File

File class

Provides methods for manipulating files. This is a static type with no instance services. You should never create instances of it by any means.

Methods

Method	Description
static void AppendAllLines(const String&, const SharedPtr<Collections::Generic::IEnumerable<String>>&, const EncodingPtr&)	Appends strings from the specified collection of strings to the specified file using the specified encoding by writing each string in a new line. If the specified file does not exist, it is created. The file is closed after writing all strings.
static void AppendAllText(const String&, const String&, const EncodingPtr&)	Appends the specified string to the specified file using the specified encoding.
static StreamWriterPtr AppendText(const String&)	Creates a StreamWriter object that appends text to the specified file using UTF-8 encoding. If the specified file does not exist, it is created.
static void Copy(const String&, const String&, bool)	Copies the specified file to the specified location. If the destination file already exists, a parameter specifies if it should be overwritten.
static FileStreamPtr Create(const String&, int32_t, FileOptions)	Creates a new file (or overwrites existing) and opens it for reading and writing access using the specified buffer size and options.
static StreamWriterPtr CreateText(const String&)	Creates a new or opens existing file for writing UTF-8 encoded text.
static void Decrypt(const String&)	NOT IMPLEMENTED.
static void Delete(const String&)	Deletes the specified file or directory.
static void Encrypt(const String&)	NOT IMPLEMENTED.
static bool Exists(const String&)	Determines if the specified path references an existing file.
static FileAttributes GetAttributes(const String&)	Returns the attributes of the specified entity.
static DateTime GetCreationTime(const String&)	Returns the creation time of the specified entity as local time.
static DateTime GetCreationTimeUtc(const String&)	Returns the creation time of the specified entity as UTC time.
static DateTime GetLastAccessTime(const String&)	Returns the last access time of the specified entity as local time.
static DateTime GetLastAccessTimeUtc(const String&)	Returns the last access time of the specified entity as UTC time.
static DateTime GetLastWriteTime(const String&)	Returns the last write time of the specified entity as local time.
static DateTime GetLastWriteTimeUtc(const String&)	Returns the last write time of the specified entity as UTC time.
static void Move(const String&, const String&)	Moves the specified file to the new location.
static FileStreamPtr Open(const String&, FileMode)	Opens the specified file in the specified mode for reading and writing and with no sharing.
static FileStreamPtr Open(const String&, FileMode, FileAccess, FileShare)	Opens the specified file in the specified mode, with the specified access type and sharing option.
static FileStreamPtr OpenRead(const String&)	Opens the specified file for reading only, in ‘Open’ mode with shared access for reading.
static StreamReaderPtr OpenText(const String&, const EncodingPtr&)	Opens the specified existing file for reading text using UTF-8 encoding with no sharing.
static FileStreamPtr OpenWrite(const String&)	Opens the specified file for writing only, in ‘OpenOrCreate’ mode with no sharing.
static ArrayPtr<uint8_t> ReadAllBytes(const String&)	Reads the content of the specified binary file to a byte array.
static ArrayPtr<String> ReadAllLines(const String&, const EncodingPtr&)	Reads the content of the specified text file line by line to an array of strings using the specified character encoding.
static String ReadAllText(const String&, const EncodingPtr&)	Reads the content of the specified text file to a single String object using the specified character encoding.
static SharedPtr<Collections::Generic::IEnumerable<String>> ReadLines(const String&, const EncodingPtr&)	Reads the content of the specified text file line by line using the specified character encoding and returns enumerable collection of strings each of which represents a single line of the file’s content.
static void Replace(const String&, const String&, const String&, bool)	Replaces the contents of a one file with another and creates a backup of the replaced file.
static void SetAttributes(const String&, FileAttributes)	Sets the specified attributes on the specified file.
static void SetCreationTime(const String&, DateTime)	NOT IMPLEMENTED.
static void SetCreationTimeUtc(const String&, DateTime)	NOT IMPLEMENTED.
static void SetLastAccessTime(const String&, DateTime)	NOT IMPLEMENTED.
static void SetLastAccessTimeUtc(const String&, DateTime)	NOT IMPLEMENTED.
static void SetLastWriteTime(const String&, DateTime)	Sets the last write time of the specified entity as local time.
static void SetLastWriteTimeUtc(const String&, DateTime)	Sets the last write time of the specified entity as UTC time.
static void WriteAllBytes(const String&, const ArrayPtr<uint8_t>&)	Overwrites the specified binary file and writes the specified bytes to it.
static void WriteAllLines(const String&, const SharedPtr<Collections::Generic::IEnumerable<String>>&, const EncodingPtr&)	Creates a new text file or overwrites the existing one and writes all strings from the specified enumerable collection of strings to it, each string on a new line, using the specified encoding.
static void WriteAllLines(const String&, const ArrayPtr<String>&, const EncodingPtr&)	Creates a new text file or overwrites the existing one and writes all strings from the specified array of strings to it, each string on a new line, using the specified encoding.
static void WriteAllText(const String&, const String&, const EncodingPtr&)	Creates a new text file or overwrites the existing one and writes the content of the specified string to it using the specified encoding.
