            FileStream fs = new FileStream("Loan Calculator.pdf", FileMode.Create, FileAccess.Write, FileShare.None); 
            Document doc = new Document(PageSize.A4); 
            PdfWriter writer = PdfWriter.GetInstance(doc, fs); 
            doc.Open(); 
            doc.Add(new Paragraph("Hello World")); 
            doc.Close(); 
        } 
    } 
}

推荐答案

请看下面的代码

Please have a look at below code

listView1.View = View.Details;
listView1.GridLines = true;
listView1.FullRowSelect = false;

//Add column header
listView1.Columns.Add("ProductName", 100);
listView1.Columns.Add("Price", 70);
listView1.Columns.Add("Quantity", 70);

//Add items in the listview
string[] arr = new string[4];
ListViewItem itm;

//Add first item
arr[0] = "product_1";
arr[1] = "100";
arr[2] = "10";
itm = new ListViewItem(arr);
listView1.Items.Add(itm);

//Add second item
arr[0] = "product_2";
arr[1] = "200";
arr[2] = "20";
itm = new ListViewItem(arr);
listView1.Items.Add(itm);



//Creating iTextSharp Table from the DataTable data
PdfPTable pdfTable = new PdfPTable(listView1.Columns.Count);
pdfTable.DefaultCell.Padding = 3;
pdfTable.WidthPercentage = 30;
pdfTable.HorizontalAlignment = Element.ALIGN_LEFT;
pdfTable.DefaultCell.BorderWidth = 1;

//Adding Header row
foreach (ColumnHeader column in listView1.Columns)
{
    PdfPCell cell = new PdfPCell(new Phrase(column.Text));
    pdfTable.AddCell(cell);
}

//Adding DataRow
foreach (ListViewItem itemRow in listView1.Items)
{
    int i = 0;
    for (i = 0; i < itemRow.SubItems.Count - 1; i++)
    {
        pdfTable.AddCell(itemRow.SubItems[i].Text);
    }
}

//Exporting to PDF
string folderPath = @"D:/Temp/";
if (!Directory.Exists(folderPath))
{
    Directory.CreateDirectory(folderPath);
}
using (FileStream stream = new FileStream(folderPath + "DataGridViewExport.pdf", FileMode.Create))
{
    Document pdfDoc = new Document(PageSize.A2, 10f, 10f, 10f, 0f);
    PdfWriter.GetInstance(pdfDoc, stream);
    pdfDoc.Open();
    pdfDoc.Add(pdfTable);
    pdfDoc.Close();
    stream.Close();
}
