C# -WinForm 中英文实现, 国际化实现的简单方法
來源:http://www.jb51.net/article/45675.htm,今天看到了借鑒過了,保存一下,下次開發直接用嘻嘻
軟件行業發展到今天,國際化問題一直都占據非常重要的位置,而且應該越來越被重視。對于開發人員而言,在編寫程序之前,國際化問題是首先要考慮的一個問題,也許有時候這個問題已經在設計者的考慮范圍之內,但終歸要開發人員去做實現的。因此,如何實現國際化,是開發人員必須掌握的一項基本技能。
今天,這里要講的就是,在利用C#進行WinForm開發時,國際化是怎么實現的。鑒于時間及篇幅關系,這里僅僅介紹一種簡單的國際化實現方法,可能這里提到的方法已經有非常多人提到過,但筆者還是不厭其煩地介紹一下。
要在C#中實現國際化,需要相關資源文件,比如要在一個軟件中支持英文、中文兩種語言,那么就必須有這兩種語言的資源文件,這在C#中可以采用資源文件(后綴名為.resx)來實現,我們不妨定義英文資源文件名稱為Resource.en-US,中文資源文件名稱為Resource.zh-CN,兩種資源文件所涉及的ID都應該是一樣的(這對于其他更多的資源文件均是一樣的),只不過是展示的名稱不同罷了。
有了這兩種資源文件,接下來就要考慮如何做的問題了。為了適應多處使用的情形,這里筆者單獨編寫了一個類ResourceCulture,該類包含了一些靜態方法,主要作用是用來設置當前語言及返回當前的語言的相關字符串。該類代碼如下:
using System.Reflection;
using System.Resources;
using System.Threading;
using System.Globalization;
namespace GlobalizationTest
{
??? class ResourceCulture
??? {
??????? /// <summary>
??????? /// Set current culture by name
??????? /// </summary>
??????? /// <param name="name">name</param>
??????? public static void SetCurrentCulture(string name)
??????? {
??????????? if (string.IsNullOrEmpty(name))
??????????? {
??????????????? name = "en-US";
??????????? }
??????????? Thread.CurrentThread.CurrentCulture = new CultureInfo(name);
??????? }
??????? /// <summary>
??????? /// Get string by id
??????? /// </summary>
??????? /// <param name="id">id</param>
??????? /// <returns>current language string</returns>
??????? public static string GetString(string id)
??????? {
??????????? string strCurLanguage = "";
??????????? try
??????????? {
??????????????? ResourceManager rm = new ResourceManager("GlobalizationTest.Resource", Assembly.GetExecutingAssembly());
??????????????? CultureInfo ci = Thread.CurrentThread.CurrentCulture;
??????????????? strCurLanguage = rm.GetString(id, ci);
??????????? }
??????????? catch
??????????? {
??????????????? strCurLanguage = "No id:" + id + ", please add.";
??????????? }
??????????? return strCurLanguage;
??????? }
??? }
}
在Form1中的代碼如下:
/**
?* This project is just a example to show how to do the globalization in C# winform.
?* You and rebuild and/or modify it by yourself if you want.
?* Specially, this project was created in Visual Studio 2010.
?*
?* Project Name : GlobalizationTest
?* Create Date? : April 29th, 2010
?* */
using System;
using System.Windows.Forms;
namespace GlobalizationTest
{
??? public partial class Form1 : Form
??? {
??????? public Form1()
??????? {
??????????? InitializeComponent();
??????? }
??????? /// <summary>
??????? /// Set the resource culture
??????? /// </summary>
??????? private void SetResourceCulture()
??????? {
??????????? // Set the form title text
??????????? this.Text = ResourceCulture.GetString("Form1_frmText");
??????????? // Set the groupbox text
??????????? this.gbLanguageView.Text = ResourceCulture.GetString("Form1_gbLanguageViewText");
??????????? this.gbLanguageSelection.Text = ResourceCulture.GetString("Form1_gbLanguageSelectionText");
??????????? // Set the label text
??????????? this.lblCurLanguageText.Text = ResourceCulture.GetString("Form1_lblCurLanguageText");
??????????? this.lblNameText.Text = ResourceCulture.GetString("Form1_lblNameText");
??????????? this.lblPhoneText.Text = ResourceCulture.GetString("Form1_lblPhoneText");???
??????????? // Set the button text
??????????? this.btnMsgShow.Text = ResourceCulture.GetString("Form1_btnMsgShowText");
??????????? // Set radiobutton text
??????????? this.rbEnglish.Text = ResourceCulture.GetString("Language_EnglishText");
??????????? this.rbChinese.Text = ResourceCulture.GetString("Language_ChineseText");
??????????? // Set the current language text
??????????? if (rbEnglish.Checked)
??????????? {
??????????????? this.lblCurLanguage.Text = ResourceCulture.GetString("Language_EnglishText");
??????????? }
??????????? else if (rbChinese.Checked)
??????????? {
??????????????? this.lblCurLanguage.Text = ResourceCulture.GetString("Language_ChineseText");
??????????? }
??????? }
??????? private void Form1_Load(object sender, EventArgs e)
??????? {
??????????? // Set the default language
??????????? ResourceCulture.SetCurrentCulture("en-US");
??????????? this.SetResourceCulture();
??????? }
??????? private void btnMsgShow_Click(object sender, EventArgs e)
??????? {
??????????? if(string.IsNullOrEmpty(txtName.Text))
??????????? {
??????????????? MessageBox.Show(ResourceCulture.GetString("Form1_msgbox_nameText"), ResourceCulture.GetString("Form1_msgbox_TitleText"),
??????????????????? MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
??????????????? return;
??????????? }
??????????? if (string.IsNullOrEmpty(txtPhone.Text))
??????????? {
??????????????? MessageBox.Show(ResourceCulture.GetString("Form1_msgbox_phoneText"), ResourceCulture.GetString("Form1_msgbox_TitleText"),
??????????????????? MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
??????????????? return;
??????????? }
??????????? MessageBox.Show(ResourceCulture.GetString("Form1_msgbox_InfoText") + txtName.Text + ", " + txtPhone.Text,
??????????????? ResourceCulture.GetString("Form1_msgbox_TitleText"), MessageBoxButtons.OK, MessageBoxIcon.Information);
??????? }
??????? private void rbEnglish_CheckedChanged(object sender, EventArgs e)
??????? {
??????????? ResourceCulture.SetCurrentCulture("en-US");
??????????? this.SetResourceCulture();
??????? }
??????? private void rbChinese_CheckedChanged(object sender, EventArgs e)
??????? {
??????????? ResourceCulture.SetCurrentCulture("zh-CN");
??????????? this.SetResourceCulture();
??????? }
??? }
}
最終的效果如下圖1和圖2所示:

歸結起來,要在C#的WinForm中實現國際化,至少需要做好以下幾點:
(1)準備所需資源文件(如本文中提到的英文和中文資源文件);
(2)引入命名空間(包括:System.Reflection、System.Resources、System.Threading和System.Globalization);
(3)實例化資源管理器(即ResourceManager);
(4)設置當前進程的語言區域;
(5)通過資源管理器從指定的資源文件中獲取所需值。
通過上述的方法即可簡單實現國際化。
