asp.net mvc - DataAnnotations StringLength Attribute MVC - without max value -

asp.net mvc - DataAnnotations StringLength Attribute MVC - without max value -

I am using data annotation for model recognition in MVC4 and currently using StringLengthAttribute, but I I do not want to specify the maximum value (currently set to 50) but want to specify a minimum string length value.

Is there any way to specify only a minimum length? Maybe I can use another feature?

My current code is:

  [required] [datatype (datatype password)] [display (name = "confirm new password"]] [string lang (50, minimum length = 7)] (compare ("newpassword", error message = "new password and confirm that no new password has been matched.")] Public String Confirm Newpassword {get; set;} < / Code>   Any help is greatly appreciated.   
 
   Only Is there a way to specify a minimum length? Maybe I can use another feature?   
  Using standard data annotations, No. You must specify maximum length Only other parameters are optional.   
 In this situation, I give some suggestions like this:  
  [string lang (int.MaxValue, MinimalLength = 7)]    You can also use a Regex (regular expression) feature as (Regular expression: ("? ^ (?:. * [Az]) {7,} $", error message = "the length of the string should be greater than or equal to 7 characters . ")]

apache - How to do an URL rewrite that works with a
pre-existing .htaccess file? -



    I have a platform that is currently available through the URL:    Www.websitecom / index.php? App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.    RewriteRule ^ forum $ /index.php?app=forums    Alternatively, you redirect from a 301 / forum to index.php URL .   By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,     






c# - EventSource's response has a MIME type ("text/html") that is
not "text/event-stream" -



    When I try to hook my controller to EventSource, it keeps saying:    EventSource Response contains a MIME type ("text / html") that is not "text / event-stream" canceling connection.
