C#实现让ListBox适应最大Item宽度的方法

private void button1_Click(object sender, EventArgs e){ for (int i = 1; i <= 16; i++) {  listBox1.Items.Add("TTTTTTTTTTTTTTTTTTTTTTTTTTTTT" + i.ToString()); }}private void button2_Click(object sender, EventArgs e){ SizeF size = listBox1.CreateGraphics(). MeasureString(listBox1.Items[0].ToString(), listBox1.Font); MessageBox.Show(Convert.ToInt32(size.Width).ToString()); listBox1.Width = Convert.ToInt32(size.Width)+20;}
