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

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 -> unitPublic 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. In .NET 11 and later versions, this parameter is ignored for files that don't support seeking, such as pipes, sockets, and character devices. The value must be non-negative even when it's ignored.
Exceptions
handle or buffers is null.
handle is invalid.
The file is closed.
In .NET 10 and earlier versions, the file doesn't support seeking (for example, a pipe or socket).
fileOffset is negative.
handle was not opened for writing.
An I/O error occurred.
Remarks
For files that support seeking, the file position is not advanced.
