.

Declaration

public MultiFileTextReader(DirectoryInfo rootDirectory, string fileFilter, bool recurse)

Parameters

Type	Name	Description
System.IO.DirectoryInfo	rootDirectory	The directory in which to search for applicable files.
System.String	fileFilter	If non-null, only files which match the filter are added to the file set (see System.IO.DirectoryInfo.GetFiles()).
System.Boolean	recurse	If true, subdirectories are scanned for matching false. Otherwise, only files in the specified root directory are considered.

MultiFileTextReader(FileInfo[])

Instantiates a MultiFileTextReader which works on the specified set of files. The files are opened with BOM sniffing defaulting to UTF8 encoding.

Declaration

public MultiFileTextReader(params FileInfo[] files)

Parameters

Type	Name	Description
System.IO.FileInfo[]	files

MultiFileTextReader(String[])

Instantiates a MultiFileTextReader which works on the files or directories passed as the parameter. Directories are recursed into, files are opened UTF8 with BOM sniffing.

Declaration

public MultiFileTextReader(params string[] filesOrDirectories)

Parameters

Type	Name	Description
System.String[]	filesOrDirectories	The set of file names or directory names to work on

Properties

CurrentFile

Allows access to the FileInfo of the currently worked-on file. If null, EOF has been reached.

Declaration

public FileInfo CurrentFile { get; }

Property Value

Type	Description
System.IO.FileInfo

Methods

Close()

Closes the overall file set. An attempt to read more data will lead to an exception.

Declaration

public override void Close()

Overrides

System.IO.TextReader.Close()

Peek()

Not implemented.

Declaration

public override int Peek()

Returns

Type	Description
System.Int32	Always throws exception.

Overrides

System.IO.TextReader.Peek()

Read()

Reads the next character from the set of input files, advances the current file as necessary.

Declaration

public override int Read()

Returns

Type	Description
System.Int32	The next input character or -1 if EOF (of the concatenation) is reached.

Overrides

System.IO.TextReader.Read()

Read(Char[], Int32, Int32)

Reads a block of characters from the virtual concatenation of text files.

Declaration

public override int Read(char[] buffer, int index, int count)

Parameters

Type	Name	Description
System.Char[]	buffer	The buffer to store the data in (see TextReader.Read())
System.Int32	index	The index to start storing characters in the buffer.
System.Int32	count	The maximum number of characters to read

Returns

Type	Description
System.Int32	0 on EOF, or the number of characters read which may be 0 < n <= count

Overrides

System.IO.TextReader.Read(System.Char[], System.Int32, System.Int32)

ReadBlock(Char[], Int32, Int32)

Reads a block of characters from the virtual concatenation of text files.

Declaration

public override int ReadBlock(char[] buffer, int index, int count)

Parameters

Type	Name	Description
System.Char[]	buffer	The buffer to store the data in (see TextReader.Read())
System.Int32	index	The index to start storing characters in the buffer
System.Int32	count	The number of characters to read

Returns

Type	Description
System.Int32	The number of characters read. Unlike Read(buffer, index, count), this method will always attempt to read count characters and will automatically advance to the next file if the current file does not contain enough data.

Overrides

System.IO.TextReader.ReadBlock(System.Char[], System.Int32, System.Int32)

ReadLine()

Reads the next line of input from the concatenation of text files.

Declaration

public override string ReadLine()

Returns

Type	Description
System.String

Overrides

System.IO.TextReader.ReadLine()

ReadToEnd()

Not implemented.

Declaration

public override string ReadToEnd()

Returns

Type	Description
System.String	Always throws exception.

Overrides

System.IO.TextReader.ReadToEnd()
