C#中使用[GDI+]+PrintDocument实现打印
近日做报表，需要实现一个比较特殊的打印：针对不同患者的药费记录，打印不同的清单，并且支持一次打印多个患者的记录。其效果看起来应该像下面这个样子：
如上所述，使用弱智的水晶报表，就会遇到如何构造数据源的问题，由于不同患者的药费记录和遗嘱记录都不同，而且整体上需要一个患者一个清单，所以其数据源只能为一个数组，而不是简单的
DataTable
。小弟一向对大且笨拙的
CrystalReport
不感冒，再加上对
GDI+
比较痴迷，索性费点功夫，使用
GDI+
来打印上述报表。
首先需要构造数据源，创建一个
ArrayList
对象
a
，然后再把每个患者需要打印的东东保存为一个
ArrayList
放入
ATotal
中。
if
( a !=
null
)
{
a.Clear();
}
for
(
int
m =
0
; m <
3
; m ++ )
{
ArrayList a1 =
new
ArrayList();
string
x0 =
"
住院患者一日清单
"
;
string
x1 =
"
入院日期：
2007-11-11
结算日期：
2007-11-11
至
2007-11-15 "
;
string
x2 =
"
姓名：欧阳峰
住院号：
20090909090
床：

妇科
"
;
string
x3 =
"
项目编号
*
项目名称
*

*
数量
*
单位
"
; //
注意其中的
*
标志
string
[] x4 =
new
string
[
90
]; //
假设有
90
条数据，不固定
for
(
int
i =
0
; i <
90
; i ++ )
{
x4[ i ] =
"juejue1984*www.loyosoft.com*11.00*11*

"
; //
注意其中的
*
标志
}
string
x5 =
"
费用累计：

小计：

;
string
x6 =
"
累计按金：
3600*
余额：
1600 "
;
string
x7 =
"”;
string
x8 =
"”;
a1.Add( x0 );
a1.Add( x1 );
a1.Add( x2 );
a1.Add( x3 );
a1.Add( x4 );
a1.Add( x5 );
a1.Add( x6 );
a1.Add( x7 );
a1.Add( x8 );
a.
Add( a1 );
然后在
PrintDocument
对象的
PrinPage
事件作如下处理：
Size sTotal = new Size( 420, e.PageBounds.Height );
Graphics g = e.Graphics;
Font fTitle = new Font( "
宋体
", 16 ); //
标题字体
int titleHeight = 20; //
标题的高度
int textHeight = 13; //
普通文本的高度
Font fText = new Font( "
宋体
", 9 ); //
文本字体
int top = 30; //
顶部间距
int left = 10; //
左边距
int right = 10; //
右边距
int titleMargin = 15; //
标题和正文行间距
int textMargin = 5; //
行间距
int rectangleMargin = 3; //
边框和文本间距
int oneHeight = 19; //
一行文本
+ 2 *
行间距的高度
int oneWidth = sTotal.Width - left - right; //
打印内容的宽度
int y = 0;
while ( j < a.Count ) // Count
为要打印的患者个数
{
ArrayList a3 = a[ j ] as ArrayList; // a3
位要打印的患者的清单内容。
if( y >= e.PageBounds.Height - titleHeight ) //
如果已经到了底部则开始下一页
{
e.HasMorePages = true;
return;
}
//
string x = a3[ 0 ] as string;
if( !this.JudgeString( x ) ) //
如果此行记录还未打印过
{
//string x = "
住院患者一日清单
"; // a1
SizeF sTitle = g.MeasureString( x, fTitle ); //
计算标题的长度和高度
Point pTitle = new Point( ( sTotal.Width - (int)sTitle.Width ) / 2, y + top ); //
使标题绝对居中
y += top; // 1
//
g.DrawString( x, fTitle, Brushes.Black, pTitle.X, y ); //
标题
this.AddPrintedSign( ref x );
a3[ 0 ] = x; //
标记该患者的此行内容为已经打印过
y += titleHeight + titleMargin; // Y
坐标下移
}
//
if( y >= e.PageBounds.Height - oneHeight )
{
e.HasMorePages = true;
return;
}
////

string r1 = a3[ 1 ] as String;
