FileStream Constructor (String, FileMode, FileAccess, FileShare, Int32)

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Initializes a new instance of the FileStream class with the specified path, creation mode, read/write and sharing permission, and buffer size.

Namespace:  System.IO
Assembly:  System.IO (in System.IO.dll)

public FileStream(
	string path,
	FileMode mode,
	FileAccess access,
	FileShare share,
	int bufferSize
)

Parameters

path
Type: System..::..String
A relative or absolute path for the file that the current FileStream object will encapsulate.
mode
Type: System.IO..::..FileMode
A constant that determines how to open or create the file.
access
Type: System.IO..::..FileAccess
A constant that determines how the file can be accessed by the FileStream object. This gets the CanRead and CanWrite properties of the FileStream object. CanSeek is true if path specifies a disk file.
share
Type: System.IO..::..FileShare
A constant that determines how the file will be shared by processes.
bufferSize
Type: System..::..Int32
A positive Int32 value greater than 0 indicating the buffer size. For bufferSize values between one and eight, the actual buffer size is set to eight bytes.

CanSeek is true for all FileStream objects that encapsulate files. If path indicates a device that does not support seeking, the CanSeek property on the resulting FileStream is false. For additional information, see CanSeek.

Caution noteCaution

When you compile a set of characters with a particular cultural setting and retrieve those same characters with a different cultural setting, the characters might not be interpretable, and could cause an exception to be thrown.
