BinaryPrimitives.TryReadUInt64BigEndian(ReadOnlySpan<Byte>, UInt64) 方法

定义

重要

此 API 不符合 CLS。

从字节只读范围的开头,将 UInt64 读取为大字节序。Reads a UInt64 from the beginning of a read-only span of bytes, as big endian.

public:
 static bool TryReadUInt64BigEndian(ReadOnlySpan<System::Byte> source, [Runtime::InteropServices::Out] System::UInt64 % value);
[System.CLSCompliant(false)]
public static bool TryReadUInt64BigEndian (ReadOnlySpan<byte> source, out ulong value);
[<System.CLSCompliant(false)>]
static member TryReadUInt64BigEndian : ReadOnlySpan<byte> * uint64 -> bool
Public Shared Function TryReadUInt64BigEndian (source As ReadOnlySpan(Of Byte), ByRef value As ULong) As Boolean

参数

source
ReadOnlySpan<Byte>

要读取的字节只读范围。The read-only span of bytes to read.

value
UInt64

此方法返回时,值作为大字节序从字节只读范围中读取。When this method returns, the value read out of the read-only span of bytes, as big endian.

返回

Boolean

如果范围足够大,可以包含 UInt64,则为 true;否则为 falsetrue if the span is large enough to contain a UInt64; otherwise, false.

属性

注解

从跨度的开头精确读取8个字节。Reads exactly 8 bytes from the beginning of the span.
