正则表达式至少10个字符

I need a regular expression which checks that a string is at least 10 characters long. It does not matter what those character are.

我需要一个正则表达式来检查一个字符串是否至少10个字符长。这些角色是什么并不重要。

You can use:

您可以使用：

.{10,}

Since . does not match a newline by default you'll have to use a suitable modifier( if supported by your regex engine) to make . match even the newline. Example in Perl you can use the s modifier.

自从。默认情况下，与换行符不匹配，您必须使用合适的修饰符（如果您的正则表达式引擎支持）。甚至匹配换行符。在Perl中的示例，您可以使用s修饰符。

Alternatively you can use [\s\S] or [\d\D] or [\w\W] in place of .

或者，您可以使用[\ s \ S]或[\ d \ D]或[\ w \ W]代替。

This will match a string of any 10 characters, including newlines:

这将匹配任意10个字符的字符串，包括换行符：

[\s\S]{10,}

(In general, . does not match newlines.)

（通常，。与新行不匹配。）

Does the language you're using not have a string length function (or a library with such a function)? Is it very difficult to implement your own? This seems overkill for regex, but you could just use something like .{10,} if you really wanted to. In langauges that have length functions, it might look something like if (str.length()>10) lenGeq10=true or if (length(str) > 10) lenGeq10=true, etc... and if whitespace is a concernt, many libraries also have triming functions to strip whitespace, example: if (length(trim(str)) > 10) lenGeq10=true...

您使用的语言是否没有字符串长度函数（或具有此类函数的库）？实施自己的很难吗？对于正则表达式来说这似乎有些过分，但如果你真的想要，你可以使用类似。{10，}的东西。在具有长度函数的语言中，它可能看起来像if（str.length（）> 10）lenGeq10 = true或if（length（str）> 10）lenGeq10 = true等等......如果空白是一个有意义的话，许多库也有剥离空格的转移函数，例如：if（length（trim（str））> 10）lenGeq10 = true ...

A C# solution to see if the string matters as defined by your parameters..

一个C＃解决方案，用于查看字符串是否与您的参数所定义的一样重要。

string myString = "Hey it's my string!";
bool ItMatters;

ItMatters = myString.Length >= 10;

\S{10,}

\ S {10，}
