In my DataAccess class I have a private method called GetConnectionString to generate the connection string based on property values. I'm trying to use it to connect to an Access database. In this method is a switch which is evaluated based on the InvariantName. For the OleDb option I have:

DbConnectionStringBuilder csb = _Factory.CreateConnectionStringBuilder();

.
.
.

case "System.Data.OleDb":
    if (_Provider != "")
    {
        csb.Add("Provider", _Provider);
    }
    if (_DataSource != "")
    {
        csb.Add("Data Source", _DataSource);
    }
    if (_InitialCatalog != "")
    {
        csb.Add("Initial Catalog", _InitialCatalog);
    }
    if (_TrustedConnection)
    {
        csb.Add("Integrated Security", "SSPI");
    }
    else
    {
        if (_UserName != "")
        {
            csb.Add("User Id", _UserName);
        }

        if (_Password != "")
        {
            csb.Add("pwd", _Password);
        }
    }

    break;

Then outside the switch I have:

return csb.ConnectionString;

When I step to this line and hover over 'csb', I see

Provider=Microsoft.Jet.OLEDB.4.0;Data Source="M:\APEX Master Database.mdb";Integrated Security=SSPI

When I hover over 'ConnectionString' I see:

Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\"M:\\APEX Master Database.mdb\";Integrated Security=SSPI

Notice the extra slashes before and after the database name.
