C#无法在TableLayoutPanel中动态均匀地自动调整列大小

我有一个WinForm，它有一个

TableLayoutPanel

控件。我的代码将检测屏幕上连接的监视器的数量，为每个监视器创建一列，然后在

TableLayoutControl

中的每个列中为每个显示添加一个按钮，因此我可以确保无论连接了多少监视器，按钮都将在整个表单中显示为“居中”。一个/两个监视器渲染得很好，但是三个监视器会导致端列分布不均匀

这是我的密码：

            int count = Screen.AllScreens.Count();
            this.monitorLayoutPanel.ColumnCount = count;

            ColumnStyle cs = new ColumnStyle(SizeType.Percent, 100 / count);
            this.monitorLayoutPanel.ColumnStyles.Add(cs);

            this.monitorLayoutPanel.AutoSize = true;

            var buttonSize = new Size(95, 75);

            int z = 0;
            foreach (var screen in Screen.AllScreens.OrderBy(i => i.Bounds.X))
            {

                Button monitor = new Button
                {
                    Name = "Monitor" + screen,
                    AutoSize = true,
                    Size = buttonSize,

                    BackgroundImageLayout = ImageLayout.Stretch,                                                  
                    BackgroundImage = Properties.Resources.display_enabled,
                    TextAlign = ContentAlignment.MiddleCenter,
                    Font = new Font("Segoe UI", 10, FontStyle.Bold),
                    ForeColor = Color.White,
                    BackColor = Color.Transparent,
                    Text = screen.Bounds.Width + "x" + screen.Bounds.Height,
                    Anchor = System.Windows.Forms.AnchorStyles.None
                };


                this.monitorLayoutPanel.Controls.Add(monitor, z, 0);
                z++;
                monitor.MouseClick += new MouseEventHandler(monitor_Click);
            }

我尝试过缩小按钮，增加表单大小，但最后一列总是比前两列小。我不明白

首先清除列样式

this.monitorLayoutPanel.ColumnStyles.Clear();

然后：

int count=Screen.AllScreens.count（）；
for（int i=0；i

将我指向这条线，它将我指向了正确的方向。更新（和工作）代码如下：

谢谢你的建议。它使最后两列更加均匀，但所有三列仍然分布不均匀：可能是因为float参数。@MSL是的，

ColumnStyles

应该首先清除。对于这个问题，我会将按钮列表放在表单的底部中心。若要使动态控件在表单的底部中心对齐，请查看第二个链接帖子。您可以将按钮控件添加到自动调整大小的

FlowLayoutPanel

，其锚定设置为

Top，Bottom

，并位于停靠到按钮

TableLayoutPanel

的单列中。如果对内容使用合适的锚定，则单个单元格

TableLayoutPanel

会将自动调整大小的内容保持在中心（例如

None

或

Top，Bottom

）：

int count = Screen.AllScreens.Count();

for (int i = 0; i < count; i++)
{
    ColumnStyle cs = new ColumnStyle(SizeType.Percent, (float)100 / count);
    this.monitorLayoutPanel.ColumnStyles.Add(cs);
}

this.monitorLayoutPanel.AutoSize = true;

...

            int screens = Screen.AllScreens.Count();
            this.monitorLayoutPanel.ColumnStyles.Clear();
            this.monitorLayoutPanel.ColumnCount = screens;            
            this.monitorLayoutPanel.AutoSize = true;

            int z = 0;
            foreach (var screen in Screen.AllScreens.OrderBy(i => i.Bounds.X))
            {
                var percent = 100f / screens;
                this.monitorLayoutPanel.ColumnStyles.Add(new ColumnStyle(SizeType.Percent, percent));

                Button monitor = new Button
                {
                    Name = "Monitor" + screen,
                    Size = new Size(95, 75),
                    BackgroundImageLayout = ImageLayout.Stretch,                                                  
                    BackgroundImage = Properties.Resources.display_enabled,
                    TextAlign = ContentAlignment.MiddleCenter,
                    Font = new Font("Segoe UI", 10, FontStyle.Bold),
                    ForeColor = Color.White,
                    BackColor = Color.Transparent,
                    Text = screen.Bounds.Width + "x" + screen.Bounds.Height,
                    Anchor = System.Windows.Forms.AnchorStyles.None
                };


                this.monitorLayoutPanel.Controls.Add(monitor, z, 0);
                z++;
                monitor.MouseClick += new MouseEventHandler(monitor_Click);
