1.直接将DataGridView显示的内容导出Excel
public void DataToExcel(DataGridView m_DataView) { SaveFileDialog kk = new SaveFileDialog(); kk.Title = "保存EXECL文件"; kk.Filter = "EXECL文件(*.xls) |*.xls |所有文件(*.*) |*.*"; kk.FilterIndex = 1; if (kk.ShowDialog() == DialogResult.OK) { string FileName = kk.FileName + ".xls"; if (File.Exists(FileName)) File.Delete(FileName); FileStream objFileStream; StreamWriter objStreamWriter; string strLine = ""; objFileStream = new FileStream(FileName, FileMode.OpenOrCreate, FileAccess.Write); objStreamWriter = new StreamWriter(objFileStream, System.Text.Encoding.Unicode); for (int i = 0; i < m_DataView.Columns.Count; i++) { if (m_DataView.Columns[i].Visible == true) { strLine = strLine + m_DataView.Columns[i].HeaderText.ToString() + Convert.ToChar(9); } } objStreamWriter.WriteLine(strLine); strLine = ""; for (int i = 0; i < m_DataView.Rows.Count; i++) { if (m_DataView.Columns[0].Visible == true) { if (m_DataView.Rows[i].Cells[0].Value == null) strLine = strLine + " " + Convert.ToChar(9); else strLine = strLine + m_DataView.Rows[i].Cells[0].Value.ToString() + Convert.ToChar(9); } for (int j = 1; j < m_DataView.Columns.Count; j++) { if (m_DataView.Columns[j].Visible == true) { if (m_DataView.Rows[i].Cells[j].Value == null) strLine = strLine + " " + Convert.ToChar(9); else { string rowstr = ""; rowstr = m_DataView.Rows[i].Cells[j].Value.ToString(); if (rowstr.IndexOf("\r\n") > 0) rowstr = rowstr.Replace("\r\n", " "); if (rowstr.IndexOf("\t") > 0) rowstr = rowstr.Replace("\t", " "); strLine = strLine + rowstr + Convert.ToChar(9); } } } objStreamWriter.WriteLine(strLine); strLine = ""; } objStreamWriter.Close(); objFileStream.Close(); MessageBox.Show(this, "保存EXCEL成功", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information); } }
用DataGridView绑定的DataTable为参数,导出Excel
1public void DataToExcel(DataTable m_DataTable)
2 {
3 SaveFileDialog kk = new SaveFileDialog();
4 kk.Title = "保存EXECL文件";
5 kk.Filter = "EXECL文件(*.xls) |*.xls |所有文件(*.*) |*.*";
6 kk.FilterIndex = 1;
7 if (kk.ShowDialog() == DialogResult.OK)
8 {
9 string FileName = kk.FileName + ".xls";
10 if (File.Exists(FileName))
11 File.Delete(FileName);
12 FileStream objFileStream;
13 StreamWriter objStreamWriter;
14 string strLine = "";
15 objFileStream = new FileStream(FileName, FileMode.OpenOrCreate, FileAccess.Write);
16 objStreamWriter = new StreamWriter(objFileStream, System.Text.Encoding.Unicode);
17 for (int i = 0; i < m_DataTable.Columns.Count; i++)
18 {
19 strLine = strLine + m_DataTable.Columns[i].Caption.ToString() + Convert.ToChar(9);
20 }
21 objStreamWriter.WriteLine(strLine);
22 strLine = "";
23
24 for (int i = 0; i < m_DataTable.Rows.Count; i++)
25 {
26 for (int j = 0; j < m_DataTable.Columns.Count; j++)
27 {
28 if (m_DataTable.Rows[i].ItemArray[j] == null)
29 strLine = strLine + " " + Convert.ToChar(9);
30 else
31 {
32 string rowstr = "";
33 rowstr = m_DataTable.Rows[i].ItemArray[j].ToString();
34 if (rowstr.IndexOf("\r\n") > 0)
35 rowstr = rowstr.Replace("\r\n", " ");
36 if (rowstr.IndexOf("\t") > 0)
37 rowstr = rowstr.Replace("\t", " ");
38 strLine = strLine + rowstr + Convert.ToChar(9);
39 }
40 }
41 objStreamWriter.WriteLine(strLine);
42 strLine = "";
43 }
44 objStreamWriter.Close();
45 objFileStream.Close();
46 MessageBox.Show(this, "保存EXCEL成功", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
47 }
48 }
