string sql = "select * from book";

SqlCommand mycomm = new SqlCommand(sql,myconn);

SqlDataReader myreader = mycomm.ExecuteReader();

GridView1.DataSource = myreader;

GridView1.DataBind();

SqlConnection myconn = new SqlConnection();

myconn.ConnectionString = "server=.;database=bookshop;uid=sa;pwd=";

myconn.Open();

string sql = "select * from book";

SqlCommand mycomm = new SqlCommand(sql,myconn);

SqlDataAdapter mysda = new SqlDataAdapter(mycomm);

DataSet myds = new DataSet();//老大是System.Data

mysda.Fill(myds, "mydsBook");

GridView1.DataSource = myds.Tables["mydsBook"];

Answer 1

static void(int[]group)
{
int temp;
int pos=0;
for(int i=0;i< group.Length-1;i++)
{
pos=i;
for(intj=i+1;j<group.Length;j++)
{
if(group[j]<group[pos])
{
pos=j;
}
}//第i个数与最小的数group[pos]交换
temp=group[i];
group[i]=group[pos];
group[pos]=temp;
}
}
