c# - 表格启动后如何更新？

Question

winform启动后是否可以更新

例如。

import clr
clr.AddReference("System")
clr.AddReference("System.Windows.Forms")
from System.Windows.Forms import (Application, Form, StatusBar)

form = Form()
form.sb = StatusBar()
form.sb.Parent = form
form.sb.Text = "Demo"
Application.Run(form)
form.sb.Text = "Test"

我能看到“演示”但看不到“测试”。

Application.Run后如何改变状态栏？

Answer 1

只需在加载事件中添加代码

 private void Form_Load(object sender, EventArgs e)
    {
       sb.Text = "Test";
      Application.DoEvents();
    }

调用 do 事件以强制重绘表单。

VB

Private Sub Form_Load(Byval Sender As Object, Byval e As EventArgs)
      sb.Text = "Test"
      Application.DoEvents()
End Sub
