c＃ - 從ms訪問數據庫隨機生成數據

我想做一個C＃程序，將通過單擊按鈕從我的ms訪問數據庫中選擇一個隨機數據..錯誤說，從我創建的OleDbDataReader Data type mismatch in criteria expression.。c＃ - 從ms訪問數據庫隨機生成數據

這就是我目前實現的目標。將不勝感激。

{ 

     OleDbConnection connection = new OleDbConnection(); 

     connection.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\miguel\Documents\QuotesGenFunny.accdb; 
     Persist Security Info=False;"; 

     connection.Open(); 

     OleDbCommand command = new OleDbCommand(); 

     command.Connection = connection; 
     command.CommandText = "SELECT TOP 1 * FROM Funny ORDER BY Rnd(-10000000*TimeValue(Now())*[Author])"; 

     OleDbDataReader reader = command.ExecuteReader(); 

     while (reader.Read()) 
     { 
      listBox1.Items.Add(reader["Author"].ToString()); 
     } 

     connection.Close(); 
    }
