你能請嘗試更改連接字符串提供商

嘗試 { 串conString =「供應商= Microsoft.Jet.OLEDB.4.0;數據源= C：\ ZIP.DBF;擴展屬性= dBase IV「; OleDbConnection conn = new OleDbConnection（conString）; command = conn。 CreateCommand（）;

 // create the DataSet 
    DataSet ds = new DataSet (); 
    dataGridView1 . DataSource = null; 

    // open the connection 
    conn . Open (); 
    string commandString = "Select * from ZIP.DBF"; 
    // run the query 
    command . CommandText = commandString; 
    OleDbDataAdapter adapter = new OleDbDataAdapter (command); 
    adapter . Fill (ds); 

    // close the connection 
    conn . Close (); 

    // set the grid's data source 
    dataGridView1 . DataSource = ds . Tables [ 0 ]; 
    } 
catch (Exception ex) 
    { 
    MessageBox . Show ( ex . Message); 

    }
