I want to read the data from a xl sheet i wrote the code for that but showing error while executing
the error is following

{"The Microsoft Access database engine cannot open or write to the file 'D:\\Gopi.Ch\\DotNetTasks\\XL Sheet\\XL Sheet\\Files'. It is already opened exclusively by another user, or you need permission to view and write its data."}

my code following

string connString = ConfigurationManager.ConnectionStrings["xls"].ConnectionString;
            // Create the connection object
            OleDbConnection oledbConn = new OleDbConnection(connString);
                string path = @"D:\Gopi.Ch\DotNetTasks\XL Sheet\XL Sheet\File\gopi.xlsx";
                OleDbConnection con_excel = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 8.0");
                OleDbDataAdapter adpt = new OleDbDataAdapter("SELECT Country,State,City,Pincode FROM [Sheet1$]", con_excel);
                DataSet ds = new DataSet();
                adpt.Fill(ds, "tbl_temp");
                DataTable dt = new DataTable();
                dt = ds.Tables["FooTable"];
               /* List<SetData> setData = new List<SetData>();
                foreach (DataRow dr in dt.Rows)

                } */

                gdXlData.DataSource = ds.Tables["tbl_temp"];
                // Close connection

What Mistake i did and already installed microsoft oledb 12.0

thanks and regards

@"D:\Gopi.Ch\DotNetTasks\XL Sheet\XL Sheet\Files";
where your file name?

You are missing file name in path variable. Append excel sheet file name with "D:\Gopi.Ch\DotNetTasks\XL Sheet\XL Sheet\Files".

I could't see any mistake in your code, but OleDb locks it for 3 minutes or so.
If you are dealing with xlsx file, I would recommend to use EPPlus: Its simple, clean and will not lock your file like OleDb does.

Wrong connection string, here: Extended Properties=Excel 8.0

1 solution

2 possible reasons:
1) Check path to the file! Are you sure you used XL Sheet twice?
2) Connection string is wrong (see my comment to the question)
Excel connection strings -[^]
Proper connection string should look like:
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\ProperPathToExcelFile.xlsx;Extended Properties="Excel 12.0;HDR=YES";
