c#国际化

1.首先建立资源文件

LanguageDefine.xml

<?xml version="1.0" standalone="yes"?>
<Language>
  <DefaultLanguage>ZH</DefaultLanguage>
</Language>

设置默认语言

2.建立选择文件

AppConfig.xml

<?xml version="1.0" encoding="utf-8" ?>
<AppConfig>
  <Area>
    <Language>ZH</Language>
    <List>
      <Item>中文[ZH]</Item>
      <Item>英文[EN]</Item>
      
    </List>
  </Area>
  <Area>
    <Language>EN</Language>
    <List>
      <Item>Chinese[ZH]</Item>
      <Item>English[EN]</Item>
    </List>
  </Area>
</AppConfig>

选择中文还是英文

3.建立语言配置文件

AppResource_EN.xml

<?xml version="1.0" encoding="utf-8" ?>
<Resource>
  <Form>
    <Name>SwellInstrument</Name>
    <Controls>
      <Control name="SwellInstrument" text="SwellInstrument" />
      <Control name="Swe_label" text="Please double click on the select Swell Instrument" />
      <Control name="Swe_Line_Label" text="Port:" />
      <Control name="Swe_label1" text="Parity:" />
      <Control name="Swe_label3" text="Baud rate:" />
      <Control name="Swe_label2" text="Stop bit:" />
      <Control name="Swe_label5" text="Data bits:" />
      <Control name="Swe_label4" text="Handshake protocol" />
      <Control name="Swe_test" text="Test" />
      <Control name="Swe_confirm" text="Save" />
      <Control name="Swe_cancel" text="Cancel" />
    </Controls>

  </Form>


</Resource>

AppResource_ZH.xml

<?xml version="1.0" encoding="utf-8" ?>
<Resource>
  <Form>
    <Name>SwellInstrument</Name>
    <Controls>
      <Control name="SwellInstrument" text="涌浪仪" />
      <Control name="Swe_label" text="请双击选择涌浪仪" />
      <Control name="Swe_Line_Label" text="端口号:" />
      <Control name="Swe_label1" text="奇偶校验:" />
      <Control name="Swe_label3" text="波特率:" />
      <Control name="Swe_label2" text="停止位:" />
      <Control name="Swe_label5" text="数据位:" />
      <Control name="Swe_label4" text="握手协议:" />
      <Control name="Swe_test" text="测试" />
      <Control name="Swe_confirm" text="保存" />
      <Control name="Swe_cancel" text="取消" />
    </Controls>

  </Form>

</Resource>

5.设置下拉选择语言

 #region 国际化下拉取值
        private void ChooseLanguage_comboBox_SelectedIndexChanged(object sender, EventArgs e)
        {

            //获取combobox的值
            Global = ChooseLanguage_comboBox.SelectedItem.ToString();
            Global = Global.Trim();
            
            if (Global.IndexOf("-") == 0)
            {
                return;
            }
            else
            {
               
                Global = Global.Substring(Global.IndexOf("[") + 1, 2);
            }
            if (Global == "EN")
            {
                //ChooseLanguage_comboBox.SelectedIndexChanged -= new EventHandler(ChooseLanguage_comboBox_SelectedIndexChanged);
                ChooseLanguage_comboBox.Items.Clear();
               // ChooseLanguage_comboBox.Text = "English";
               
                International.WriteDefaultLanguage(Global);
                IList a = International.GetLanguageList(Global);
                            
                for (int i = 0; i < a.Count; i++)
                {
                    string aa = a[i].ToString();
                    aa=aa.Trim();                   
                    ChooseLanguage_comboBox.Items.Add(aa);
               
                 }

                ChooseLanguage_comboBox.SelectedIndex = 1;
              // ChooseLanguage_comboBox.SelectedIndex = -1;
              
            }
            else 
            {
               // ChooseLanguage_comboBox.SelectedIndexChanged -= new EventHandler(ChooseLanguage_comboBox_SelectedIndexChanged);
                ChooseLanguage_comboBox.Items.Clear();
                International.WriteDefaultLanguage("ZH");
                IList a = International.GetLanguageList(Global);
              
              //  ChooseLanguage_comboBox.Text = "ZH";
                for (int i = 0; i < a.Count; i++)
                {
                    string aa = a[i].ToString();
                    aa = aa.Trim();
                    ChooseLanguage_comboBox.Items.Add(aa);
                }
               // ChooseLanguage_comboBox.Text = ChooseLanguage_comboBox.Items[0].ToString();
                ChooseLanguage_comboBox.SelectedIndex = 0;
            }
           
        }
        //设置事件只发生一次
        private void ChooseLanguage_comboBox_SelectedValueChanged(object sender, EventArgs e)
        {
            string str = ChooseLanguage_comboBox.SelectedItem.ToString().Trim().Substring(ChooseLanguage_comboBox.SelectedItem.ToString().IndexOf("[") + 1, 2).ToUpper(); ;
            if (this.Global == str)
            {
                this.ChooseLanguage_comboBox.SelectedIndexChanged -= ChooseLanguage_comboBox_SelectedIndexChanged;
                this.axMapControl1.Focus();
            }
            else
            {
                this.ChooseLanguage_comboBox.SelectedIndexChanged += ChooseLanguage_comboBox_SelectedIndexChanged;
            }
        }
        #endregion

6.界面加载和关闭

    private void FormMain_Load(object sender, EventArgs e)
        {
            string stringa= "---请选择语言---";
            ChooseLanguage_comboBox.Items.Insert(0, stringa);
            ChooseLanguage_comboBox.Text = ChooseLanguage_comboBox.Items[0].ToString();
   
            Global = International.ReadDefaultLanguage();
            IList a = International.GetLanguageList(Global);
           
            for (int i = 0; i < a.Count; i++)
            {
                    string aa = a[i].ToString();
                    aa=aa.Trim();
                    ChooseLanguage_comboBox.Items.Add(aa);
               
            }
           
        }

        private void FormMain_FormClosed(object sender, FormClosedEventArgs e)
        {
            International.WriteDefaultLanguage("ZH");
        }
