我有一个dgv，我为产品添加了许多产品和代码，值等，然后我需要打印出内容。
最初，我使用此代码：
private int _Line = 0;
void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
Font myFont = new Font("Courier New", 08, FontStyle.Underline, GraphicsUnit.Point);
float lineHeight = myFont.GetHeight(e.Graphics) + 4;
float yLineTop = e.MarginBounds.Top;
int b = dataGridView1.Rows.Count;
for (int _Line = 0; _Line < b; _Line++)
{
if (yLineTop + lineHeight > e.MarginBounds.Bottom)
{
e.HasMorePages = true;
return;
}
//e.Graphics.DrawString("TEST: " + _Line, myFont, Brushes.Black,
// new PointF(e.MarginBounds.Left, yLineTop));
Graphics graphics = e.Graphics;
//Font font = new Font("Courier New", 8);
//float fontHeight = font.GetHeight();
int startX = 50;
int startY = 65;
int Offset = 40;
graphics.DrawString("Welcome to Bakery Shop - "+DateTime.Now+".", new Font("Courier New", 8), new SolidBrush(Color.Black), startX, startY + Offset);
Offset = Offset + 20;
string underLine = "------------------------------------------";
graphics.DrawString(underLine, new Font("Courier New", 8), new SolidBrush(Color.Black), startX, startY + Offset);
Offset = Offset + 20;
graphics.DrawString("" + label1.Text + "", new Font("Courier New", 10), new SolidBrush(Color.Black), startX, startY + Offset);
Offset = Offset + 20;
graphics.DrawString("Item", new Font("Courier New", 8), new SolidBrush(Color.Black), startX, startY + Offset);
graphics.DrawString("Cod.", new Font("Courier New", 8), new SolidBrush(Color.Black), startX+80, startY + Offset);
graphics.DrawString("Nome", new Font("Courier New", 8), new SolidBrush(Color.Black), startX + 160, startY + Offset);
graphics.DrawString("Valor", new Font("Courier New", 8), new SolidBrush(Color.Black), startX + 240, startY + Offset);
graphics.DrawString("Qtd.", new Font("Courier New", 8), new SolidBrush(Color.Black), startX + 320, startY + Offset);
graphics.DrawString("Parcial", new Font("Courier New", 8), new SolidBrush(Color.Black), startX + 400, startY + Offset);
graphics.DrawString("Desconto", new Font("Courier New", 8), new SolidBrush(Color.Black), startX + 510, startY + Offset);
graphics.DrawString("Subtotal", new Font("Courier New", 8), new SolidBrush(Color.Black), startX + 600, startY + Offset);
Offset = Offset + 20;
int a = dataGridView1.Rows.Count;
for (int i = 0; i < a; i++)
{
graphics.DrawString(Convert.ToString(dataGridView1.Rows[i].Index+1), new Font("Courier New", 8), new SolidBrush(Color.Black), startX, startY + Offset + 30);
graphics.DrawString("\t" + Convert.ToString(dataGridView1.Rows[i].Cells[0].Value), new Font("Courier New", 8), new SolidBrush(Color.Black), startX + 10, startY + Offset + 30);
graphics.DrawString("\t" + Convert.ToString(dataGridView1.Rows[i].Cells[1].Value), new Font("Courier New", 8), new SolidBrush(Color.Black), startX + 90, startY + Offset + 30);
graphics.DrawString("\t" + Convert.ToString(dataGridView1.Rows[i].Cells[2].Value), new Font("Courier New", 8), new SolidBrush(Color.Black), startX + 180, startY + Offset + 30);
graphics.DrawString("\t" + Convert.ToString(dataGridView1.Rows[i].Cells[3].Value), new Font("Courier New", 8), new SolidBrush(Color.Black), startX + 270, startY + Offset + 30);
graphics.DrawString("\t" + Convert.ToString(dataGridView1.Rows[i].Cells[4].Value), new Font("Courier New", 8), new SolidBrush(Color.Black), startX + 340, startY + Offset + 30);
graphics.DrawString("\t" + Convert.ToString(dataGridView1.Rows[i].Cells[5].Value), new Font("Courier New", 8), new SolidBrush(Color.Black), startX + 430, startY + Offset + 30);
graphics.DrawString("\t" + Convert.ToString(dataGridView1.Rows[i].Cells[6].Value), new Font("Courier New", 8), new SolidBrush(Color.Black), startX + 570, startY + Offset + 30);
Offset = Offset + 20;
graphics.DrawString("\t" +), new Font("Courier New", 8), new SolidBrush(Color.Black), startX + 570, startY + Offset + 30);
Offset = Offset + 20;
}
Offset = Offset + 20;
Offset = Offset + 20;
Offset = Offset + 20;
graphics.DrawString("Total - " + textBox7.Text + ".", new Font("Courier New", 8), new SolidBrush(Color.Black), startX, startY + Offset);
Offset = Offset + 20;
graphics.DrawString("Troco - " + textBox3.Text + ".", new Font("Courier New", 8), new SolidBrush(Color.Black), startX, startY + Offset);
Offset = Offset + 20;
yLineTop += lineHeight;
}
e.HasMorePages = false;
}
除了我稍后会工作的一些奇怪的行为，我注意到一行必须使每个元素很好地对齐，以便它不会在信息之上打印信息。
然后我想，如果我转换完整行并在每个单元格之间添加空格并打印数组，它将永远不会显示信息高于信息，即使例如＆＃34;代码＆＃34;太大了，所以它不会在＆＃34;名称＆＃34;上面显示/混合列。
这是更好的方法吗？我该如何开始制作呢？因为我看到的每个地方，解决方案是将单个单元格作为字符串传递。
就我而言，每一行都有6列，非常感谢！

修正如下：
int a = dataGridView1.Rows.Count;
for (int i = 0; i < a; i++)
{
string[] dgvtoarray = { Convert.ToString(dataGridView1.Rows[i].Index + 1), Convert.ToString(dataGridView1.Rows[i].Cells[0].Value), Convert.ToString(dataGridView1.Rows[i].Cells[1].Value), Convert.ToString(dataGridView1.Rows[i].Cells[2].Value), Convert.ToString(dataGridView1.Rows[i].Cells[3].Value), Convert.ToString(dataGridView1.Rows[i].Cells[4].Value), Convert.ToString(dataGridView1.Rows[i].Cells[5].Value), Convert.ToString(dataGridView1.Rows[i].Cells[6].Value) };
var result = string.Join(" | ", dgvtoarray);
graphics.DrawString(Convert.ToString(result), new Font("Courier New", 8), new SolidBrush(Color.Black), startX, startY + Offset + 30);
Offset = Offset + 20;
}

从datagridview打印的最佳方法是将数据传输到Excel工作表。
Microsoft.Office.Interop.Excel.Worksheet ws;
try
{
Microsoft.Office.Interop.Excel.Application Excell = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel.Workbook wb = Excell.Workbooks.Add(Microsoft.Office.Interop.Excel.XlSheetType.xlWorksheet);
ws = (Microsoft.Office.Interop.Excel.Worksheet)Excell.ActiveSheet;
Excell.Visible = true;
}
catch (Exception)
{
return;
}
int i = 1;
foreach (DataGridViewColumn clm in dgw.Columns)
{
ws.Cells[2, i] = clm.Name;
Microsoft.Office.Interop.Excel.Range xcell = ws.Cells[2, i];
Microsoft.Office.Interop.Excel.Borders brd1 = xcell.Borders;
xcell.HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignCenter;
brd1.LineStyle = Microsoft.Office.Interop.Excel.XlLineStyle.xlContinuous;
brd1.Weight = Microsoft.Office.Interop.Excel.XlBorderWeight.xlMedium;
i++;
}
Microsoft.Office.Interop.Excel.Range row = ws.Cells[2, i];
row.EntireRow.Font.Bold = true;
Microsoft.Office.Interop.Excel.Range fcell = ws.Cells[1, 1];
Microsoft.Office.Interop.Excel.Range lcell = ws.Cells[1, i - 1];
Microsoft.Office.Interop.Excel.Range space = ws.get_Range(fcell, lcell);
space.Merge(true);
space.EntireRow.Font.Bold = true;
ws.Cells[1, 1] = //Your text here
Microsoft.Office.Interop.Excel.Borders brd = space.Borders;
aralik.HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignCenter;
int m = 3;
foreach (DataGridViewRow rows in dgw.Rows)
{
for (int p = 1; p < i; p++)
{
if (rows.Cells[p-1].Value.ToString()=="")
{
string str = string.Empty;
foreach (Control item in cList)
{
if (item.Name=="lbl_"+(rows.Index.ToString())+"_"+((p-1).ToString()))
{
str = item.Text;
ws.Cells[m, p] = str;
}
}
}
else
{
ws.Cells[m, p] = rows.Cells[p - 1].Value;
}
}
m++;
}
ws.Columns.AutoFit();
这是我在学校考试申请中的代码。希望这会有所帮助。
