c# sizeof decimal?
提问by P a u l
Unclear on the sizeof for decimal types. Does the size in bytes vary by precision as in sql server? Is the precision variable for the c# type 'decimal'?
十进制类型的 sizeof 不清楚。以字节为单位的大小是否与 sql server 中的精度不同?c# 类型的精度变量是“十进制”吗?
I don't want to turn on unsafe code to just call sizeof on a decimal type. How would you approach this?
我不想打开不安全的代码来只在十进制类型上调用 sizeof 。你会如何处理这个问题?

As others have said, decimal
is always 16 bytes (128 bits). The precision of decimal
is always 28/29 digits. It's a floating point type, unlike SQL's DECIMAL
type. See my article on itfor more details.
正如其他人所说,decimal
总是 16 字节(128 位)。的精度decimal
始终为 28/29 位。它是一种浮点类型,与 SQL 的DECIMAL
类型不同。有关更多详细信息,请参阅我的文章。

The size of a System.Decimal in the .NET Framework is fixed at 16 Bytes.
.NET Framework 中 System.Decimal 的大小固定为 16 字节。

128-bit precise decimal values with 28-29 significant digits, 128 bit = 16 byte
具有 28-29 位有效数字的 128 位精确十进制值,128 位 = 16 字节
