Question

我正在尝试使用C＃在.net中创建程序，用于上传excel文件，读取它并从excel数据中将记录excel文件添加到sql server数据库。这样做时我遇到了错误：无法找到可安装的ISAM？

有人可以帮我解决这个问题吗？

或者可能会提供一些示例代码以不同方式进行此类分配？

protected void Button1_Click(object sender, EventArgs e)
    {
        String excelConnectionString1;
        String fname = FileUpload1.PostedFile.FileName;
        if (FileUpload1.PostedFile.FileName.EndsWith(".xls"))
        {
            String excelsheet;
            FileUpload1.SaveAs(Server.MapPath("~/file/" + FileUpload1.FileName));

            if (FileUpload1.PostedFile.FileName.EndsWith(".xls"))
            {
                excelConnectionString1 = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath("~/file/" + FileUpload1.FileName) + ";Extended Properties=Excel 8.0;HDR=Yes;";
                OleDbConnection myEcelConnection1 = new OleDbConnection(excelConnectionString1);
                myEcelConnection1.Open();
                if (txtsheet.Text.Length == 0)
                {
                    lblmsg.Text = "Please Write File Name";
                }
                else
                {
                    excelsheet = "[" + txtsheet.Text + "$" + "]";
                    string sheet = "Select * from [" + txtsheet.Text + "$" + "]";
                    OleDbCommand cmd1 = new OleDbCommand(sheet, myEcelConnection1);
                    cmd1.CommandType = CommandType.Text;
                    OleDbDataAdapter myAdapter1 = new OleDbDataAdapter(cmd1);
                    DataSet myDataSet1 = new DataSet();
                    myAdapter1.Fill(myDataSet1);
                    int a = myDataSet1.Tables[0].Rows.Count - 1;
                    string name;
                    string dob;
                    for (int i = 0; i <= a; i++)
                    {
                        name = myDataSet1.Tables[0].Rows[i].ItemArray[0].ToString();
                        dob = myDataSet1.Tables[0].Rows[i].ItemArray[1].ToString();
                        SqlConnection con = new SqlConnection("Connection String for Sql Server");
                        con.Open();
                        SqlCommand command = new SqlCommand("Insert into info(name,dob)values(@valname,@valdob)", con);
                        command.Parameters.Add("@valname", SqlDbType.VarChar, 50).Value = name;
                        command.Parameters.Add("@valdob", SqlDbType.VarChar, 50).Value = dob;
                        command.CommandType = CommandType.Text;
                        SqlDataAdapter da = new SqlDataAdapter(command);
                        DataSet ds = new DataSet();
                        da.Fill(ds);
                        con.Close();
                    }
                }
            }
        }
    }
}

}

没有64位版本的Jet OLEDB驱动程序，所以如果你在64位操作系统上运行它，你可能需要在.NET应用程序中定位x86而不是任何CPU。

或

当连接字符串的语法不正确时，也会生成此错误。这在使用多个扩展属性参数时通常会发生。以下是一个例子：

ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=e:\My Documents\Book20.xls;Extended Properties=""Excel 12.0;HDR=NO;IMEX=1"""

像这样更改连接字符串

ConnectionString=" Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\NAVEEN KUMAR\DOTNET\windows\WindowsApplication1\WindowsApplication1\123.xls;Excel 12.0 Xml;HDR=YES"

找不到可安装的ISAM
