Answer 1

您使用DataAdapter填充來自SqlServer的數據DataSet。

SqlConnection conn = new SqlConnection(connString); 
SqlCommand cmd = new SqlCommand("SELECT * FROM tbl_tblname", conn); 

try 
{ 

    conn.Open(); 
    DataSet ds = new DataSet(); 
    SqlDataAdapter da = new SqlDataAdapter(); 
    da.SelectCommand = cmd; // Set the select command for the DataAdapter 
    da.Fill(ds); // Fill the DataSet with the DataAdapter 
    DataGridView1.DataSource = ds.Tables[0]; // I just displayed the results in a grid view for simplicity. If Asp.Net you will have to call a DataBind of course. 

catch (Exception ex) 
{ 
    conn.Close(); 
    conn.Dispose(); 
}
