如何使用itextsharp使用sql server数据从c＃windows窗体创建/导出PDF报告 [英] how to create /export PDF report from c# windows forms with sql server data using itextsharp
问题描述
我的名字在过去的10天里是令人头疼的，我突然想到如何使用itextsharp从c＃windows表单和sql server数据创建PDF报告。
我在sql server 2008中有两个表。
表名：技术员
列名DataType AllowNulls
technician_id（主键）Int No
technician_dob date是
technician_sex nvarchar（10）是
row_upd_date datetime是
user_id Int是
表名：Techniciandetail
列名DataType AllowNulls
Technician_first_name为nvarchar（50）是
Technician_middle_name为nvarchar（50）是
Technician_last_name为nvarchar（50）是
ロw_upd_date datetime是
状态位是
agn（主键）Int No
technician_id Int Yes
user_id Int是
technician_type Int是
下面给出的是使用itextsharp的sql server 2008的c＃代码：
hi my name is vishal for past 10 days i was breaking my head on how to create PDF report from c# windows forms with sql server data using itextsharp.

Technician_last_name nvarchar(50) Yes
row_upd_date datetime Yes
status bit Yes
agn(primary key) Int No
technician_id Int Yes
user_id Int Yes
technician_type Int Yes
Given below is my c# code with sql server 2008 using itextsharp:

{
public partial class frmPDFTechnician : Form

public frmExcelTechnician()
{
InitializeComponent();
}
public DataTable GetDataTable()
{
DataTable table = new DataTable("Techniciandetail" + "Technician");
DataColumn datacolumn_ID = new DataColumn("ID", typeof(Int32));
table.Columns.Add(datacolumn_ID);
DataColumn dataFname = new DataColumn("First Name", typeof(string));
table.Columns.Add(dataFname);

table.Columns.Add(dataMname);
DataColumn dataLname = new DataColumn("Last Name", typeof(string));
table.Columns.Add(dataLname);

table.Columns.Add(DOB);
DataColumn Sex = new DataColumn("Gender", typeof(string));
table.Columns.Add(Sex);

table.Columns.Add(Type);
DataRow drow = table.NewRow();

string query = "Select t.technician_id,td.Technician_first_name,td.Technician_middle_name,td.Technician_last_name,t.technician_dob,t.technician_sex,td.technician_type from Techniciandetail td,Technician t where td.technician_id=t.technician_id and td.status=1";
SqlCommand cmd = new SqlCommand(query, conn);
conn.Open();
SqlDataReader rdr = cmd.ExecuteReader();
while (rdr.Read())
{
drow["ID"] = rdr[0].ToString();
drow["First Name"] = rdr[1].ToString();
drow["Middle Name"] =rdr[2].ToString();
drow["Last Name"] = rdr[3].ToString();
drow["DOB"] = rdr[4].ToString();
drow["Gender"] = rdr[5].ToString();
drow["Designation"] = rdr[6].ToString();
}
table.AcceptChanges();
return table;
}
private void btnExport_Click(object sender, EventArgs e)
{
Document doc = new Document(PageSize.A4.Rotate());
PdfWriter.GetInstance(doc, new FileStream("Technician22.pdf", FileMode.Create));
doc.Open();
Font font10 = FontFactory.GetFont("Arial", 10, BaseColor.BLACK);
Paragraph para = new Paragraph("Technician Details in PDF Document");
DataTable dt = GetDataTable();
PdfPTable table = new PdfPTable(dt.Columns.Count);
PdfPCell cell = null;
cell = new PdfPCell(new Phrase(new Chunk("ID", font10)));
table.AddCell(cell);

table.AddCell(cell);

}
table.SpacingBefore = 15f;
doc.Add(para);
doc.Add(table);
doc.Close();
}
下面给出的是我的sql select查询：
选择t.technician_id，td.Technician_first_name，td .Technician_middle_name，td.Technician_last_name，t.technician_dob，t.technician_sex，td.technician_type from Techniciandetail td，Technician t where td.technician_id = t.technician_id and td.status = 1;
上面的查询在某种程度上执行，因为我在PDF报告的表格中获得了列名。但问题是我只获得了列名，而在下面它没有被sql数据填充。我知道在我的编码中公共DataTable GetDataTable（）函数有一些错误，但我不知道如何修复它？
我想要的是当用户点击btnExport时我需要来自技术人员table-technician_id，technician_dob，technician_sex的数据/值以及来自Techniciandetail table-Technician_first_name，Technician_middle_name，Technician_last_name和technician_type 的值在PDF报告中出现或嵌入或绑定到适当的列。
任何人都可以帮助我！我试过网但没有成功。任何有关解决此问题的帮助或指导都将非常感激。
Given below is my sql select query:
"Select t.technician_id,td.Technician_first_name,td.Technician_middle_name,td.Technician_last_name,t.technician_dob,t.technician_sex,td.technician_type from Techniciandetail td,Technician t where td.technician_id=t.technician_id and td.status=1";
The above query executes to some extent as i get column names in table in PDF report. But the problem is that i get column names only and below it is not being filled by sql data. I know there is some mistake in public DataTable GetDataTable() function in my coding but i dont know how to fix it?
What i want is when user click btnExport i want datas/values from Technician table-technician_id,technician_dob,technician_sex and values from Techniciandetail table-Technician_first_name,Technician_middle_name,Technician_last_name and technician_type to be present or embedded or binded into appropriate columns in PDF Report.
Can anyone help me please! I have tried through net but with no success. Any help or guidance in solving this problem would be greatly appreciated.
