我使用下面的语句在我的代码
I am generating a GUID using the following statement in my code
byte[ ] keyBytes = Encoding.UTF8.GetBytes( Guid.NewGuid( ).ToString( ).Substring( 0, 12 ) );
不过,会生成一个GUID的时候,我发现它包含了连字符了。我怎么去生成只包含字母(大写和小写)和数字的GUID?我不想连字符。有人可以给我这样的想法?
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?
推荐答案请注意,你是在谈论一个GUID的(规范)的字符串表示。该GUID本身实际上是一个128位的整数值。
Note that you are talking about the (canonical) string representation of a Guid. The Guid itself is actually a 128-bit integer value.
您可以使用带有的 Guid.ToString(字符串) 超载。
You can use the "N" specifier with the Guid.ToString(String) overload.
Guid.NewGuid().ToString("N");默认情况下字母都是小写。
By default letters are lowercase. A Guid with only uppercase letters can only be achieved by manually converting them all to uppercase, example:
Guid.NewGuid().ToString("N").ToUpper();一个没有意义的。一个GUID字符串表示是十六进制的,因此总会(以及最有可能的),同时包含。
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.
