本文主要是介绍POS机的接口，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
联迪的POS机
读取付款方式
private void Form_MisPos_Load(object sender, EventArgs e)
{
List<Trans> list = MisPos.GetTransList();
int col = 0;
int y = 15;
int colcount = 3;
Panel p = panel3;
int pw = p.Width;
foreach (Trans t in list)
{
Button btn = new System.Windows.Forms.Button();
int x = col * (pw / 3) + 10;
btn.Location = new System.Drawing.Point(x, y);
btn.Name = "btn_" + t.Code;
btn.Size = new System.Drawing.Size(pw / 3 - 20, 28);
btn.Text = t.Text;
btn.UseVisualStyleBackColor = true;
btn.Click += new System.EventHandler(this.btn_Click);
p.Controls.Add(btn);
col++;
if (col >= colcount)
{
col = 0;
y = y + 32;
}
}
}
