[解决办法]
string connectionString= " ";//填你的连接字符串
string queryString =
"SELECT OrderID, CustomerID FROM dbo.Orders; ";
using (SqlConnection connection =
new SqlConnection(connectionString))
{
SqlCommand command =
new SqlCommand(queryString, connection);
connection.Open();
SqlDataReader reader = command.ExecuteReader();
// Call Read before accessing data.
while (reader.Read())
{
Console.WriteLine(String.Format( "{0}, {1} ",
reader[0], reader[1]));
}
// Call Close when done reading.
reader.Close();
}
