在程序增加多语言功能

先做个广告:)

 

E-Label是一个专业条码标签打印软件.它会让条码标签打印变得更简单.更方便二次开发(.NET)

目前此软件在Beta阶段.如果你对些软件有兴趣可以到

http://www.ync-tech.com下截Beta版本

 

最近一直在开发E-Label,客户提出来了新需求,要支持简体中文,繁体中文,English切换.E-Label刚开发的时候没有考虑到多语言的问题.

 

后来想来想去,还是用xml+单件模式来完成语言切换,效果还不错:)。

 

 

下面我来给大家讲讲我是怎么实现的：
第一步:

产生控件列表xml,就不需要一个一个的手工组织了也是因为这个原因而没有采用资源文件的方式.

主要工作的是CreateFile函数;

//建立一个临时Dictionary存放要生成xml的控件

private Dictionary<string, string> temp = new Dictionary<string,string>();

private void BaseForm_Load(object sender, EventArgs e) { this.SuspendLayout(); //决断是否在运行状态 if (CommonSettings.RuntimeMode) { //加载控件的文本 LoadText(); } //创建相应控件列表格式为xml方式 //正式程序中需将些注释掉 CreateFile(); this.ResumeLayout(false); }

 

CreateFile:这个里面的代码都比较简单,我就不做解释了.

到这里大家可能会产生一个疑问.temp里的数据是从哪里来的?

temp里的数据是在LoadText()里来添加的

 private void CreateFile() { //如果有值则进行产生xml文件 if (temp.Count > 0) { //产生一个窗口里所有控件xml文件 StringBuilder sb = new StringBuilder(); sb.AppendLine(string.Format("<{0}>", this.Name)); sb.AppendLine(string.Format("<Text>{0}</Text>",this.Text)); foreach (KeyValuePair<string, string> key in temp) { if(!string.IsNullOrEmpty(key.Key)) sb.AppendLine(string.Format("<{0}>{1}</{2}>", key.Key, TranslateXml(key.Value), key.Key)); } sb.AppendLine(string.Format("</{0}>", this.Name)); FileStream fs = new FileStream(SWF.Application.StartupPath + "//Temp//" + this.Name + ".txt", FileMode.Create); StreamWriter sw = new StreamWriter(fs); sw.Write(sb.ToString()); sw.Close(); fs.Close(); } } private string TranslateXml(string oldString) { string retValue = oldString; retValue = retValue.Replace("&", "&"); retValue = retValue.Replace("<", "<"); retValue = retValue.Replace(">", ">"); retValue = retValue.Replace("'", "'"); retValue = retValue.Replace("/"", """); return retValue; }

 

LoadText:

  /// <summary> /// 多语言加载 /// </summary> public void LoadText() { //检查是不是在运行状态 if (CommonSettings.RuntimeMode) { //是指定了节点的值 if (string.IsNullOrEmpty(ParentNode)) { _parentNode = this.Name; } //获取设置form caption是值 /* * CommonSettings.LanguageInsance这个是一个静态单件,在程序运行和改变语言的时候 * 需要重新初始化. * 这块我就暂时不上来了,过几天我写个例子在一块就上来 */ string text = CommonSettings.LanguageInsance.GetText(ParentNode + "/Text"); if (!string.IsNullOrEmpty(text)) { this.Text = text ; if (this.Name == "frmP") { this.Text += "-Beta verison(20101018) http://www.ync-tech.com"; } } //获取窗体上所有控件 SWF.Control[] tempControls = new SWF.Control[this.Controls.Count]; this.Controls.CopyTo(tempControls, 0); //加载控件的text值 LoadControlText(tempControls); } }

 

LoadControlText:(主要处理都在这里)

根据控件ID来加载控件的Text.

/// <summary> /// 根据control ID 从配置文件中获取Text /// </summary> /// <param name="args"></param> private void LoadControlText(SWF.Control[] args) { foreach (SWF.Control control in args) { //剔除不需要加载的控件 if( control is SWF.TextBox || control is SWF.ComboBox || control is SWF.PictureBox || control is SWF.NumericUpDown || control is CustomControls.Control.NumberTextBox || control is CustomControls.Control.Ruler ) { continue; } //自定义控件 if (control is BaseUserControl) { (control as BaseUserControl).LoadText(); (control as BaseUserControl).LoadCustomerSettings(); continue; } //这个是我继承List写的一个控件就是截图右下角的那个List if (control is SWF.ListBox) { control.Invalidate(); continue; } //这个也是自定义控件 if (control is Designer) { control.Invalidate(); SWF.ContextMenuStrip cms = (control as Designer).cmMenu; List<SWF.ToolStripItem> items = new List<SWF.ToolStripItem>(); for (int i = 0; i < cms.Items.Count; i++) { if (cms.Items[i] is SWF.ToolStripMenuItem) { items.Add(cms.Items[i]); } } LoadControlText(items.ToArray()); continue; } //判断Control里是不是还有控件如果有话采用递归的方式来处理 if (control.Controls.Count > 0) { SWF.Control[] tempControls = new SWF.Control[control.Controls.Count]; control.Controls.CopyTo(tempControls, 0); LoadControlText(tempControls); } //自定义控件 if (control is RibbonTabControl) { RibbonTabControl tc = control as RibbonTabControl; RibbonTabPage[] tempControls = new RibbonTabPage[tc.Controls.Count]; for (int i = 0; i < tc.Controls.Count; i++) { tempControls[i] = tc.Controls[i] as RibbonTabPage; } LoadControlText(tempControls); } //处理菜单 else if (control is SWF.MenuStrip) { SWF.MenuStrip ms = control as SWF.MenuStrip; SWF.ToolStripMenuItem[] tempControls = new SWF.ToolStripMenuItem[ms.Items.Count]; ms.Items.CopyTo(tempControls, 0); LoadControlText(tempControls); } //处理toolbar else if (control is SWF.ToolStrip) { SWF.ToolStrip ts = control as SWF.ToolStrip; List<SWF.ToolStripButton> list = new List<SWF.ToolStripButton>(); foreach (object obj in ts.Items) { if (obj is SWF.ToolStripButton) { list.Add(obj as SWF.ToolStripButton); } } LoadControlText(list.ToArray()); } //自定义控件 else if (control is CustomControls.Control.DrawToolBox) { CustomControls.Control.DrawToolBox ts = control as CustomControls.Control.DrawToolBox; List<SWF.ToolStripButton> list = new List<SWF.ToolStripButton>(); foreach (object obj in ts.Items) { if (obj is SWF.ToolStripButton) { list.Add(obj as SWF.ToolStripButton); } } LoadControlText(list.ToArray()); } else if (control is SWF.DataGridView) { SWF.DataGridView gv = control as SWF.DataGridView; if (gv.ContextMenuStrip != null) { SWF.ToolStripItem[] items = new SWF.ToolStripItem[gv.ContextMenuStrip.Items.Count]; gv.ContextMenuStrip.Items.CopyTo(items, 0); LoadControlText(items); } } if (control is RibbonTabControl) { if ((control as RibbonTabControl).ShowDefaultButton) { string text = CommonSettings.LanguageInsance.GetText(ParentNode + "/" + control.Name + "_Button"); (control as RibbonTabControl).DefaultButtonText = text; } } else if(control is GlassButton) { string text = CommonSettings.LanguageInsance.GetText(ParentNode + "/" + control.Name); if (!string.IsNullOrEmpty(text)) { (control as GlassButton).Text = text; } } else { //常用用的控件 //如果是容器控件则不做任何处理 if (control is SWF.TableLayoutPanel || control is SWF.FlowLayoutPanel || string.IsNullOrEmpty(control.Name) || control is CustomControls.Control.DocumentSpace1) { continue; } //加载Text内容 string text = CommonSettings.LanguageInsance.GetText(ParentNode + "/" + control.Name); if (!string.IsNullOrEmpty(text)) { control.Text = text; } } //不需要产生xml的控件 if ((control is RibbonTabControl && !(control as RibbonTabControl).ShowDefaultButton) || string.IsNullOrEmpty(control.Text) || control is SWF.TableLayoutPanel || control is SWF.FlowLayoutPanel) { continue; } //添加到temp dictionary在产生xml文件时使用 if (!temp.ContainsKey(control.Name) && AddtoTempList) { if (!temp.ContainsKey(control.Name + "_Button") && control is RibbonTabControl) { temp.Add(control.Name + "_Button", (control as RibbonTabControl).DefaultButtonText); } else { temp.Add(control.Name, control.Text); } } } }

 

要说的也就是这个.

我这个都是放到baseForm里,在Load的时候进行加载.

 

产生的xml文件格式是

<frmALDateTime>
<Text>添加组合日期时间</Text>
<btnOk>确定(&amp;O)</btnOk>
<btnCancel>取消(&amp;C)</btnCancel>
<btnFormat>自定义格式(&amp;S)</btnFormat>
<groupBox16>所选格式预览</groupBox16>
<groupBox15>已定义日期格式</groupBox15>
</frmALDateTime>

 

好了就先介绍到这里,如有问题可以给我留言.

过二天我会做个例子跟大家分享.
