generating GUID without hyphen
提问by Harish Kumar
I am generating a GUID using the following statement in my code
我在代码中使用以下语句生成 GUID
byte[ ] keyBytes = Encoding.UTF8.GetBytes( Guid.NewGuid( ).ToString( ).Substring( 0, 12 ) );
But, when a GUID is generated, I find that it contains the hyphen character too. How do I go about in generating a GUID with only letters (upper case and lower case) and numbers? I do not want the hyphen. Can someone give me so idea?
但是，当生成 GUID 时，我发现它也包含连字符。如何生成仅包含字母（大写和小写）和数字的 GUID？我不想要连字符。有人可以给我这样的想法吗？

Note that you are talking about the (canonical) string representation of a Guid. The Guid itself is actually a 128-bit integer value.
请注意，您正在谈论 Guid 的（规范）字符串表示形式。Guid 本身实际上是一个 128 位整数值。
You can use the "N" specifier with the Guid.ToString(String)overload.
您可以在Guid.ToString(String)重载中使用“N”说明符。
Guid.NewGuid().ToString("N");
By default letters are lowercase. A Guid with only uppercase letters can only be achieved by manually converting them all to uppercase, example:
默认情况下字母是小写的。只有大写字母的 Guid 只能通过手动将它们全部转换为大写来实现，例如：
Guid.NewGuid().ToString("N").ToUpper();
A guid with only either letter or digits makes no sense. A guid string representation is hexadecimal, and thus will always (well most likely) contain both.
只有字母或数字的 guid 没有任何意义。guid 字符串表示是十六进制的，因此将始终（很可能）包含两者。

Guid.NewGuid().ToString().Replace("-", string.Empty)
