Constructors

MultiFileTextReader(DirectoryInfo, string, bool)

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
DirectoryInfo rootDirectory

The directory in which to search for applicable files.
string fileFilter

If non-null, only files which match the filter are added to the file set (see System.IO.DirectoryInfo.GetFiles()).
bool recurse

If true, subdirectories are scanned for matching false. Otherwise, only files in the specified root directory are considered.

MultiFileTextReader(params 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
FileInfo[] files

MultiFileTextReader(params 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
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
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

Peek()

Not implemented.

Declaration
public override int Peek()
Returns
Type Description
int

Always throws exception.
Overrides

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
int

The next input character or -1 if EOF (of the concatenation) is reached.
Overrides

Read(char[], int, int)

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
char[] buffer

The buffer to store the data in (see TextReader.Read())
int index

The index to start storing characters in the buffer.
int count

The maximum number of characters to read
Returns
Type Description
int

0 on EOF, or the number of characters read which may be 0 < n <= count
Overrides

ReadBlock(char[], int, int)

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
char[] buffer

The buffer to store the data in (see TextReader.Read())
int index

The index to start storing characters in the buffer
int count

The number of characters to read
Returns
Type Description
int

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

ReadLine()

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

Declaration
public override string ReadLine()
Returns
Type Description
string
Overrides

ReadToEnd()

Not implemented.

Declaration
public override string ReadToEnd()
Returns
Type Description
string

Always throws exception.
