Connection Property Has Not Been Initialized Error

I am baffled as to why this is being thrown as I feel like that is what the line I set the connection in and the line I open the connection do....

string filePath = "C:\\Database\\Masterdatabase\\DB1.mdb";
System.Data.OleDb.OleDbConnection oledbconn = new System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.
OLEDB.4.0;Data Source=" + filePath);
Oledbconn.Open();
OleDbCommand olecomm = new OleDbCommand("Select * from tbl_information, oledbconn");
System.Data.OleDb.OleDbDataReader dr = null;
//It hits here and error thrown
try { dr = olecomm.ExecuteReader(); }
catch (Exception ex) { MessageBox.Show(ex.ToString()); };
