从 Reader 至少可用的指定字节数读取。

protected System.Threading.Tasks.ValueTask<System.IO.Pipelines.ReadResult> ReadAtLeastAsync (int requiredBytes, bool allowEmpty, System.Threading.CancellationToken cancellationToken);

member this.ReadAtLeastAsync : int * bool * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<System.IO.Pipelines.ReadResult>

Protected Function ReadAtLeastAsync (requiredBytes As Integer, allowEmpty As Boolean, cancellationToken As CancellationToken) As ValueTask(Of ReadResult)

参数

requiredBytes: Int32

必须可用的字节数。

allowEmpty: Boolean

true 如果读取任何字节之前遇到流末尾，则允许返回 0 字节。

cancellationToken: CancellationToken

取消标记。

返回

ValueTask<ReadResult>

ReadResult包含至少requiredBytes字节数。

例外

OperationCanceledException

Thrown if IsCanceled.

EndOfStreamException

如果在 IsCompleted 有 requiredBytes 字节之前引发。如果读取了 0 个字节且 allowEmpty 为 true，则不引发。
