C#,ASP.NET中把Excel的数据导入SQLServer
注：注意Excel中的格式，带格式的excel可能导入出错。
陷阱如：如某列值为：“1-1”，在excel中如果不设置为“文本格式”，极有可能会默认为：2017-1-1，注意调整格式。
aspx:
cs中：
protected void Export_Click(object sender, EventArgs e)
{
string fileName = fileId.FileName;
string savePath = Server.MapPath("~/file/");
FileOperatpr(fileName, savePath); //创建文件夹。
fileId.SaveAs(savePath + fileName); //保存（前台的FileUpload控件）
DataOperator(fileName, savePath); //开始传输数据
}
private void DataOperator(string fileName, string savePath)
{
//这里的Microsoft.ACE.OLEDB.12.0还有一种，这是由于EXCEL版本不同而定义的，具体可以搜索下。
string myString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + savePath + fileName + ";Extended Properties=Excel 8.0";
OleDbConnection oconn = new OleDbConnection(myString);
oconn.Open();
DataSet ds = new DataSet();
OleDbDataAdapter oda = new OleDbDataAdapter("select * from [Sheet1$]", oconn);
oda.Fill(ds);
oconn.Close();
DataSetOperator(ds, savePath + fileName); //DataSet的数据，然后封装进去。
}
private void DataSetOperator(DataSet ds, string filePath) //数据正式进行操作，并导入数据库
{
SqlConnection conn = new SqlConnection("Data Source=XXXXX;Database=XXXXXXXX;Uid=sa;Pwd=XXXXXXXXX;"); //数据库连接。
