public bool UseOnlyOverlappedIO { get; set; }

[System.Obsolete("UseOnlyOverlappedIO has been deprecated and is not supported.")]
public bool UseOnlyOverlappedIO { get; set; }

member this.UseOnlyOverlappedIO : bool with get, set

[<System.Obsolete("UseOnlyOverlappedIO has been deprecated and is not supported.")>]
member this.UseOnlyOverlappedIO : bool with get, set

Public Property UseOnlyOverlappedIO As Boolean

Boolean

true如果 Socket 仅使用重叠 I/O，则为 .NET Framework ;否则为 false。默认为 false。

套接字已绑定到完成端口。

仅.NET Framework：对于要调用DuplicateAndClose的将Socket此属性true设置为。否则，框架可能会向套接字分配完成端口，这将禁止使用 DuplicateAndClose。

在 .NET 5+ (包括 .NET Core) 版本中，此属性的值始终 false为，并且无法更改其值。
