c#-4.0 - 数着没有。Access Db 中的填充行数

Question

我正在使用以下代码来获取号码。MS Access Db 中的填充行数。但是我在打开命令时收到以下错误

public static int CountRecordsInAccess(string ResultFile)//TODO
        {
            string ResultFilePath = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location) + ResultFile;
            string ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0" + ";Data Source=" + ResultFilePath + ";Extended Properties=Excel 12.0;Persist Security Info=False";
            //Create Connection 
            OleDbConnection AccessConnection = new OleDbConnection(ConnectionString);
            AccessConnection.Open();
            //Create OleDbCommand to fetch data
            OleDbCommand cmd = new OleDbCommand("SELECT COUNT (*) FROM Table1" , AccessConnection);

            int rows = (int)cmd.ExecuteScalar();
            AccessConnection.Close();
            return rows;
        }

请建议我哪里出错了
