Facebook のように、言語を変更すると、すべてが変更されます。ここでコードを再構築するのに助けが必要です。3 つのフォームがあり、言語を選択するために使用したコンボボックスは最初のフォームにあります。最初のフォームのコンボボックスで言語を選択すると、他の 2 つのフォームもその言語を変更する必要があります。

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
    if (comboBox1.SelectedItem.ToString() == "English")
    {
        ChangeLanguage("en");
    }
    else if (comboBox1.SelectedItem.ToString() == "Spanish")
    {
        ChangeLanguage("es-ES");
    }
    else if (comboBox1.SelectedItem.ToString() == "French")
    {
        ChangeLanguage("fr-FR");
    }
}

private void ChangeLanguage(string lang)
{
    foreach (Control c in this.Controls)
    {
        ComponentResourceManager crm = new ComponentResourceManager(typeof(Form1));
        crm.ApplyResources(c, c.Name, new CultureInfo(lang));
    }
}

「LanguageChanged」の静的イベントを保持する基本クラスと、それをトリガーする関数を使用できます。すべてのフォームがその基本クラスの派生クラスである場合、イベントはその中で処理できます。何かのようなもの：

public partial class Form1 : BaseLanguageForm
{

    public Form1()
    {
        InitializeComponent();

    }

    private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (comboBox1.SelectedItem.ToString() == "English")
        {
            this.TriggerLanguageChange("en");
        }
        else if (comboBox1.SelectedItem.ToString() == "Spanish")
        {
            this.TriggerLanguageChange("es-ES");
        }
        else if (comboBox1.SelectedItem.ToString() == "French")
        {
            this.TriggerLanguageChange("fr-FR");
        }
    }


}

あなたの質問から私が理解したことに基づいてChangeLanguage(string lang)、他のフォームからも電話をかけようとしている場合、これは可能であると思います.

void を使用するTimerすべての変数と 2 つの変数を追加する必要があります。Form1 つ目は が他の 2 つのフォーム内で呼び出される必要があるboolかどうかを検出するために使用される で、2 つ目は言語を示す です。これらの 2 つの変数は、他の形式で制御できるようにする必要があります。ChangeLanguagestringpublicstatic

例

Form1.cs

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Globalization;

namespace NameSpaceGoesHere
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        public static bool _ChangeLanguage = false; //This will indicate if the void needs to be called
        public static string _Language = ""; //This will indicate our new language
        private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            ChangeLanguage("fr-FR");

        }

        private void ChangeLanguage(string lang)
        {
            foreach (Control c in this.Controls)
            {
                ComponentResourceManager crm = new ComponentResourceManager(typeof(Form1));
                crm.ApplyResources(c, c.Name, new CultureInfo(lang));
                _Language = lang; //Sets the language to lang
                _ChangeLanguage = true; //Indicates that the void needs to be called through the TWO other forms as well
            }
        }

    }
}

Form2.cs

                ChangeLanguage(Form1._Language); //Call the method
            }
        }
    }
}
