在变量中存储一个十六进制值（DIM XX为＆QUOT;六角＆QUOT;）在VB.NET [英] Storing a hexadecimal value in a variable (Dim xx as "Hex") in VB.NET

问题描述

如何存储在变量中的十六进制数字没有它成为一个小数点？

How can I store a hexadecimal number in a variable without it becoming a decimal?

还是我的有无将其存储为一个字符串或整数？

Or do I have to store it as either a string or integer?

推荐答案

在.NET整数不存储为小数，它们被存储为二进制文件中的补重新presentation。十进制和十六进制是reoresenting更人性化的方式的数量只是不同的方式。

Integers in .NET are not stored as decimal, they are stored as binary in two's complement representation. Both decimal and hexadecimal are just different ways of reoresenting the number in a more human-friendly way.

如果要输出一个数字为十六进制，你可以用x或X格式说明ToString方法（它的输出和较低分别为大写）以指定字符的可选固定数量的 N，其中n是字符数

If you want to output a number as hexadecimal you can use the "x" or "X" format specifier with the ToString method (which output lower- and upper-case respectively) with an optional fixed number of characters specified as "n" where n is the number of characters.

输出一个整数，为十六进制的一些例子：

Some examples of outputting an integer as hex:

Dim n as Integer = &HBEEF;
Console.WriteLine(n.ToString("x")) ' output in lower case, e.g. beef '
Console.WriteLine(n.ToString("X")) ' output in upper case, e.g. BEEF '
Console.WriteLine(n.ToString("X8")) ' upper case & 8 chars, e.g. 0000BEEF '
