用iTextSharp制作pdf

这段时间在作一个澳洲项目，其中有用到iTextSharp生成pdf，以下是部分代码：

首先制作通用表格
1、表格样式

private void AddTableHeader(Table tPay,string[,] PayBody)
        {
            int lengthV2=PayBody.GetLength(1);
            Phrase phrase=null;
            Cell cell=null;
            for(int i=0;i<lengthV2;i++)
            {
                phrase=new Phrase(PayBody[0,i],FontFactory.GetFont(FontFactory.HELVETICA, 11, Font.NORMAL));
                phrase.Leading=8;
                cell=new Cell();
                cell.Add(phrase);
                if(i==0)
                    cell.HorizontalAlignment=Element.ALIGN_LEFT;
                else if(i==lengthV2-1)
                    cell.HorizontalAlignment=Element.ALIGN_RIGHT;
                tPay.AddCell(cell);
            }
        }

2、表格的头

private void AddTableHeader(Table tPay,string[,] PayBody)
        {
            int lengthV2=PayBody.GetLength(1);
            Phrase phrase=null;
            Cell cell=null;
            for(int i=0;i<lengthV2;i++)
            {
                phrase=new Phrase(PayBody[0,i],FontFactory.GetFont(FontFactory.HELVETICA, 11, Font.NORMAL));
                phrase.Leading=8;
                cell=new Cell();
                cell.Add(phrase);
                if(i==0)
                    cell.HorizontalAlignment=Element.ALIGN_LEFT;
                else if(i==lengthV2-1)
                    cell.HorizontalAlignment=Element.ALIGN_RIGHT;
                tPay.AddCell(cell);
            }
        }

3、表格的脚

private void AddTableFooter(Table tPay,string[,] PayBody)
        {

            int lengthV1=PayBody.GetLength(0);
            int lengthV2=PayBody.GetLength(1);
            Phrase phrase=null;
            Cell cell=null;
            for(int i=0;i<lengthV2;i++)
            {
                phrase=new Phrase(PayBody[lengthV1-1,i],FontFactory.GetFont(FontFactory.HELVETICA, 10, Font.NORMAL));
                phrase.Leading=8;
                cell=new Cell();
                cell.Add(phrase);
                cell.Border=Rectangle.TOP_BORDER | Rectangle.BOTTOM_BORDER;
                cell.BorderWidth=1;
                if(i==0)
                    cell.HorizontalAlignment=Element.ALIGN_LEFT;
                else if(i==lengthV2-1)
                    cell.HorizontalAlignment=Element.ALIGN_RIGHT;
                tPay.AddCell(cell);
            }
        }

4、表格的行身

private void AddTableBody(Table tPay,string[,] PayBody)
        {
            int lengthV1=PayBody.GetLength(0);
            int lengthV2=PayBody.GetLength(1);
            Phrase phrase=null;
            Cell cell=null;
            for(int i=1;i<lengthV1-1;i++)
            {
                for(int j=0;j<lengthV2;j++)
                {
                    cell=new Cell();
                    phrase=new Phrase(PayBody[i,j],FontFactory.GetFont(FontFactory.HELVETICA, 10, Font.NORMAL));
                    phrase.Leading=8;
                    cell.Add(phrase);
                    if(j==0)
                        cell.HorizontalAlignment=Element.ALIGN_LEFT;
                    else if(j==lengthV2-1)
                        cell.HorizontalAlignment=Element.ALIGN_RIGHT;
                
                    tPay.AddCell(cell);
                }
            }
        }

至此，于一段落
下面提供一个数组，以传入的DataTable实现以上代码中形参PayBody的传入值，实为表格的数组化体现

//tGSTBody Array
        private string[,] GSTBody
        {
            get
            {
                int len=dt.Rows.Count+2;
                string[,] body=new string[len,6];
                body[0,0]="Date";
                body[0,1]="Request ID";
                body[0,2]="Last name";
                body[0,3]="Product Type";
                body[0,4]="Qty";
                body[0,5]="Rate($)";
                for(int i=0;i<this.dt.Rows.Count;i++)
                {
                    for(int j=0;j<6;j++)
                    {
                        body[i+1,j]=dt.Rows[i][j].ToString();
                        if(j==5)
                            body[i+1,j]="$"+body[i+1,j];
                    }
                }
                body[len-1,0]="Total(ex GST)";
                body[len-1,1]=body[len-1,2]=body[len-1,3]=body[len-1,4]="";
                body[len-1,5]="$"+this.totalEx;
                return body;
            }
        }

最后，你只需要在需要调用的地方编写如下代码即可实现pdf生成多个表格，你可以设计多个数组，即可实现多个表格

Table tGST=new Table(6);
            SetTableStyle(tGST,new int[]{5,3,5,5,2,3},100f);
            AddTableHeader(tGST,GSTBody);
            AddTableBody(tGST,GSTBody);
            AddTableFooter(tGST,GSTBody);
            AddTableExtraFooter(tGST);
            tGST.Offset=30f;


            //add body
            document.Add(tPay);
            document.Add(para);
            document.Add(tSum);
            document.Add(tGST);
