winfrom导入excel内容,要求能够excel中多个工作簿的内容。代码如下:
#region 导入excel数据
private void button2_Click(
object sender, EventArgs e)
{
OpenFileDialog openFileDialog =
new OpenFileDialog();
openFileDialog.Filter =
"表格文件 (*.xls)|*.xls";
openFileDialog.RestoreDirectory =
true;
openFileDialog.FilterIndex =
1;
if (openFileDialog.ShowDialog() ==
DialogResult.OK)
{
Import(openFileDialog.FileName);
}
}
/// <summary>
/// 导入excel数据
/// </summary>
/// <param name="filePath"></param>
/// <returns></returns>
public static bool Import(
string filePath)
{
try
{
//Excel就好比一个数据源一般使用
//这里可以根据判断excel文件是03的还是07的,然后写相应的连接字符串
string strConn =
"Provider=Microsoft.Jet.OLEDB.4.0;" +
"Data Source=" + filePath +
";" +
"Extended Properties=Excel 8.0;";
OleDbConnection con =
new OleDbConnection(strConn);
con.Open();
string[] names =
GetExcelSheetNames(con);
if (names.Length >
0)
{
foreach (
string name
in names)
{
OleDbCommand cmd =
con.CreateCommand();
cmd.CommandText =
string.Format(
" select * from [{0}]", name);
//[sheetName]要如此格式
OleDbDataReader odr =
cmd.ExecuteReader();
while (odr.Read())
{
if (odr[
0].ToString() ==
"序号")
//过滤列头 按你的实际Excel文件
continue;
//数据库添加操作
/*进行非法值的判断
* 添加数据到数据表中
* 添加数据时引用事物机制,避免部分数据提交
* Add(odr[1].ToString(), odr[2].ToString(), odr[3].ToString());//数据库添加操作,Add方法自己写的
* */
}
odr.Close();
}
}
return true;
}
catch (Exception)
{
return false;
}
}
