网络编程聊天室主要代码
C#.net聊天室制作代码
2012-2-6聊天室制作流程：建立发送页面send.aspx，显示页面showmessage.aspx,主要是这两个，还可以加显示所以用户名字exit.aspx；思路：聊天室要用到数据库，所以在发送页面需要做的是把用户填好的东西加入到数据库储存起来。
到显示页面和显示所以用户页面就顺理成章的把数据库用户填写的信息读取出来这就构成了一个聊天室的主要骨架。
第一个发送页面send.aspx前台代码：<body><form id="form1"runat="server"><div></div><br/><table align="center"width="600"height="150"><tr><td><strong><span style="color: #ff00ff">内容：</span></strong></td><td><asp:TextBox ID="TextBoxContent"Width="302px"Height="50"runat="server"></asp:TextBox> <asp:Button ID="ButtonSpeak"runat="server"Text="发言"Width="72px"></asp:Button><asp:Button ID="ButtonExit"runat="server"Text="离开"Width="64px"Height="23px"></asp:Button><asp:DropDownList ID="DropDownListColor"runat="server"><asp:ListItem Value="black"Selected="True">黑色</asp:ListItem><asp:ListItem Value="red">红色</asp:ListItem><asp:ListItem Value="blue">蓝色</asp:ListItem><asp:ListItem Value="green">绿色</asp:ListItem></asp:DropDownList><asp:DropDownList ID="DropDownListEmotion"runat="server"><asp:ListItem Value="微笑着">微笑着</asp:ListItem><asp:ListItem Value="无奈地">无奈地</asp:ListItem><asp:ListItem Value="哭丧着脸">哭丧着脸</asp:ListItem> </asp:DropDownList></td></tr></table></form></body>后台：send.aspx.csusing System;using System.Data;using System.Configuration;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;using System.Data.SqlClient;public partial class_Default : System.Web.UI.Page{protected void Page_Load(object sender, EventArgs e){}public DBConnection conn = new DBConnection();protected void ButtonSpeak_Click(object sender, EventArgs e){SqlConnection connection = new SqlConnection(ConfigurationSettings.AppSettings["ConnStr"]);connection.Open();string createTime = System.DateTime.Now.ToString();//发言时间string content = TextBoxContent.Text; //发言内容string color = DropDownListColor.SelectedItem.Value; //颜色string emotion = DropDownListEmotion.SelectedItem.Value; //表情string sql;//SqlCommand cmd = new SqlCommand(sql, connection);//SqlDataReader dr = conn.ExecuteReader(sql);sql = "Insert into message(username,createtime,content1,color,emotion) values('"+ Session["username"]+ "','" + createTime+ "','" +content + "','" + color + "','" + emotion + "')";conn.Updata(sql);TextBoxContent.Text="";}protected void ButtonExit_Click(object sender, EventArgs e){Session["username"] = null;Response.Redirect("re.aspx");}}截图：--------------------------------------------------------------------------------------------------------------------------------------------------说明：这里因为要用到数据库sql 所以在开头加上命名空间：using System.Data.SqlClient;还有链接数据库的web.config 文件Web 。
