c# - 以编程方式创建 GroupBox 并在其中添加标签

Question

我想以编程方式创建一个组框，并在其中放置标签。现在我创建了这个，但经过设计，我有这样的:

我正在尝试，但我不知道如何将标签分配到正确的位置以及如何将其分配给特定的组框

GroupBox groupBox1 = new GroupBox();
Panel grid1 = new Panel();
Label lbl1 = new Label { Text = "Completed" };
Label lbl2 = new Label { Text = "label" };
Label lbl3 = new Label { Text = "In progress" };
Label lbl4 = new Label { Text = "label" };
//etcetera
groupBox1.Width = 185;
groupBox1.Height = 160;
grid1.Height = 185;
grid1.Width = 160;

我怎样才能实现这一目标？问候 更新

正如下面的评论，我尝试

GroupBox groupBox1 = new GroupBox();
                    this.Controls.Add(groupBox1);
                    Panel grid1 = new Panel();
                    groupBox1.Controls.Add(grid1);
                    groupBox1.Location = new Point(20, 250);
                    grid1.Location = new Point(20, 250);
                    Label lbl1 = new Label { Text = "test" };
                    Label lbl2 = new Label { Text = "Test2" };
                    groupBox1.Name = "TESTTT";
                    groupBox1.Width = 222;
                    groupBox1.Height = 149;

                    grid1.Height = 218;
                    grid1.Width = 145;
                    grid1.Controls.Add(lbl1);
                    grid1.Controls.Add(lbl2);

结果:

但是我的组框只是清除，没有名称和标签，为什么会发生这种情况？

WinForms 中的控件经过排列，以便它们位于彼此内部。因此，您的 Form 有一个 Controls 集合，它本质上是 Control 类型的 Collection。因此，如果将 GroupBox 添加到表单，则必须将其添加到表单的 Controls 集合中。然后，如果您将控件添加到 GroupBox 中，则需要将其添加到 GroupBox 控件集合中。

考虑到这一点，您可以执行以下操作:

private void AddGroupBoxAndLables()
{
    GroupBox groupBox1 = new GroupBox();
    groupBox1.SetBounds(50, 50, 300, 200);
    this.Controls.Add(groupBox1);

    Label lblCompleted = new Label { Name = "lblCompleted", Text = "Completed" };
    lblCompleted.Location = new Point(20, 20);
    groupBox1.Controls.Add(lblCompleted);
    Label valCompleted = new Label { Name = "valCompleted" };
    valCompleted.Location = new Point(80, 20);
    groupBox1.Controls.Add(valCompleted);

    Label lblInProgress = new Label { Name = "lblInProgress", Text = "In Progress" };
    lblInProgress.Location = new Point(20, 60);
    groupBox1.Controls.Add(lblInProgress);
    Label valInProgress = new Label { Name = "valInProgress" };
    valInProgress.Location = new Point(80, 60);
    groupBox1.Controls.Add(valInProgress);
}
