未在ConnectionString中指定OLE DB提供程序。 '提供者= SQLOLEDB

Question

I am creating an application which uses access file from shared network.The application works fine when the access file is placed local.But when I placed it in shared path and trying to connect.It is throwing an exception." An OLE DB Provider was not specified in the ConnectionString. 'Provider=SQLOLEDB Here is my code:

        string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=\\server\\MyFirstProject\\SampleDB2.accdb";
        using (OleDbConnection con = new OleDbConnection(connectionString))
        {
            string command = "INSERT INTO emp_status(emp_id,hours,feeded_on,comments)";
            command += "VALUES(@emp_id,@hours,@feeded_on,@comments)";

Could anyone help me how to resolve this issue and Am I missing something? I am using OLEB as a datasourse and Access 2013 Any Suggestions or explanations would definitely helps me.

Thanks in advance!!

You need to escape the leading double slash as well...

string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=\\\\server\\MyFirstProject\\SampleDB2.accdb";

I haven't got anything to check this on here, but I'm fairly sure this is your answer. Also, watch out for reserved words, Eg "hours" might be one in which case it should be [hours].

Also, you haven't specifically included adding the parameter values in your question. I assume you are doing it but if not then see my coding example here...
