Question

“System.Data.SqlClient.SqlConnection”并不包含“open”的定义

相关的程序代买如下：
string strcnn = "Data Source=localhost; Initial Catalog=BookStore; User ID=osierswallow; Pwd=alizee; Connection TimeOut=30";
SqlConnection SqlCnn = new SqlConnection();
SqlCnn.ConnectionString = strcnn;
SqlCnn.open();
SqlCommand SqlCmd = SqlCnn.CreateCommand();
SqlCmd.CommandText = "select * from T_Publishers; select * from T_BookClass";
SqlDataReader SqlReader = SqlCmd.ExecuteReader();
int ncol = SqlReader.FieldCount;
谢谢！！

Answer 1

应该是 SqlCnn.Open();
不是 SqlCnn.open();
