C# WinForm MessageBox自定义按键文本 COM组件版

c# 更改弹窗MessageBox按钮文字_c# messagebox.show 字体-CSDN博客

需要用到大佬上传到百度云盘的Hook类，在大佬给的例子的基础上改动了点。

应用时自己加GUID和ProgID。

组件实现：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;namespace HookMessageBox
{[ComVisible(true)][Guid("")]interface IHookMessageBox{[DispId(1)]void ReadBtnLanguage();[DispId(1)]DialogResult MessageBoxOKBtnShow(string text,string caption, MessageBoxIcon icon);[DispId(1)]DialogResult MessageBoxYesOrNoBtnShow(string text,string caption, MessageBoxIcon icon);[DispId(1)]DialogResult MessageBoxYesOrNoOrCancelBtnShow(string text,string caption, MessageBoxIcon icon);}[ComVisible(true)][Guid("")][ProgId("")]public class ClsHookMessageBox: IHookMessageBox{private string OKText { get; set; }private string YesText { get; set; }private string NoText { get; set; }private string CancelText { get; set; }public void ReadBtnLanguage(){OKText = "OK";YesText = "Yes";NoText = "No";CancelText = "Cancel";}public DialogResult MessageBoxOKBtnShow(string text,string caption,MessageBoxIcon icon=MessageBoxIcon.None){return HookMessageBoxShow(text:text, caption:caption,okText: OKText, icon:icon);}public DialogResult MessageBoxYesOrNoBtnShow(string text, string caption, MessageBoxIcon icon = MessageBoxIcon.None){return HookMessageBoxShow(text: text, caption: caption, yesText: YesText, noText: NoText, buttons:MessageBoxButtons.YesNo,icon: icon);}public DialogResult MessageBoxYesOrNoOrCancelBtnShow(string text, string caption, MessageBoxIcon icon = MessageBoxIcon.None){return HookMessageBoxShow(text: text, caption: caption, yesText: YesText, noText: NoText, cancelText: CancelText, buttons: MessageBoxButtons.YesNoCancel, icon: icon);}private DialogResult HookMessageBoxShow(string text, string caption, MessageBoxButtons buttons= MessageBoxButtons.OK, MessageBoxIcon icon = MessageBoxIcon.None,string okText="",string yesText = "", string noText = "", string cancelText = ""){var hook = new HookINCS.Hook();hook.OnMessageBoxShow += (s, mbe) =>{IntPtr hChildWnd = mbe.hChildWnd;int result;if (!string.IsNullOrEmpty(yesText) && HookINCS.Win32Api_Hook.GetDlgItem(hChildWnd, 6) != 0)//IDYES = 6{result = HookINCS.Win32Api_Hook.SetDlgItemTextA(hChildWnd, 6, $"{yesText}");}if (!string.IsNullOrEmpty(noText) && HookINCS.Win32Api_Hook.GetDlgItem(hChildWnd, 7) != 0)//IDNO = 7{result = HookINCS.Win32Api_Hook.SetDlgItemTextA(hChildWnd, 7, $"{noText}");}if (!string.IsNullOrEmpty(cancelText) && HookINCS.Win32Api_Hook.GetDlgItem(hChildWnd, 2) != 0)//IDCANCEL = 2{result = HookINCS.Win32Api_Hook.SetDlgItemTextA(hChildWnd, 2, $"{cancelText}");}if (!string.IsNullOrEmpty(okText) && HookINCS.Win32Api_Hook.GetDlgItem(hChildWnd, 1) != 0)//IDOK =  1{result = HookINCS.Win32Api_Hook.SetDlgItemTextA(hChildWnd, 1, $"{okText}");}};hook.InstallMessageBoxHook();DialogResult dialogResult = MessageBox.Show(text, caption, buttons, icon);hook.UninstallMessageBoxHook();//卸载钩子return dialogResult;}}
}

调用：

object obj = Activator.CreateInstance(Type.GetTypeFromProgID("HookMessageBox.ClsHookMessageBox"));
obj.GetType().GetMethod("ReadBtnLanguage").Invoke(obj, new object[] { });
DialogResult btn1=(DialogResult)obj.GetType().GetMethod("MessageBoxOKBtnShow").Invoke(obj, new object[] { "messageboxText", "messageCaption", MessageBoxIcon.None });
DialogResult btn2 = (DialogResult)obj.GetType().GetMethod("MessageBoxYesOrNoBtnShow").Invoke(obj, new object[] { "messageboxText", "messageCaption", MessageBoxIcon.None });
DialogResult btn3 = (DialogResult)obj.GetType().GetMethod("MessageBoxYesOrNoOrCancelBtnShow").Invoke(obj, new object[] { "messageboxText", "messageCaption", MessageBoxIcon.None });

效果：
