推荐答案

此方式，您可以使用一些标准，发现一排，例如，你可以找到你首先检查行：

This way you can find a row using some criteria, for example you can find your first checked row:

var firstCheckedRow = this.myDataGridView.Rows.Cast<DataGridViewRow>() .Where(row => (bool?)row.Cells["MyCheckBoxColumn"].Value == true) .FirstOrDefault();

这样你就可以得到一个行的所有单元格的值，例如你可以把主题一起在一个字符串中的不同行：

This way you can get value of all cells of a row, for example you can put theme together in a string in different lines:

var builder = new StringBuilder(); firstCheckedRow.Cells.Cast<DataGridViewCell>() .ToList().ForEach(cell => { builder.AppendLine(string.Format("{0}", cell.Value)); });

然后就可以例如告诉他们：

Then you can for example show them:

MessageBox.Show（builder.ToString（））;

MessageBox.Show(builder.ToString());

甚至你可以把的PrintDocument 表单上，处理的PrintPage 事件来把它们打印到打印机。你还应该把按钮的形式和按钮的点击事件，调用 PrintDocument1.Print（）;

Or even you can put a PrintDocument on your form and handle PrintPage event to print them to printer. You also should put a Button on form and in click event of button, call PrintDocument1.Print();

code：

private void Button1_Click(object sender, EventArgs e) { PrintDocument1.Print(); } PrintDocument1_PrintPage(object sender, PrintPageEventArgs e) { var firstCheckedRow = this.myDataGridView.Rows.Cast<DataGridViewRow>() .Where(row => (bool?)row.Cells["MyCheckBoxColumn"].Value == true) .FirstOrDefault(); var builder = new StringBuilder(); firstCheckedRow.Cells.Cast<DataGridViewCell>() .ToList().ForEach(cell => { builder.AppendLine(string.Format("{0}", cell.Value)); }); e.Graphics.DrawString(builder.ToString(), this.myDataGridView.Font, new SolidBrush(this.myDataGridView.ForeColor), new RectangleF(0, 0, p.DefaultPageSettings.PrintableArea.Width, p.DefaultPageSettings.PrintableArea.Height)); }
