当我将 gridview 导出到 excel 时,缺少最后一个数据。这是我导出数据的代码。
private void ToCsV(DataGridView dGV, string filename)
{
string stOutput = "";
// Export titles:
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 = 1; 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();
}
这是按钮的代码。
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "Excel Documents (.xls)|*.xls";
sfd.FileName = "";
if (sfd.ShowDialog() == DialogResult.OK)
{
//ToCsV(dataGridView1, @"c:\export.xls");
ToCsV(gvHistory, sfd.FileName); // Here dataGridview1 is your grid view name
}
