Question

string strcon = ConfigurationManager.ConnectionStrings["CompanyInfoSDN"].ConnectionString.ToString();
string str = "select * from WorkInfo";
SqlConnection con = new SqlConnection(strcon);
con.Open();
SqlCommand cmd = new SqlCommand(str, con);
SqlDataAdapter adp = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
adp.Fill(ds, "workinfo");
GridView1.DataSource = ds;
GridView1.DataBind();
GridView1.DataMember = "workinfo";

Answer 1

string strcon = ConfigurationManager.ConnectionStrings["CompanyInfoSDN"].ConnectionString.ToString();//定义连接字符串
string str = "select * from WorkInfo";//定义sql语句
SqlConnection con = new SqlConnection(strcon);//定义连接
con.Open();//建立连接
SqlCommand cmd = new SqlCommand(str, con);//建立command对象
SqlDataAdapter adp = new SqlDataAdapter(cmd);//建立适配器对象
DataSet ds = new DataSet();//建立数据集对象
adp.Fill(ds, "workinfo");//将数据库表workinfo中的数据填充至数据集ds
GridView1.DataSource = ds;GridView1.DataBind();//这两句将数据集ds与gridview1对象绑定
GridView1.DataMember = "workinfo";//将数据库表workinfo中的数据填充至gridview1对象
