BigInteger.TryWriteBytes(Span<Byte>, Int32, Boolean, Boolean) 方法

定义

命名空间:
System.Numerics
程序集:
System.Runtime.Numerics.dll
程序集:
netstandard.dll

使用尽可能少的字节数将此 BigInteger 的值复制为小端二进制补码字节。Copies the value of this BigInteger as little-endian twos-complement bytes, using the fewest number of bytes possible. 如果值为零，则输入其元素为 0x00 的字节。If the value is zero, outputs one byte whose element is 0x00.

public bool TryWriteBytes (Span<byte> destination, out int bytesWritten, bool isUnsigned = false, bool isBigEndian = false);
member this.TryWriteBytes : Span<byte> * int * bool * bool -> bool
Public Function TryWriteBytes (destination As Span(Of Byte), ByRef bytesWritten As Integer, Optional isUnsigned As Boolean = false, Optional isBigEndian As Boolean = false) As Boolean

参数

destination
Span<Byte>

应写入生成字节的目标跨度。The destination span to which the resulting bytes should be written.

bytesWritten
Int32

写入到 destination 的字节数。The number of bytes written to destination.

isUnsigned
Boolean

如果使用无符号编码，则为 true；否则为 false。true to use unsigned encoding; otherwise, false.

isBigEndian
Boolean

如果以大端字节顺序写入字节，则为 true；否则为 false。true to write the bytes in a big-endian byte order; otherwise, false.

返回

Boolean

如果字节满足 destination，则为 true；如果由于空间不足而无法写入所有字节，则为 false。true if the bytes fit in destination; false if not all bytes could be written due to lack of space.

例外

OverflowException

isUnsigned 为 true 且 Sign 为负。isUnsigned is true and Sign is negative.
