其中，要判断有几条收费，多一条就打印多一个，然后合计总价。
winform打印，没有这个显示的窗体 展开
1,在Form中加入一个印刷的控件PrintDocument，取名为MyPrintDocument
2,新建一个一般类（不是窗体类），名叫MyPrinter，内容如下：
public class MyPrinter
{
private PrintDocument ThePrintDocument;
private Font titleFont;
private Font theFont;
private Color FontColor;
private float CurrentY;
static int PageNumber;
private int PageWidth;
private int PageHeight;
private int LeftMargin;
private int TopMargin;
private int RightMargin;
private int BottomMargin;
private ArrayList textList = new ArrayList();
private int currentIndex = 0;
public MyPrinter(PrintDocument _thePrintDocument, Font _theFont, Font _titleFont,Color _FontColor, ArrayList _textList)
{
ThePrintDocument = _thePrintDocument;
theFont = _theFont;
titleFont = _titleFont;
FontColor = _FontColor;
PageNumber = 0;
textList = _textList;
if (!ThePrintDocument.DefaultPageSettings.Landscape)
{
PageWidth = ThePrintDocument.DefaultPageSettings.PaperSize.Width;
PageHeight = ThePrintDocument.DefaultPageSettings.PaperSize.Height;
}
else
{
PageHeight = ThePrintDocument.DefaultPageSettings.PaperSize.Width;
PageWidth = ThePrintDocument.DefaultPageSettings.PaperSize.Height;
}
LeftMargin = ThePrintDocument.DefaultPageSettings.Margins.Left;
TopMargin = ThePrintDocument.DefaultPageSettings.Margins.Top;
RightMargin = ThePrintDocument.DefaultPageSettings.Margins.Right;
BottomMargin = ThePrintDocument.DefaultPageSettings.Margins.Bottom;
}
public bool DrawDocument(Graphics g)
{
try
{
DrawHeader(g);
bool bContinue = DrawItems(g);
g.Dispose();
return bContinue;
}
catch (Exception ex)
{
MessageBox.Show("失败" + ex.Message.ToString(), " - Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
g.Dispose();
return false;
}
}
public void DrawHeader(Graphics g)
{
CurrentY = (float)TopMargin;
PageNumber++;
string PageString = "第" + PageNumber+"页";
StringFormat PageStringFormat = new StringFormat();
PageStringFormat.Trimming = StringTrimming.Word;
PageStringFormat.FormatFlags = StringFormatFlags.NoWrap | StringFormatFlags.LineLimit | StringFormatFlags.NoClip;
PageStringFormat.Alignment = StringAlignment.Far;
RectangleF PageStringRectangle = new RectangleF((float)LeftMargin, CurrentY, (float)PageWidth - (float)RightMargin - (float)LeftMargin, g.MeasureString(PageString, theFont).Height);
g.DrawString(PageString, theFont, new SolidBrush(Color.Black), PageStringRectangle, PageStringFormat);
CurrentY += g.MeasureString(PageString, theFont).Height;
StringFormat TitleFormat = new StringFormat();
TitleFormat.Trimming = StringTrimming.Word;
TitleFormat.FormatFlags = StringFormatFlags.NoWrap | StringFormatFlags.LineLimit | StringFormatFlags.NoClip;
TitleFormat.Alignment = StringAlignment.Center;
RectangleF TitleRectangle = new RectangleF((float)LeftMargin, CurrentY, (float)PageWidth - (float)RightMargin - (float)LeftMargin, g.MeasureString("收费单", titleFont).Height);
g.DrawString("收费单",titleFont,new SolidBrush(FontColor),TitleRectangle,TitleFormat);
CurrentY +=g.MeasureString("收费单",titleFont).Height;
}
public bool DrawItems(Graphics g)
{
StringFormat TextFormat = new StringFormat();
TextFormat.Trimming = StringTrimming.Word;
TextFormat.FormatFlags = StringFormatFlags.NoWrap | StringFormatFlags.LineLimit | StringFormatFlags.NoClip;
TextFormat.Alignment = StringAlignment.Near;
for (int i = currentIndex; i < textList.Count; i++)
{
string var = textList[i].ToString();
RectangleF TextRectangle = new RectangleF((float)LeftMargin, CurrentY, (float)PageWidth - (float)RightMargin - (float)LeftMargin, g.MeasureString("收费单", titleFont).Height);
g.DrawString(var, theFont, new SolidBrush(FontColor), TextRectangle, TextFormat);
CurrentY = CurrentY + g.MeasureString(var, theFont).Height;
if ((int)CurrentY > (PageHeight - TopMargin - BottomMargin))
{
currentIndex = i+1;
return true;
}
}
return false;
}
}
3，回到原来的Form中，给MyPrintDocument添加PrintPage事件
private void MyPrintDocument_PrintPage(object sender, PrintPageEventArgs e)
{
bool hasNextPage = mp.DrawDocument(e.Graphics);
if (hasNextPage)
{
e.HasMorePages = true;
}
}
4，撰写打印机设置对话框函数
private bool SetupThePrinting()
{
PrintDialog MyPrintDialog = new PrintDialog();
MyPrintDialog.AllowCurrentPage = false;
MyPrintDialog.AllowPrintToFile = false;
MyPrintDialog.AllowSelection = false;
MyPrintDialog.AllowSomePages = false;
MyPrintDialog.PrintToFile = false;
MyPrintDialog.ShowHelp = false;
MyPrintDialog.ShowNetwork = false;
if (MyPrintDialog.ShowDialog() != DialogResult.OK)
return false;
MyPrintDocument.DocumentName = "收费单 ";
MyPrintDocument.PrinterSettings = MyPrintDialog.PrinterSettings;
MyPrintDocument.DefaultPageSettings = MyPrintDialog.PrinterSettings.DefaultPageSettings;
MyPrintDocument.DefaultPageSettings.Margins = new Margins(100, 40, 100, 40);
ArrayList textList = new ArrayList();
mp = new MyPrinter(MyPrintDocument, new Font("Tahoma", 8, FontStyle.Regular, GraphicsUnit.Point), new Font(FontFamily.GenericSerif, 18, FontStyle.Bold, GraphicsUnit.Point), Color.Black, textList);
return true;
}
5，最后加上打印按钮，打印预览按钮的单击事件
1），打印按钮的单击事件
private void btnPrint_Click(object sender, EventArgs e)
{
if (SetupThePrinting())
MyPrintDocument.Print();
}
2）打印预览按钮的单击事件（根据需要）
private void btnPrintPreview_Click(object sender, EventArgs e)
{
if (SetupThePrinting())
{
PrintPreviewDialog MyPrintPreviewDialog = new PrintPreviewDialog();
MyPrintPreviewDialog.Document = MyPrintDocument;
MyPrintPreviewDialog.ShowDialog();
}
}
6，现在你或许要问，那我的打印数据如何加入呢？其实就在刚才写的打印机设置对话框函数里面，如下：
ArrayList textList = new ArrayList();
//textList.Add("收费单");
//textList.Add("2009-04-01");
//textList.Add("开始时间：12:00 ");
//textList.Add("结束时间：13:00 ");
//textList.Add("时间单位：4 ");
//textList.Add("单位时间价格：20.00元 ");
//textList.Add("消费价格：80.00元 ");
//textList.Add("------------------------------------------------------------- ");
//textList.Add("2009-04-01 ");
//textList.Add("开始时间：12:20 ");
//textList.Add("开始时间：12:20 ");
//textList.Add("时间单位：3 ");
//textList.Add("单位时间价格：20.00元 ");
//textList.Add("消费金额：60.00元 ");
//textList.Add("------------------------------------------------------------- ");
//textList.Add("合计：140.00元 ");
//textList.Add("2");
mp = new MyPrinter(MyPrintDocument, new Font("Tahoma", 8, FontStyle.Regular, GraphicsUnit.Point), new Font(FontFamily.GenericSerif, 18, FontStyle.Bold, GraphicsUnit.Point), Color.Black, textList);
return true;
也就是，你只要自己根据你现有的数据将信息一行一行Add到textList中，就可以了
楼上的，1万行你复制一万行？for循环留着干嘛的啊？个人觉得不一定现成的东西都是对自己最有利的。
付参考效果图。
