将DataGridView导出到Excel文件
你能说我，我怎么能保存DataGridView内容格式化单元格Backcolor / Forecolor的Exel文件？ 我有这样的DGV：
当我尝试将数据导出到Excel时，我获取了数据，但没有使用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 =“”; //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 + "rn";
// 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 + "rn";
}
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
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像这样：
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：
string.Format("<Cell ss:StyleID="st{0}"><Data ss:Type="String">{1}</Data></Cell>", style, data);
