在C＃控制台应用程序中访问数据库

Question

The current problem I'm having is an error message that it could not find file C: now I dont know what the problem is because the file is in that location. I have I tried in both .accbd and .mbd.

private static OleDbConnection GetConnection()    
{
    OleDbConnection conn = new OleDbConnection();
    String connectionString = 
            @"Provider=Microsoft.JET.OlEDB.4.0;"
            + @"Data Source= C:\Temp\F1\Docs\Expeditors Project\Table1.accbd";

    conn = new OleDbConnection(connectionString);
    conn.Open();
    return conn;
}

Answer 1

Do you tried another Provider? For example:

Provider=Microsoft.ACE.OLEDB.12.0;
Data Source=C:\Temp\F1\Docs\Expeditors Project\Table1.accbd;

Answer 2

try \\\\ in Data Source Path

like below -

OleDbConnection con = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\\Data\test.mdb;Persist Security Info=False");

Answer 3

try this `

    `private static OleDbConnection GetConnection() throws SQLException{
        { 
    if (conn==null) 
{ 
            try{                                                                                    OleDbConnection conn = new OleDbConnection();
            String connectionString = @"Provider=Microsoft.JET.OlEDB.4.0;"
                                      + @"Data Source= C:\Temp\F1\Docs\Expeditors Project\Table1.accbd";
            conn = new OleDbConnection(connectionString);
            conn.Open();

            return conn;
        }}
    catch(Exception e){
    e.printStackTrace();
    }
