Question

我试图在一个从左到右的流动板中“愉快地”对齐控制顶部。

我有一个复选框和几个numericUpDowns。但是复选框始终在顶部有某种边距或填充。因此，我必须在numericUpDown的顶部添加margn以使它们排成一行。

这不太理想。为什么我不能让checkBox直接从flowpanel顶部开始，就像numericUpDown一样？

public partial class Form1 : Form
{
    public static FlowLayoutPanel ControlPanel;
    public void CreateControls()
    {
        ControlPanel = new FlowLayoutPanel();
        ControlPanel.SuspendLayout();
        ControlPanel.FlowDirection = FlowDirection.LeftToRight;
        ControlPanel.Height = 40;
        ControlPanel.Width = this.flowLayoutPanel1.Width - 10;
        ControlPanel.WrapContents = false;
        ControlPanel.AutoScroll = true;
        ControlPanel.Anchor = AnchorStyles.None;
        ControlPanel.BorderStyle = BorderStyle.FixedSingle;

        ControlPanel.Controls.Add(LabelWithText("LB", 60));

        AddNumericUpDown("Ledge", 20, 0, 1m, -500m, 500m);
        AddCheckBox("UseExit", "UseExit", false);
        AddNumericUpDown("WrongLedge", 30, 0, 1m, -500m, 500m);

        AddNumericUpDown("Max", 100000, 0, 100000m, 0m, 1000000m);

        ControlPanel.ResumeLayout();


        this.flowLayoutPanel1.Controls.Add(ControlPanel);

    }

    public Label LabelWithText(string text, int width)
    {
        Label label = new Label();
        label.Text = text;
        label.Width = width;
        label.Top = 0;
        return label;
    }

    public void AddCheckBox(string name, string text, bool initialValue)
    {
        CheckBox checkBox = new CheckBox();
        checkBox.Name = name;
        checkBox.Text = text;
        checkBox.Checked = initialValue;
        checkBox.Top = 0;
        checkBox.Margin = new Padding(5,0,0,0);
        checkBox.TextAlign = ContentAlignment.TopLeft;
        checkBox.CheckAlign = ContentAlignment.TopLeft;
        checkBox.ImageAlign = ContentAlignment.TopLeft;
        ControlPanel.Controls.Add(checkBox);
    }

    public void AddNumericUpDown(string name, double initialValue, int decimalPlaces, decimal increment, decimal minimum, decimal maximum)
    {
        NumericUpDown numericUpDown = new NumericUpDown();
        numericUpDown.DecimalPlaces = decimalPlaces;
        numericUpDown.Increment = increment;
        numericUpDown.Minimum = minimum;
        numericUpDown.Maximum = maximum;
        numericUpDown.Value = (decimal)initialValue;
        numericUpDown.Name = name;
        numericUpDown.Visible = true;
        numericUpDown.Margin = new Padding(2);
        numericUpDown.Top = 0;
        numericUpDown.Width = 80;
        ControlPanel.Controls.Add(LabelWithText(name, 70));
        ControlPanel.Controls.Add(numericUpDown);
    }
}

它不是应该对齐的上衣。文本的基线是应该在各种控件之间对齐的内容。如果你使用更大的字体，这一点就更明显了。
