asp.net – System.Data.OleDb.OleDbException：找不到可安装的ISAM

我在网上搜索过,发现很多人都在问这个问题,但没有人能解决我的问题.

我有一个Connection类,以及一个在页面中使用该类的方法.

DataConn.cs

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: Could not find installable ISAM.

有人可以帮忙吗？

解决方法

...Extended Properties=""Excel 8.0;IMEX=1"""

修改你的连接字符串

String.Format(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=pricelist.xlsx;Extended Properties=""Excel 12.0 Xml;HDR=YES""");

参考：
Could not find installable ISAM
