C# Windows 窗体自动关闭

我有一个 Windows 应用程序，其中我的第一个 Windows 窗体是登录。 成功登录后，必须打开“主页”表单。 我在调试时看到“Home”表单，但是一旦代码进入 Home.Designer.cs 中的 Dispose 方法，我的应用程序就会停止。

我的登录页面代码如下所示：

private void loginbtn_Click(object sender, EventArgs e)
{
        String username = "admin";
        String password = "admin";

        String @uname = Unametxtbox.Text;
        String @pass = Passtextbox.Text;

        if (@uname.Equals(username) && @pass.Equals(password))
        {                
            MessageBox.Show("Login Successful");                
            Home home = new Home();
            home.Show();
            this.Close();
        }
        else
        {
            MessageBox.Show("Invalid Credentials!");
        }
}

我的 Home.cs 页面如下所示：

public partial class Home : Form
{
    public Home()
    {
        InitializeComponent();
    }
} 

Home.Designer.cs 有以下代码：

partial class Home
{
    /// <summary>
    /// Required designer variable.
    /// </summary>
    private System.ComponentModel.IContainer components = null;

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

    #region Windows Form Designer generated code

    /// <summary>
    /// Required method for Designer support - do not modify
    /// the contents of this method with the code editor.
    /// </summary>
    private void InitializeComponent()
    {
        System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(Home));
        this.label1 = new System.Windows.Forms.Label();
        this.pictureBox1 = new System.Windows.Forms.PictureBox();
        this.closebtn = new System.Windows.Forms.PictureBox();
        this.groupBox1 = new System.Windows.Forms.GroupBox();
        this.Storedbtn = new System.Windows.Forms.Button();
        this.Soldbtn = new System.Windows.Forms.Button();
        this.Transbtn = new System.Windows.Forms.Button();
        this.Supbtn = new System.Windows.Forms.Button();
        this.Empbtn = new System.Windows.Forms.Button();
        this.Custbtn = new System.Windows.Forms.Button();
        ((System.ComponentModel.ISupportInitialize)(this.pictureBox1)).BeginInit();
        ((System.ComponentModel.ISupportInitialize)(this.closebtn)).BeginInit();
        this.groupBox1.SuspendLayout();
        this.SuspendLayout();
  }

    #endregion

    private System.Windows.Forms.Label label1;
    private System.Windows.Forms.PictureBox pictureBox1;
    private System.Windows.Forms.PictureBox closebtn;
    private System.Windows.Forms.GroupBox groupBox1;
    private System.Windows.Forms.Button Storedbtn;
    private System.Windows.Forms.Button Soldbtn;
    private System.Windows.Forms.Button Transbtn;
    private System.Windows.Forms.Button Supbtn;
    private System.Windows.Forms.Button Empbtn;
    private System.Windows.Forms.Button Custbtn;
}

如果我评论 this.Close();在loginbtn_Click中，我可以看到Windows窗体，但登录Windows窗体没有关闭。

我在这里缺少什么，提前致谢。

尝试使用隐藏而不是关闭。

Hide();
Home home = new Home();
home.ShowDialog();
Close();
