用sql查詢結果填充列表框

Question

我想構建一個將運行存儲過程的sql查詢。然後我需要此查詢的結果出現在用戶可以從中選擇所需結果的列表框中。

請問有人可以告訴我如何從頭開始構建SQL查詢，然後告訴我如何將這個結果放入一個列表框中？

在此先感謝！

using System.Data; 
using System.Data.SqlClient; 
using System.Windows.Forms; 

namespace WindowsFormsApplication1 
{ 
    public partial class Form1 : Form 
    { 
     public Form1() 
     { 
      InitializeComponent(); 
      FillData(); 
     } 

     void FillData() 
     { 
      var connString = ConfigurationManager 
       .ConnectionStrings[name].ConnectionString; 

      using (SqlConnection c = new SqlConnection(connString)) 
      { 
       c.Open(); 

       // use a SqlAdapter to execute the query 
       using (SqlDataAdapter a = new SqlDataAdapter("SELECT * FROM EmployeeIDs", c)) 
       {    
        // fill a data table 
        var t = new DataTable(); 
        a.Fill(t); 

        // Bind the table to the list box 
        listBox1.DisplayMember = "NameOfColumnToBeDisplayed"; 
        listBox1.ValueMember = "NameOfColumnToUseValueFrom"; 
        listBox1.DataSource = t; 
       } 
      } 
     } 
    }   
}

這裏的總體思路...

ListBox lb = new ListBox(); 
string connectionString = "your connection string here"; 
using (SqlConnection con = new SqlConnection(connectionString)) 
{ 
    con.Open(); 
    string query = "SELECT column FROM myitemstable"; 
    using (SqlCommand cmd = new SqlCommand(query, con)) 
    { 
     using (SqlDataReader reader = cmd.ExecuteReader()) 
     { 
      while (reader.Read()) { 
       lb.Items.Add(new ListItem((string)reader["column"])); 
      } 
     } 
    } 
}
