using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Data.OleDb;
using System.IO;
namespace WindowsFormsApplication3
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
public DataSet ReadExcel(string path)
{
string strConn =
"Provider=Microsoft.Jet.OLEDB.4.0;"
+ "Data Source=" + @path + ";"
+ "Extended Properties=Excel 8.0;";
OleDbConnection conn = new OleDbConnection(strConn);
conn.Open();
string strExcel = "";
OleDbDataAdapter myCommand = null;
DataSet ds = null;
strExcel = "select 班级,学号,姓名,类别,作业网址 from [sheet1$]";
myCommand = new OleDbDataAdapter(strExcel, strConn);
DataTable table1 = new DataTable();
ds = new DataSet();
myCommand.Fill(table1);
myCommand.Fill(ds);
dataGridView1.DataSource = table1;
return ds;
}
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog openfile = new OpenFileDialog();
openfile.Filter = "工作薄(*.xls)|*.xls|所有文件(*.*)|*.*|工作薄(*.xlsx)|*.xlsx";
if (openfile.FilterIndex == 1 && openfile.ShowDialog() == DialogResult.OK)
{
DataSet dataSet = ReadExcel(openfile.FileName);
String name = "";
using (StreamWriter sw = new StreamWriter(@"C:\Users\Administrator.LBDZ-20121019BZ\Documents\学习\C#\3\excel.txt", false, Encoding.Default))
{
foreach (DataTable table in dataSet.Tables)
{
foreach (DataRow row in table.Rows)
{
foreach (DataColumn column in table.Columns)
{
//Console.WriteLine(row[column]);
if (column.ColumnName == "姓名")
{
name = row[column].ToString();
}
if (column.ColumnName == "作业网址")
{
sw.WriteLine(name + ":" + row[column].ToString() + ";");
}
}
}
}
}
using (StreamWriter sw = new StreamWriter(@"C:\Users\Administrator.LBDZ-20121019BZ\Documents\学习\C#\3\excel.html", false, Encoding.Default))
{
sw.WriteLine("<html>");
sw.WriteLine("<body>");
sw.WriteLine("<table cellPadding=1 align=center>");
foreach (DataTable table in dataSet.Tables)
{
foreach (DataRow row in table.Rows)
{
foreach (DataColumn column in table.Columns)
{
//Console.WriteLine(row[column]);
if (column.ColumnName == "姓名")
{
// sw.Write("<a href=\"" + row[column] + "\">");
name = row[column].ToString();
sw.WriteLine("<tr>" + "<td>" + name + "</td>");
}
if (column.ColumnName == "作业网址")
{
sw.WriteLine("<td>"
+ "<A Href=\"" + row[column].ToString()
+ "\">"
+ row[column].ToString()
+ "</a>");
sw.WriteLine("</td>");
sw.WriteLine("</tr>");
}
}
}
}
sw.WriteLine("</table>");
sw.WriteLine("</body>");
sw.WriteLine("</html>");
