C# DataGridView 打印代码
初衷：由于之前遇到了这个问题 在网上搜索了许久 才把代码给调试好了 感觉 有必要 自己整理一下 方便“在路上”的IT们……
//打印按钮为:button6
//命名空间：（只能比我的多，不能比我的少，有时候 会忘记这个最重要的地方，这是最…的…）
//三个控件：

using System.ComponentModel;

using System.Windows.Forms;

using System.Drawing.Printing;
//第一种：

printPreviewDialog1.ClientSize = new System.Drawing.Size(800, 500);//设置打印预览时的页面大小
printPreviewDialog1.PrintPreviewControl.Zoom = 1; //显示百分比为 100%
printPreviewDialog1.ShowDialog();
}
else
{
MessageBox.Show("打印内容为空");
}
}

{

{
e.Graphics.DrawString(dataGridView1.Rows[i].Cells[j].Value.ToString(), new Font("宋体", 8, FontStyle.Regular), Brushes.Black, r, c);
