我如何用逗号分隔整数（1234,212,123） [英] How I Have To Separate Integer With Commas Like (1234,212,123)

问题描述

在jsp页面中，（在struds框架中）我定义了一个html：text字段，field属性是String类型（在bean中定义）。现在，如果我在文本字段中输入整数值，我怎么用逗号分隔这些整数，如（1234,212,123）

解决方案

你需要告诉 ToString 两件事：1）应该使用什么文化来生产某种类型的分隔符，2）指出用于分隔符的内容;它可能是特定文化的默认值。

您还可以定义要使用的文化当前主题：

In a jsp page,(in struds framework) I have defined a html:text field and the field property is String type(defined in bean). Now if I enter the integer value in text field how i have to separate these integer with commas like (1234,212,123)

解决方案

You need to tell ToString two things: 1) what culture should be used to produce certain type of separator, 2) indicate what to use for the separator; it could be the default for the specific culture.

Please see:

You can also define the culture to use for the current thread:

The most customized way of having any separators with any number of digits is shown in this article: http://social.msdn.microsoft.com/Forums/vstudio/en-US/8e1b235f-c10e-49f9-8c4f-13af717944fe/number-format-string-thousands-separator-with-any-number-of-decimal-places?forum=csharpgeneral[^].
