国际化是桌面端的程序的必不可少的一个功能，基本上每个程序都会需要这样功能，但是多资源的文件来源可以多种多样，包含xml文件、resource资源文件等等，现先介绍这两种多语言文件的实现国际化的方法。
一、resource资源文件
无论是WPF还是WinForm都对这种资源文件提供支持，切换语言时，只需要设置Thread.CurrentThread.CurrentUICulture就可进行语言的切换。UI使用多语言的方法如下:
1 //定义资源的一个变量 2 private ResourceManager _resouceManager = null; 3 4 public ApplyResourceFile() 5 { 6 InitializeComponent(); 7 8 LoadResource(); 9 } 10 11 private void LoadResource() 12 { 13 _resouceManager = new ResourceManager("LocalizeWinForm.LanguageResources.Language", typeof(ApplyResourceFile).Assembly); 14 } 15 16 /// <summary> 17 /// 通过Key得到相应的语言资源文件中定义的文本 18 /// </summary> 19 /// <param name="str"></param> 20 /// <returns></returns> 21 public string GetMsg(string str) 22 { 23 return _resouceManager.GetString(str); 24 } 25 26 private void rb_English_CheckedChanged(object sender, EventArgs e) 27 { 28 CultureInfo cultureInfo = null; 29 if (rb_English.Checked) 30 { 31 Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("en-GB"); 32 } 33 else 34 { 35 Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("zh-Hans"); 36 } 37 }
二、XML资源
1.语言文件定义Language.en-GB.xml
1 <?xml version="1.0" encoding="utf-8" ?> 2 <!--本文档集成所有窗体的控件配置--> 3 <language id="en-GB" name="english"> 4 <btn_Close>Close</btn_Close> 5 <btn_Ok>Ok</btn_Ok> 6 <cb_basketball>basketball</cb_basketball> 7 <cb_football>football</cb_football> 8 <cb_tennis>tennis</cb_tennis> 9 <groupBox_FavoriteSport>What is you favorite sport?</groupBox_FavoriteSport> 10 <groupBox_Gender>Gender</groupBox_Gender> 11 <lbl_Age>Age</lbl_Age> 12 <lbl_Name>Name</lbl_Name> 13 <rb_Female>Female</rb_Female> 14 <rb_Male>Male</rb_Male> 15 </language>
2.简单定义一个XMLHelper类，来处理XML中的数据
1 internal class XMLHealper 2 { 3 #region 字段 4 5 private XmlDocument _xmlDoc = new XmlDocument(); 6 7 #endregion 8 9 #region 构造函数 10 11 public XMLHealper() 12 { 13 14 } 15 16 public XMLHealper(string path) 17 { 18 OpenXML(path); 19 } 20 21 #endregion 22 23 #region 加载XML文件，创建操作对象 24 25 /// <summary> 26 /// 加载XML文件，创建操作对象 27 /// </summary> 28 public void OpenXML(string filePath) 29 { 30 try 31 { 32 if (!string.IsNullOrEmpty(filePath)) 33 { 34 _xmlDoc.Load(filePath); 35 } 36 } 37 catch (Exception ex) 38 { 39 throw ex; 40 } 41 } 42 43 #endregion 44 45 #region 得到数据表 46 47 /// <summary> 48 /// 得到节点数据表 49 /// </summary> 50 /// <returns></returns> 51 public DataView GetNodeData(string tagName) 52 { 53 DataSet ds = null; 54 XmlNodeList nodeList = _xmlDoc.GetElementsByTagName(tagName); 55 if (nodeList == null || nodeList.Count == 0) 56 { 57 return null; 58 } 59 else 60 { 61 ds = new DataSet(); 62 XmlNode node = nodeList[0]; 63 StringReader reader = new StringReader(node.OuterXml); 64 ds.ReadXml(reader); 65 return ds.Tables[0].DefaultView; 66 } 67 } 68 69 #endregion 70 }
3.定义一个LocalizeByXMLFile,实现当语言切换时，能自动获取到当前语言的文本信息
1 public class LocalizeByXMLFile 2 { 3 private string _languageXMLPath = string.Empty; 4 private string _languageTagName = string.Empty; 5 private string _languageCode = string.Empty; 6 private DataRow _resource = null; 7 8 public LocalizeByXMLFile(string languageXMLPath,string languageTagName) 9 { 10 _languageXMLPath = languageXMLPath; 11 _languageTagName = languageTagName; 12 } 13 14 /// <summary> 15 /// Load data from xmlPath 16 /// </summary> 17 /// <param name="languageXMLPath"></param> 18 private void LoadResource(string languageXMLPath) 19 { 20 XMLHealper xh = new XMLHealper(languageXMLPath); 21 DataView dv = xh.GetNodeData(_languageTagName); 22 _resource = dv[0].Row; 23 } 24 25 /// <summary> 26 /// 判断当前的语言是否与CurrentUICulture相同，如果不同，则需要重新加载XML Data 27 /// </summary> 28 public DataRow Resource 29 { 30 get 31 { 32 string currentLanguageCode = Thread.CurrentThread.CurrentUICulture.Name; 33 if(_languageCode != currentLanguageCode) 34 { 35 _languageCode = currentLanguageCode; 36 string specialLanguageXMLPath = _languageXMLPath.Insert(_languageXMLPath.LastIndexOf(".") + 1, currentLanguageCode + "."); 37 LoadResource(specialLanguageXMLPath); 38 } 39 return _resource; 40 } 41 set 42 { 43 _resource = value; 44 } 45 } 46 47 /// <summary> 48 /// 获取对应语言的消息 49 /// </summary> 50 /// <param name="str"></param> 51 /// <returns></returns> 52 public string GetMsg(string str) 53 { 54 string val = ""; 55 try 56 { 57 val = Resource[str].ToString(); 58 } 59 catch 60 { 61 // "Cannot Found:" + strId + " , Please Add it to Resource File."; 62 } 63 return val; 64 } 65 }
4.使用LocalizeByXMLFile来实现多语言
1 private LocalizeByXMLFile _localize = new LocalizeByXMLFile(@"LanguageResources\Language.xml", "language"); 2 localizeByXMLFile.GetMsg("key");
三、在特定的项目中如何实现多语言
1.对于WPF项目而言，可以直接在xaml文件中使用Binding来实现Text的多语言切换，如<TextBox Text = {binding LanguageResource["txtKey"]}>
2.对于WinForm项目可言，UI的多语言的实现可以稍麻烦一点，可实现一个类来遍历UI中的所有元素，然后然后languageResource的getString()来设置UI的文本。
1 public class LocalizeForm : LocalizeByXMLFile 2 { 3 public LocalizeForm(string languageXMLPath, string languageTagName) 4 :base(languageXMLPath,languageTagName) 5 { 6 7 } 8 9 public void FormatUI(System.Windows.Forms.Control control) 10 { 11 control.Text = GetMsg(control.Name); 12 for (int i = 0; i < control.Controls.Count; i++) 13 { 14 switch (control.Controls[i].GetType().Name) 15 { 16 case "Label": 17 case "Button": 18 case "CheckBox": 19 case "RadioButton": 20 case "LinkLabel": 21 case "ToolStripMenuItem": 22 control.Controls[i].Text = GetMsg(control.Controls[i].Name); 23 break; 24 case "Panel": 25 case "GroupBox": 26 case "TableLayoutPanel": 27 case "FlowLayoutPanel": 28 FormatUI(control.Controls[i]); 29 break; 30 case "MenuStrip": 31 MenuStrip msp = (MenuStrip)control.Controls[i]; 32 foreach (ToolStripMenuItem n in msp.Items) 33 { 34 FormatMenuItem(n); 35 } 36 break; 37 case "TabControl": 38 TabControl tbc = (TabControl)control.Controls[i]; 39 for (int j = 0; j < tbc.TabCount; j++) 40 { 41 tbc.TabPages[j].Text = GetMsg(tbc.TabPages[j].Name); 42 FormatUI(tbc.TabPages[j]); 43 } 44 break; 45 default: 46 break; 47 } 48 } 49 } 50 51 /// <summary> 52 /// 匹配ToolStripMenuItem 53 /// </summary> 54 /// <param name="menuItem"></param> 55 private void FormatMenuItem(ToolStripMenuItem menuItem) 56 { 57 if (menuItem.HasDropDownItems == false) 58 { 59 menuItem.Text = GetMsg(menuItem.Name); 60 } 61 else 62 { 63 for (int i = 0; i < menuItem.DropDownItems.Count; i++) 64 { 65 if (menuItem.DropDownItems[i] is ToolStripSeparator) 66 { 67 continue; 68 } 69 else 70 { 71 FormatMenuItem((ToolStripMenuItem)menuItem.DropDownItems[i]); 72 } 73 } 74 } 75 } 76 }
然后在Form.cs中直接调用如下代码
/// <summarys> /// <summary> /// 1.通过资源文件来设置多语言 /// </summary> /// <summary> /// 2.通过加载XML文件来设置多语言 /// </summary> /// </summarys> public partial class ApplyResourceFile : Form { /* private ResourceManager _resouceManager = null; public ApplyResourceFile() { InitializeComponent(); } public override void LoadResource() { _resouceManager = new ResourceManager("LocalizeWinForm.LanguageResources.Language", typeof(ApplyResourceFile).Assembly); } /// <summary> /// 通过资源文件来设置多语言 /// </summary> /// <param name="str"></param> /// <returns></returns> public override string GetMsg(string str) { return _resouceManager.GetString(str); } private void rb_English_CheckedChanged(object sender, EventArgs e) { CultureInfo cultureInfo = null; if (rb_English.Checked) { cultureInfo = new System.Globalization.CultureInfo("en-GB"); } else { cultureInfo = new System.Globalization.CultureInfo("zh-Hans"); } SetLanguage(cultureInfo); } */ private LocalizeByXMLFile _localize = new LocalizeByXMLFile(@"LanguageResources\Language.xml", "language"); private LocalizeForm _localizeForm = new LocalizeForm(@"LanguageResources\Language.xml", "language"); public ApplyResourceFile() { InitializeComponent(); } private void rb_English_CheckedChanged(object sender, EventArgs e) { if (rb_English.Checked) { Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("en-GB"); } else { Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("zh-Hans"); } } private void ApplyResourceFile_Load(object sender, EventArgs e) { _localizeForm.FormatUI(this); } private void btn_Ok_Click(object sender, EventArgs e) { Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("zh-Hans"); _localizeForm.FormatUI(this); } }
