你能说我,我怎么能用格式化单元格Backcolor / Forecolor将DataGridView的内容保存到Exel文件?我有这样的DGV:
当我尝试将数据导出到Excel时,我得到了数据,但是没有Forecolor,我尝试了几种方法,但它不起作用!事先谢谢!
private void btnExport_Click(object sender,EventArgs e) {
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "Excel Documents (*.xls)|*.xls";
sfd.FileName = "export.xls";
if (sfd.ShowDialog() == DialogResult.OK)
{
//ToCsV(dataGridView1, @"c:\export.xls");
ToCsV1(dataGridView1, sfd.FileName);
}
}
private void ToCsV1(DataGridView dGV,string filename) { string stOutput ="&#34 ;; //导出标题: string sHeaders ="";
for (int j = 0; j < dGV.Columns.Count; j++)
sHeaders = sHeaders.ToString() + Convert.ToString(dGV.Columns[j].HeaderText) + "\t";
stOutput += sHeaders + "\r\n";
// Export data.
for (int i = 0; i < dGV.RowCount - 1; i++)
{
string stLine = "";
for (int j = 0; j < dGV.Rows[i].Cells.Count; j++)
stLine = stLine.ToString() + Convert.ToString(dGV.Rows[i].Cells[j].Value) + "\t";
stOutput += stLine + "\r\n";
}
Encoding utf16 = Encoding.GetEncoding(1254);
byte[] output = utf16.GetBytes(stOutput);
FileStream fs = new FileStream(filename, FileMode.Create);
BinaryWriter bw = new BinaryWriter(fs);
bw.Write(output, 0, output.Length); //write the encoded file
bw.Flush();
bw.Close();
fs.Close();
}

尝试导出到ExcelXML
示例:
using (var writer = new StreamWriter(fileDialog.OpenFile(), Encoding.UTF8))
{
if (format == "XML")
{
writer.WriteLine("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
writer.WriteLine("<?mso-application progid=\"Excel.Sheet\"?>");
writer.WriteLine("<Workbook xmlns=\"urn:schemas-microsoft-com:office:spreadsheet\">");
writer.WriteLine("<DocumentProperties xmlns=\"urn:schemas-microsoft-com:office:office\">");
writer.WriteLine("<Author></Author>");
writer.WriteLine("<Created>" + DateTime.Now.ToLocalTime().ToLongDateString() + "</Created>");
writer.WriteLine("<LastSaved>" + DateTime.Now.ToLocalTime().ToLongDateString() + "</LastSaved>");
writer.WriteLine("<Company></Company>");
writer.WriteLine("<Version>12.00</Version>");
writer.WriteLine("</DocumentProperties>");
if (showGroupHeaders)
AddStyles(writer, groupDesc.Count());
writer.WriteLine(
"<Worksheet ss:Name=\"Silverlight Export\" xmlns:ss=\"urn:schemas-microsoft-com:office:spreadsheet\">");
writer.WriteLine("<Table>");
}
writer.Write(text.ToString());
if (format == "XML")
{
writer.WriteLine("</Table>");
writer.WriteLine("</Worksheet>");
writer.WriteLine("</Workbook>");
}
writer.Close();
}
AddStyle的位置如下:
private static void AddStyles(StreamWriter writer, int groupCount)
{
writer.WriteLine("<Styles>");
for (int i = 0; i < groupCount; i++)
{
int shift = i % _headerColor.Count();
var color = _headerColor[shift];
writer.WriteLine("<Style ss:ID=\"st{0}\">", i + 1);
writer.WriteLine("<Interior ss:Color=\"#{0:X2}{1:X2}{2:X2}\" ss:Pattern=\"Solid\"/>", color.R, color.G, color.B);
writer.WriteLine("</Style>");
}
writer.WriteLine("</Styles>");
}
并设置单元格背景颜色:
string.Format("<Cell ss:StyleID=\"st{0}\"><Data ss:Type=\"String\">{1}</Data></Cell>", style, data);
