区域与语言CultureInfo

CultureInfo 类

命名空间:

System.Globalization

程序集:

System.Globalization.dll

提供有关特定区域性（对于非托管代码开发，则称为“区域设置”）的信息。这些信息包括区域性的名称、书写系统、使用的日历、字符串的排序顺序以及对日期和数字的格式化设置。

LCID

LCID,全称 Locale Identifier,区域设置标识符,用于确定特定地区和语言的区域设置
使用LCID是为了标识不同地区和语言的代码。它是Locale Identifier（区域设置标识符）的缩写，用于表示不同地区和语言的组合。
每个LCID都是一个32位的无符号整数，由语言ID和子语言ID组成。语言ID是指一种语言，而子语言ID指的是地区或区域设置。
在Windows操作系统中，LCID被广泛用于识别和设置地区设置，如日期和时间格式、货币单位、数字格式、键盘布局等。

本文演示打印显示所有区域信息到表格中.

新建Windows应用程序CultureDemo

FormCulture窗体设计如图：

窗体设计器代码如下：

FormCulture.Designer.cs文件


namespace CultureDemo
{
    partial class FormCulture
    {
        /// <summary>
        /// 必需的设计器变量。
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        /// 清理所有正在使用的资源。
        /// </summary>
        /// <param name="disposing">如果应释放托管资源，为 true；否则为 false。</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }
