大家好，我正在添加PictureBoxes到TableLayoutPanel单元格中，但是对于 10x10 网格，它需要 10 秒，这太长了。我的代码看起来像这样，你能告诉我如何改进它，所以PictureBoxes会立即添加吗？这是我的做法：
private void x10ToolStripMenuItem_Click(object sender, EventArgs e)
{
tableLayoutPanel1.Controls.Clear();
tableLayoutPanel1.ColumnStyles.Clear();
tableLayoutPanel1.RowStyles.Clear();
tableLayoutPanel1.ColumnCount = 10;
tableLayoutPanel1.RowCount = 10;
int sliderval = trackBar1.Value;
//tableLayoutPanel1.Controls.Add(new PictureBox(),2,1);
for (int i = 0; i < tableLayoutPanel1.RowCount; i++)
{
tableLayoutPanel1.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent, (100 / tableLayoutPanel1.RowCount)));
for (int j = 0; j < tableLayoutPanel1.ColumnCount; j++)
{
tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, (100 / tableLayoutPanel1.ColumnCount)));
PictureBox picture = new PictureBox
{
Name = "pictureBox" + i,
Size = new Size(49, 35),
Visible = true,
Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom)
| System.Windows.Forms.AnchorStyles.Left)
| System.Windows.Forms.AnchorStyles.Right))),
BackColor = colors[random.Next(0, sliderval)],
TabIndex = 0,
TabStop = false
};
tableLayoutPanel1.Controls.Add(picture, j, i);
picture.Dock = DockStyle.Fill;
// picture.Margin = new Thickness(40, 16, 0, 0);
// picture.Padding = new Padding(0);
picture.SizeMode = PictureBoxSizeMode.Normal;
picture.Margin = new Padding(0);
}
}
AssignClickEvent();
}
