篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了如何在c＃中只打印datagridview中的已检查行相关的知识，希望对你有一定的参考价值。
我有一个Datagridview它有一个checkboxcolumn！当数据加载为标准时，所有行都会被检查！但我需要取消选中其中一些和它们，将它的值发送到var并打印出来！
可能吗？
例如：
--------------------------------------------------------------
ColumnCheckBox | Column1 | Column2 | Column3
--------------------------------------------------------------
checked | 1251000014 | portraitx | U$ 125.00
checked | 1251000021 | notebooky | U$ 899.96
unchecked | 1265888512 | tabletx | U$ 899.96
checked | 1251444251 | iphoness | U$ 566.26
unchecked | 1255222142 | opticalreader | U$ 99.99
我想获取CHECKED行的值并发送到var并打印它！主要是...如何将此值发送到var？
提前致谢！
答案
Print all checked rows in a page:
private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
{
//Find all checked rows
var allCheckedRows = this.myDataGridView.Rows.Cast<DataGridViewRow>()
.Where(row => (bool?)row.Cells[0].Value == true)
.ToList();
//create a stringBuilder that will contain the string for all checked rows
var builder = new StringBuilder();
//For each checked row, create string presentation of row and add to output stringBuilder
allCheckedRows.ForEach(row =>
{
//Create an array of all cell value of a row to then concatenate them using a separator
var cellValues = row.Cells.Cast<DataGridViewCell>()
.Where(cell => cell.ColumnIndex > 0)
.Select(cell => string.Format("{0}", cell.Value))
.ToArray();
//Then joiconcatenate values using ", " as separator, and added to output
builder.AppendLine(string.Join(", ", cellValues));
//Here instead of adding them to the stringBuilder, you can add int to another list.
});
//Print the output string
e.Graphics.DrawString(builder.ToString(),
this.myDataGridView.Font,
new SolidBrush(this.myDataGridView.ForeColor),
new RectangleF(0, 0, this.printDocument1.DefaultPageSettings.PrintableArea.Width, this.printDocument1.DefaultPageSettings.PrintableArea.Height));
}
输出：
1251000014, portraitx, U$ 125.00
1251000021, notebooky, U$ 899.96
1251444251, iphoness, U$ 566.26
Print each checked row in a separate page:
private int currentPrintingRowIndex = 0;
private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
{
var allCheckedRows = this.myDataGridView.Rows.Cast<DataGridViewRow>()
.Where(row => (bool?)row.Cells[0].Value == true)
.ToList();
if (allCheckedRows.Count > currentPrintingRowIndex)
{
var builder = new StringBuilder();
var currentCheckedRow = allCheckedRows[currentPrintingRowIndex];
var cellValues = currentCheckedRow.Cells.Cast<DataGridViewCell>()
.Where(cell => cell.ColumnIndex > 0)
.Select(cell => string.Format("{0}", cell.Value))
.ToArray();
builder.AppendLine(string.Join(", ", cellValues));
e.Graphics.DrawString(builder.ToString(),
this.myDataGridView.Font,
new SolidBrush(this.myDataGridView.ForeColor),
new RectangleF(0, 0, this.printDocument1.DefaultPageSettings.PrintableArea.Width, this.printDocument1.DefaultPageSettings.PrintableArea.Height));
currentPrintingRowIndex += 1;
e.HasMorePages = allCheckedRows.Count > currentPrintingRowIndex;
}
}
输出：
一份3页的文件：
Page1 content: 1251000014, portraitx, U$ 125.00
Page2 content: 1251000021, notebooky, U$ 899.96
Page3 content: 1251444251, iphoness, U$ 566.26

****这是有关Reza Aghaei的有用代码的最终法典****
private int currentPrintingRowIndex = 0;
private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)

var allCheckedRows = this.dgv1.Rows.Cast<DataGridViewRow>()

var builder = new StringBuilder();
var currentCheckedRow = allCheckedRows[currentPrintingRowIndex];
var cellValues = currentCheckedRow.Cells.Cast<DataGridViewCell>()
.Where(cell => cell.ColumnIndex > 0)
.Select(cell => string.Format("{0}", cell.Value))
.ToArray();
builder.Append(string.Join(",", cellValues));
// begin of the aditional implementation
string ldp = builder.ToString();
string[] cadaum = ldp.Split(',');
var cents = cadaum[3].Substring(0, 2);
var descr = cadaum[1].ToString();
if (descr.Length >= 30)
{
var descr2 = descr.Substring(0, 30);
var descr3 = descr.Substring(30);
// end of the aditional implementation
// begin modification
