问题描述
大家好，
我想将datagridview导出为PDF文件，生成pdf后我无法打开该文件..当我尝试打开它显示文件已损坏的错误消息，也没有得到Pdf生成成功消息。
这是我的代码：
private void btnExportPdf_Click（string heading，string filename）
{
try
{
SaveFileDialog saveFileDialog = new SaveFileDialog（）;
saveFileDialog.Filter =All Files | *。*;
if（saveFileDialog.ShowDialog （）== DialogResult.OK）
{
string path = saveFileDialog.FileName;
文件pdfdoc =新文件（PageSize.A4）; //设置PDF的页面大小
PdfWriter writer = PdfWriter.GetInstance（pdfdoc，new FileStream（path +。pdf，FileMode.Create））; //使用PDF Writer类生成PDF
writer.PageEvent = new PDFFooter（）;
//打开PDF以从文本框中写入数据
PdfPTable table = new PdfPTable（dataGridView1.Columns.Count）;
//table.TotalWidth = GridView 。宽度;
float [] widths = new float []
{
dataGridView1.Columns [0] .Width，dataGridView1.Columns [1] .Width，dataGridView1.Columns [2] .Width
};
table.SetWidths（widths）;
table.HorizontalAlignment = 1; // 0 - 左，1 - 中，2 - 右;
table.SpacingBefore = 2.0F;
PdfPCell cell = null;
pdfdoc.Open（）;
//doc.Open（）;
//短语p =新短语（new Chunk（heading，titleFont））;
// doc.Add（p）;
foreach（DataGridViewColumn c in dataGridView1.Columns）
{
cell = new PdfPCell（new Phrase（new Chunk（c.HeaderText）））;
cell.HorizontalAlignment = PdfPCell.ALIGN_CENTER;
cell.VerticalAlignment = PdfPCell.ALIGN_CENTER;
table.AddCell（cell）;
}
if（ dataGridView1.Rows.Count> 0）
{
for（int i = 0; i< dataGridView1.Rows.Count; i ++）
{
PdfPCell [] objcell = new PdfPCell [dataGridView1.Columns.Count];
for（int j = 0; j< dataGridView1.Columns.Count - 1; j ++）
{
cell = new PdfPCell（new Phrase（dataGridView1.Rows [ i] .Cells [j] .Value.ToString（）））;
cell.HorizontalAlignment = PdfPCell.ALIGN_CENTER;
cell.VerticalAlignment = PdfPCell.ALIGN_CENTER;
table.AddCell（cell）;
//lstCells.Add(cell）;
objcell [j] = cell;
}
PdfPRow newrow = new PdfPRow（objcell）;
table.Rows.Add（newrow）;
}
}
pdfdoc.Add（table）;
MessageBox .Show（Pdf Generation Successfully。）;
pdfdoc.Close（）;
}
}
catch（Exception ex）
{
MessageBox.Show（pdf Generation中的错误。）;
}
}
