段落的正则表达式 [英] regular expression for paragraph

问题描述

我想在一个不包含数据的文本框上设置validatior，而不是包含空白的140个letor

I want to set validatior on a text box which not contain data more then 140 letors with white space

推荐答案

TextBox具有一个名为MaxLength的属性.
将该属性的值设置为140，就可以完成.

TextBox has a property called MaxLength.
Set the value of this property to 140 and you are done.

此正则表达式将执行...
[s \ S] {0,140}

This regular expression will do...
[s\S]{0,140}
