如何使用IronPython结合Windows.Forms实现Visual Basic输入框功能

内置输入框存在性说明 #

原生.NET WinForms类库未提供开箱即用的输入对话框组件，确实需要基于TextBox、Button、Form等基础控件自定义实现。

IronPython 实现代码示例 #

完整封装代码 #

import clr
clr.AddReference("System.Windows.Forms")
clr.AddReference("System.Drawing")

from System.Windows.Forms import (
    Form, Label, TextBox, Button, DialogResult, 
    FormBorderStyle, StartPosition, Padding
)
from System.Drawing import Size, Point

class InputBox(Form):
    def __init__(self, title, prompt, default_value=""):
        # 基础窗体配置
        self.Text = title
        self.Size = Size(380, 180)
        self.FormBorderStyle = FormBorderStyle.FixedDialog
        self.StartPosition = StartPosition.CenterScreen
        self.MinimizeBox = False
        self.MaximizeBox = False
        self.Padding = Padding(10)
        
        # 提示文本标签
        self.label = Label()
        self.label.Text = prompt
        self.label.Location = Point(10, 10)
        self.label.Size = Size(340, 20)
        self.Controls.Add(self.label)
        
        # 输入文本框
        self.textbox = TextBox()
        self.textbox.Location = Point(10, 40)
        self.textbox.Size = Size(340, 20)
        self.textbox.Text = default_value
        self.Controls.Add(self.textbox)
        
        # OK按钮
        self.btn_ok = Button()
        self.btn_ok.Text = "OK"
        self.btn_ok.DialogResult = DialogResult.OK
        self.btn_ok.Location = Point(200, 80)
        self.btn_ok.Size = Size(75, 25)
        self.Controls.Add(self.btn_ok)
        self.AcceptButton = self.btn_ok
        
        # Cancel按钮
        self.btn_cancel = Button()
        self.btn_cancel.Text = "Cancel"
        self.btn_cancel.DialogResult = DialogResult.Cancel
        self.btn_cancel.Location = Point(280, 80)
        self.btn_cancel.Size = Size(75, 25)
        self.Controls.Add(self.btn_cancel)
        self.CancelButton = self.btn_cancel
    
    @staticmethod
    def Show(title, prompt, default_value=""):
        box = InputBox(title, prompt, default_value)
        result = box.ShowDialog()
        if result == DialogResult.OK:
            return box.textbox.Text
        return None

调用方法 #

直接调用静态方法Show即可，返回值为用户输入的文本（点击Cancel返回None）：

# 调用示例
user_input = InputBox.Show("输入框标题", "请输入你的内容：", "默认值")
if user_input is not None:
    print(f"用户输入的内容是：{user_input}")
