[C#.NET][Winform] 文化特性 - 多國語言訊息方塊 / UI Culture–Multiple Languages MessageBox

上篇提到用資源檔來建立多語系的應用程式 [C#.NET][Winform] 文化特性 - 多國語言應用程式 / UI Culture - Multiple Languages Application，這次我想把訊息對話視窗也擺在資源檔內

UI規劃如下

分別依序建立好資源檔內的資料

 

加入以下程式碼

string[] _language = new[] { "en-us","zh-tw"};

ResourceManager _localResource = null;

private ComponentResourceManager _ResourceManager = new ComponentResourceManager();



private void button1_Click(object sender, EventArgs e)

{

    string name = this._localResource.GetString("Name");

    string data = this._localResource.GetString("Data");

    if (!string.IsNullOrEmpty(name) && !string.IsNullOrEmpty(data))

    {

        MessageBox.Show(string.Format(data, name));

    }

}



private void Form1_Load(object sender, EventArgs e)

{

    this._localResource = new ResourceManager("ResourceTest.Form1",Assembly.GetExecutingAssembly());

    this._localResource.IgnoreCase = false;

    this.comboBox1.Text = _language[0];

    this.comboBox1.DataSource = this._language;

}



public void CreateResourceManager(Control Control, string Language)

{

    CultureInfo info = new System.Globalization.CultureInfo(Language);

    Thread.CurrentThread.CurrentUICulture = info;//變更文化特性

    this._ResourceManager = new ComponentResourceManager(Control.GetType());

    this._ResourceManager.ApplyResources(Control, "$this");

    this.ApplyForm(Control);

}



public void ApplyForm(Control control)

{

    foreach (Control ctrl in control.Controls)

    {

        this._ResourceManager.ApplyResources(ctrl, ctrl.Name);

        if (ctrl.HasChildren)

        {

            ApplyForm(ctrl);

        }

    }

}



//切換語系

private void comboBox1_TextChanged(object sender, EventArgs e)

{

    comboBox1.TextChanged -= new EventHandler(comboBox1_TextChanged);

    CreateResourceManager(this, this.comboBox1.Text);

    comboBox1.TextChanged += new EventHandler(comboBox1_TextChanged);

}

執行結果如下

很好，一切都很順利，也成功的將訊息字串擺到資源檔裡

忘了如何存取資源檔的捧油參考上篇 [C#.NET][VB.NET] 如何取得資源檔 (ResourceManager) 的 資料 / 圖片

---

惡夢來了，當Winform表單裡有異動屬性時，剛剛所設定的訊息字串都會被VS給清掉

沒關係，換個角度思考，我把訊息建在別的資源檔總可以吧，分別建立資源檔Message.en-US.resx及Message.zh-TW.resx，並用資料夾裝起來，以免方案看起來凌亂

再將this._localResource改為正確的路徑即可，如此一來就不用擔心資源檔被VS清掉了

this._localResource = new ResourceManager("ResourceTest.MsgResources.Message", Assembly.GetExecutingAssembly());
