Winform下的语言国际化，几行代码轻松实现

   最近做了一些关于winform的项目，需要用到winform的语言国际化，在初使化的时候用起来非常方便。可以参考一下：

   

   核心逻辑：

OK，以下是核心代码和操作流程

一，添加LanguageHelper类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WFInfor
{
    public class LanguageHelper
    {

        #region SetAllLang
        /// <summary>
        /// Set language
        /// </summary>
        /// <param name="lang">language:zh-CN, en-US</param>
        private static void SetAllLang(string lang)
        {
            System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo(lang);
            Form frm = null;

            string name = "MainForm";

            frm = (Form)Assembly.Load("CameraTest").CreateInstance(name);

            if (frm != null)
            {
                System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager();
                resources.ApplyResources(frm, "$this");
                AppLang(frm, resources);
            }
        }
        #endregion

        #region SetLang
        /// <summary>
        /// 
        /// </summary>
        /// <param name="lang">language:zh-CN, en-US</param>
        /// <param name="form">the form you need to set</param>
        /// <param name="formType">the type of the form </param>
        public static void SetLang(string lang, Form form, Type formType)
        {
            System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo(lang);
            if (form != null)
            {
                System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(formType);
                resources.ApplyResources(form, "$this");
                AppLang(form, resources);
            }
        }
        #endregion

        #region AppLang for control
        /// <summary>
        ///  loop set the propery of the control
        /// </summary>
        /// <param name="control"></param>
        /// <param name="resources"></param>
        private static void AppLang(Control control, System.ComponentModel.ComponentResourceManager resources)
        {
            if (control is MenuStrip)
            {
                resources.ApplyResources(control, control.Name);
                MenuStrip ms = (MenuStrip)control;
                if (ms.Items.Count > 0)
                {
                    foreach (ToolStripMenuItem c in ms.Items)
                    {
                        AppLang(c, resources);
                    }
                }
            }

            foreach (Control c in control.Controls)
            {
                resources.ApplyResources(c, c.Name);
                AppLang(c, resources);
            }
        }
        #endregion

        #region AppLang for menuitem
        /// <summary>
        /// set the toolscript 
        /// </summary>
        /// <param name="item"></param>
        /// <param name="resources"></param>
        private static void AppLang(ToolStripMenuItem item, System.ComponentModel.ComponentResourceManager resources)
        {
            if (item is ToolStripMenuItem)
            {
                resources.ApplyResources(item, item.Name);
                ToolStripMenuItem tsmi = (ToolStripMenuItem)item;
                if (tsmi.DropDownItems.Count > 0)
                {
                    foreach (ToolStripMenuItem c in tsmi.DropDownItems)
                    {
                        AppLang(c, resources);
                    }
                }
            }
        }
        #endregion
    }
}

二，添加对应的资源文件（在文件夹下复制就可以了)

     注意：格式必须是  Form名.语言名.rexs

     我添加了两个，一个中文，一个英文

三，修改资源文件，添加需要切换语言的控件

中文资源文件修改：

英文资源文件修改：

四，调用代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Reflection;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WFInfor
{
    public partial class FrmMain : Form
    {
        public FrmMain()
        {
            InitializeComponent();
        }

        private void cbxchose_SelectedIndexChanged(object sender, EventArgs e)
        {
            if (cbxchose.SelectedItem.ToString() == "中文")
            {

                LanguageHelper.SetLang("zh-Cn", this, typeof(FrmMain));


            }

            else if (cbxchose.SelectedItem.ToString() == "English")
            {
                LanguageHelper.SetLang("en-Us", this, typeof(FrmMain));
            }
            else
            {
            }
        }
    }
