Namespace:

System.IO

Assembly:

System.Runtime.dll

Overloads

Write(SafeFileHandle, IReadOnlyList<ReadOnlyMemory<Byte>>, Int64)	Writes a sequence of bytes from given buffers to given file at given offset.
Write(SafeFileHandle, ReadOnlySpan<Byte>, Int64)	Writes a sequence of bytes from given buffer to given file at given offset.

Write(SafeFileHandle, IReadOnlyList<ReadOnlyMemory<Byte>>, Int64)

Source:

RandomAccess.cs

Writes a sequence of bytes from given buffers to given file at given offset.

public:
 static void Write(Microsoft::Win32::SafeHandles::SafeFileHandle ^ handle, System::Collections::Generic::IReadOnlyList<ReadOnlyMemory<System::Byte>> ^ buffers, long fileOffset);

public static void Write (Microsoft.Win32.SafeHandles.SafeFileHandle handle, System.Collections.Generic.IReadOnlyList<ReadOnlyMemory<byte>> buffers, long fileOffset);

static member Write : Microsoft.Win32.SafeHandles.SafeFileHandle * System.Collections.Generic.IReadOnlyList<ReadOnlyMemory<byte>> * int64 -> unit

Public Shared Sub Write (handle As SafeFileHandle, buffers As IReadOnlyList(Of ReadOnlyMemory(Of Byte)), fileOffset As Long)

Parameters

handle

SafeFileHandle

The file handle.

buffers

IReadOnlyList<ReadOnlyMemory<Byte>>

A list of memory buffers. This method copies the contents of these buffers to the file.

fileOffset

Int64

The file position to write to.

Exceptions

ArgumentNullException

handle or buffers is null.

ArgumentException

handle is invalid.

ObjectDisposedException

The file is closed.

NotSupportedException

The file does not support seeking (pipe or socket).

ArgumentOutOfRangeException

fileOffset is negative.

UnauthorizedAccessException

handle was not opened for writing.

IOException

An I/O error occurred.

Remarks

Position of the file is not advanced.

Write(SafeFileHandle, ReadOnlySpan<Byte>, Int64)

Source:

RandomAccess.cs

Writes a sequence of bytes from given buffer to given file at given offset.

public:
 static void Write(Microsoft::Win32::SafeHandles::SafeFileHandle ^ handle, ReadOnlySpan<System::Byte> buffer, long fileOffset);

public static void Write (Microsoft.Win32.SafeHandles.SafeFileHandle handle, ReadOnlySpan<byte> buffer, long fileOffset);

static member Write : Microsoft.Win32.SafeHandles.SafeFileHandle * ReadOnlySpan<byte> * int64 -> unit

Public Shared Sub Write (handle As SafeFileHandle, buffer As ReadOnlySpan(Of Byte), fileOffset As Long)

Parameters

handle

SafeFileHandle

The file handle.

buffer

ReadOnlySpan<Byte>

A region of memory. This method copies the contents of this region to the file.

fileOffset

Int64

The file position to write to.

Exceptions

ArgumentNullException

handle is null.

ArgumentException

handle is invalid.

ObjectDisposedException

The file is closed.

NotSupportedException

The file does not support seeking (pipe or socket).

ArgumentOutOfRangeException

fileOffset is negative.

UnauthorizedAccessException

handle was not opened for writing.

IOException

An I/O error occurred.

Remarks
