barcodelib打印条码C#例子_barcodelib 打印 printpageeventargs-优快云博客

这段代码演示了如何在C#中利用barcodelib库生成并打印条码。首先引入必要的命名空间，然后在button1_Click事件中，创建条码图像，并使用PrintDocument进行打印。代码涉及到多个文件操作，用于生成和保存条码图像，最后通过DrawToBitmap方法将条码绘制到pictureBox上。

先引用barcodelib控件

using System.Drawing.Printing;

private void button1_Click(object sender, EventArgs e)

{
DialogResult result = MessageBox.Show("你确定要打印条码一？", "信息提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Information);

if (result == DialogResult.OK)
{
Control.CheckForIllegalCrossThreadCalls = false;
//打印次数
printDocument1.PrinterSettings.Copies = Convert.ToInt16(txt_print.Text.Trim());
//换成多线程方式
if (thre == null)
{
thre = new Thread(this.printDocument1.Print);
thre.Start();
}
if (thre.ThreadState == ThreadState.Stopped)
{
thre.Abort();
GC.Collect();
thre = new Thread(this.printDocument1.Print);
thre.Start();
}
}

}
