我已经在网上搜索过,发现很多人都在问这个问题,但没有人确定我的答案。
我有一个连接类和一个在页面中使用该类的方法。
数据连接
public static OleDbConnection ConnectExcel()
{
//Store the connection details as a string
string connstr =
String.Format(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=pricelist.xlsx;Extended Properties=Excel 12.0 Xml;HDR=YES");
//Initialise the connection to the server using the connection string.
OleDbConnection oledbConn = new OleDbConnection(connstr);
//Open the connection, we do this here so we can instantly be able to use SQL commands in the code.
oledbConn.Open();
return oledbConn;
}
public static void DisconnectExcel()
{
_oledbConn.Dispose();
_oledbConn.Close();
}
以及调用它的代码
protected void Page_Load(object sender, EventArgs e)
{
// Connection String
const string xlStr = "SELECT * FROM [Sheet2$]";
// Create OleDbCommand object and select data from worksheet Food
OleDbCommand cmd = new OleDbCommand(xlStr, DataConn.ConnectExcel());
// Create new OleDbDataAdapter
OleDbDataAdapter oleda = new OleDbDataAdapter();
oleda.SelectCommand = cmd;
// Create a DataSet which will hold the data extracted from the worksheet.
DataSet ds = new DataSet();
// Fill the DataSet from the data extracted from the worksheet.
oleda.Fill(ds);
// Bind the data to the GridView
gridPricelist.DataSource = ds;
gridPricelist.DataBind();
}
是的,我仍然得到:
System.Data.OleDb.OleDbException:找不到可安装的 ISAM。
有人可以帮忙吗?
