“字节”的后缀是什么(类型字符)? VB.NET中的数字常量? [英] What's the suffix (type character) for "Byte" numeric constants in VB.NET?
问题描述
只是出于好奇:
我知道我可以告诉编译器是否希望将值解释为某些数字类型,例如作为整数(32位带符号),通过这种方式在常量值后面附加一个 I(类型字符):
I know I can tell the compiler if I want a value to be interpreted as a certain numeric type, e.g. as Integer (32 bit signed), this way appending an "I" (type character) to the constant value:
Private Function GetTheAnswerAsInteger() As Integer
Return 42I
End Function
还有 S(缩写), D(十进制)等。
There's also "S" for Short, "D" for Decimal, etc.
但是后缀为Byte 是什么?提示:它不是显而易见的一个 B ...
But what is the suffix for Byte? Hint: it's not the obvious one "B"...
推荐答案
没有一个。如果需要区分常量的整数和字节(例如,调用适当的重载),则需要进行强制转换。
There isn't one. If you need to distinguish between an integer and a byte (e.g. to call an appropriate overload) for a constant, you need to cast.
(C#中也是如此,顺便说一句。)
(The same is true in C#, by the way.)
字节没有文字类型字符或
标识符类型字符。
Byte has no literal type character or identifier type character.
还有一个类型字符和文字后缀的列表。
