c# - 如何获得完美的边框并使窗口始终保持在顶部？

Question

我有这个 VB +WinForms 应用程序。 UI 如下图所示

添加/编辑 Material 窗口有自己独特的Aqua blue颜色边框。

后面的VB代码是

我已确保将这些行添加到我的 C# 代码的 Program.cs 文件中

static  class Program
    {
      [STAThread]
      static void Main()
      {
          Application.EnableVisualStyles();
          Application.SetCompatibleTextRenderingDefault(false);
          Mold_Power_Suite.View.frmMain mainForm = new frmMain();
         // WindowsFormsApplication3.view.Form1 abc = new view.Form1();
          Application.Run(mainForm);
      }
    }

1. 如何使应用程序和所有相应的弹出窗口看起来完全像它们在 VB 中的样子？
2. nee Windows 在不活动时往往落后于应用程序。我希望他们不要离开 Parent Window。

我该如何解决这些问题？

Answer 1

代替

MatRef.Show();

写

MatRef.ShowDialog();

如果那行不通，那么在此之前再添加一行

MatRef.TopLevel = false;

示例代码:

    /// </summary>
    /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
    protected override void Dispose(bool disposing)
    {
        if (disposing && (components != null))
