FileStream Constructor (IntPtr, FileAccess, Boolean)
Initializes a new instance of the FileStream class for the specified file handle, with the specified read/write permission and FileStream instance ownership.
Assembly: mscorlib (in mscorlib.dll)
[ObsoleteAttribute("This constructor has been deprecated. Please use new FileStream(SafeFileHandle handle, FileAccess access) instead, and optionally make a new SafeFileHandle with ownsHandle=false if needed. http://go.microsoft.com/fwlink/?linkid=14202")] public FileStream( IntPtr handle, FileAccess access, bool ownsHandle )
A file handle for the file that the current FileStream object will encapsulate.
- Type: System.IO.FileAccess
true if the file handle will be owned by this FileStream instance; otherwise, false.
access is not a field of FileAccess.
The caller does not have the required permission.
An I/O error, such as a disk error, occurred.
The stream has been closed.
The access requested is not permitted by the operating system for the specified file handle, such as when access is Write or ReadWrite and the file handle is set for read-only access.
The FileStream object is given the specified access to the file. The ownership of the handle will be as specified. If this process owns the handle, a call to the Close method will also close the handle and the file's handle count is decremented. The FileStream object is given the default buffer size of 4096 bytes.
FileStream assumes that it has exclusive control over the handle. Reading, writing, or seeking while a FileStream is also holding a handle could result in data corruption. For data safety, call Flush before using the handle, and avoid calling methods other than Close after you are done using the handle.
FileShare.Read is the default for those FileStream constructors without a FileShare parameter.
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.
