如何从UserControl获取数据以形成表单？C#WinForms和SQLite

我知道有人问过这个问题，但不幸的是，大多数答案并没有解决问题。所以希望有人能帮我：）

这就是我的问题

我想从StudentLedgerControl获取这些数据（我用红色包围了它）。然后将此数据传输到名为StudentLedgerWindow的表单中

尽管在此之前，必须单击一个按钮来显示StudentLedgerWindow，一旦显示，传输的数据就会出现

StudentLedgerControl.cs

public void LoadStudentLedger(SQLiteConnection conn)
{
        SQLiteCommand sqlite_cmd;

        sqlite_cmd = new SQLiteCommand("SELECT * FROM Student", conn);
        SQLiteDataReader read = sqlite_cmd.ExecuteReader();

        StudentFlowPanel.SuspendLayout();
        StudentFlowPanel.Controls.Clear();

        while (read.Read())
        {
            sc = new StudentControl();
            sc.StudentIDLabel.Text = "Student ID: " + read.GetInt32(0).ToString(); // id
            sc.StudentNameLabel.Text = read.GetString(1) + " " + read.GetString(2) + " " + read.GetString(3); // fullname
            sc.StudentSectionLabel.Text = "Section: " + read.GetString(4); // section  
            sc.StudentLevelLabel.Text = "Level: " + read.GetInt32(5).ToString(); // level
            StudentFlowPanel.Controls.Add(sc);
        }
        
        
        StudentFlowPanel.ResumeLayout();  
}

    public string _StudentName;
    public string _StudentSection;
    public string _StudentLevel;
    public string _StudentId;

    public string StudentName
    {
        get { return _StudentName; }
        set { _StudentName = value; }
    }
    public string StudentSection
    {
        get { return _StudentSection; }
        set { _StudentSection = value; }
    }
    public string StudentLevel
    {
        get { return _StudentLevel; }
        set { _StudentLevel = value; }
    }
    public string StudentId
    {
        get { return _StudentId; }
        set { _StudentId = value; }
    }

StudentLedgerWindows（预期结果）

显示窗口按钮事件和用户界面

private void ViewLedgerButton_Click(object sender, EventArgs e)
{
    // Once clicked, the data should show on StudentLedgerWindow
}

public void LoadStudentLedger(SQLiteConnection conn)
    {
        SQLiteCommand sqlite_cmd;

        sqlite_cmd = new SQLiteCommand("SELECT * FROM Student", conn);
        SQLiteDataReader read = sqlite_cmd.ExecuteReader();

        StudentFlowPanel.SuspendLayout();
        StudentFlowPanel.Controls.Clear();

        while (read.Read())
        {
            sc = new StudentControl();
            sc.StudentIDLabel.Text = "Student ID: " + read.GetInt32(0).ToString(); // id
            sc.StudentNameLabel.Text = read.GetString(1) + " " + read.GetString(2) + " " + read.GetString(3); // fullname
            sc.StudentSectionLabel.Text = "Section: " + read.GetString(4); // section  
            sc.StudentLevelLabel.Text = "Level: " + read.GetInt32(5).ToString(); // level

            StudentFlowPanel.Controls.Add(sc);
        }

        StudentFlowPanel.ResumeLayout();
    }

public void LoadStudentLedger(SQLiteConnection conn)
    {
        SQLiteCommand sqlite_cmd;

        sqlite_cmd = new SQLiteCommand("SELECT * FROM Student", conn);
        SQLiteDataReader read = sqlite_cmd.ExecuteReader();

        StudentFlowPanel.SuspendLayout();
        StudentFlowPanel.Controls.Clear();

        while (read.Read())
        {
            sc = new StudentControl();
            sc.StudentId = "Student ID: " + read.GetInt32(0).ToString(); // id
            sc.StudentName = read.GetString(1) + " " + read.GetString(2) + " " + read.GetString(3); // fullname
            sc.StudentSection = "Section: " + read.GetString(4); // section  
            sc.StudentLevel = "Level: " + read.GetInt32(5).ToString(); // level

            sc.StudentIDLabel.Text = "Student ID: " + read.GetInt32(0).ToString(); // id
            sc.StudentNameLabel.Text = read.GetString(1) + " " + read.GetString(2) + " " + read.GetString(3); // fullname
            sc.StudentSectionLabel.Text = "Section: " + read.GetString(4); // section  
            sc.StudentLevelLabel.Text = "Level: " + read.GetInt32(5).ToString(); // level

            StudentFlowPanel.Controls.Add(sc);
        }

        StudentFlowPanel.ResumeLayout();
    }

提前感谢：）

另外，我是新来的，所以如果我的帖子有任何问题，请告诉我，以便我可以更改它。

我想我已经解决了。。。idk可能

我所做的就是创建getter和setter（kek，我应该先试试这个）

然后打电话给接受者和接受者。（如果这是有道理的，希望是有道理的）

旧代码

private void ViewLedgerButton_Click(object sender, EventArgs e)
{
    // Once clicked, the data should show on StudentLedgerWindow
}

public void LoadStudentLedger(SQLiteConnection conn)
    {
        SQLiteCommand sqlite_cmd;

        sqlite_cmd = new SQLiteCommand("SELECT * FROM Student", conn);
        SQLiteDataReader read = sqlite_cmd.ExecuteReader();

        StudentFlowPanel.SuspendLayout();
        StudentFlowPanel.Controls.Clear();

        while (read.Read())
        {
            sc = new StudentControl();
            sc.StudentIDLabel.Text = "Student ID: " + read.GetInt32(0).ToString(); // id
            sc.StudentNameLabel.Text = read.GetString(1) + " " + read.GetString(2) + " " + read.GetString(3); // fullname

            StudentFlowPanel.Controls.Add(sc);

        StudentFlowPanel.ResumeLayout();
    }

新代码

private void ViewLedgerButton_Click(object sender, EventArgs e)
{
    // Once clicked, the data should show on StudentLedgerWindow

        StudentFlowPanel.ResumeLayout();
    }

能手和二传手

public void LoadStudentLedger(SQLiteConnection conn)
{
        SQLiteCommand sqlite_cmd;

        sqlite_cmd = new SQLiteCommand("SELECT * FROM Student", conn);
        SQLiteDataReader read = sqlite_cmd.ExecuteReader();

        StudentFlowPanel.SuspendLayout();
        StudentFlowPanel.Controls.Clear();

        while (read.Read())
        {
            sc = new StudentControl();
            sc.StudentIDLabel.Text = "Student ID: " + read.GetInt32(0).ToString(); // id
            sc.StudentNameLabel.Text = read.GetString(1) + " " + read.GetString(2) + " " + read.GetString(3); // fullname
            sc.StudentSectionLabel.Text = "Section: " + read.GetString(4); // section  
            sc.StudentLevelLabel.Text = "Level: " + read.GetInt32(5).ToString(); // level
            StudentFlowPanel.Controls.Add(sc);
        }
        
        
        StudentFlowPanel.ResumeLayout();  
}

    public string _StudentName;
    public string _StudentSection;
    public string _StudentLevel;
    public string _StudentId;

    public string StudentName
    {
        get { return _StudentName; }
        set { _StudentName = value; }
    }
    public string StudentSection
    {
        get { return _StudentSection; }
        set { _StudentSection = value; }
    }
    public string StudentLevel
    {
        get { return _StudentLevel; }
        set { _StudentLevel = value; }
    }
    public string StudentId
    {
        get { return _StudentId; }
        set { _StudentId = value; }
    }

另外，如果我能做任何代码改进，请告诉我：）

恐怕这里不接受代码图片，其中一个关键原因是：我们无法调试图像！请在您的问题中以文本形式提供您的代码。好的，我的错。对不起，您的问题到底是什么？我想从usercontrol获取表单中的数据。
