Question

c# 怎么创建dao

Answer 1

你的意思是创建ado数据库连接么？
//获得DataSet
string connectionString = "Data Source=192.168.0.x;Initial Catalog=xxxx;User ID=xxxx;Password=xxxxx";
SqlConnection connection = new SqlConnection(connectionString);
SqlCommand command = new SqlCommand("select * from admin", connection);
SqlDataAdapter sqlDA = new SqlDataAdapter();
SqlCommandBuilder build = new SqlCommandBuilder(sqlDA);//构造SQL语句
DataSet dataSet = new DataSet();
sqlDA.SelectCommand = command;
sqlDA.Fill(dataSet);
connection.Close();
