BinaryPrimitives.TryReadInt64BigEndian(ReadOnlySpan<Byte>, Int64) 方法
定义
public:
static bool TryReadInt64BigEndian(ReadOnlySpan<System::Byte> source, [Runtime::InteropServices::Out] long % value);
public static bool TryReadInt64BigEndian (ReadOnlySpan<byte> source, out long value);
static member TryReadInt64BigEndian : ReadOnlySpan<byte> * int64 -> bool
Public Shared Function TryReadInt64BigEndian (source As ReadOnlySpan(Of Byte), ByRef value As Long) 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
- Int64
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
如果范围足够大,可以包含 Int64,则为 true;否则为 false。true if the span is large enough to contain an Int64; otherwise, false.
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.
