C#简单文章管理系统后台源码
C#简单文章管理系统后台源码
看到网上各种各样功能强大的cms，相当羡慕啊，工作后一直用的.net开发程序，很想找个时间写个简单的玩玩，正好前些天看到一系统的界面还可以，暂时拿来用下，仅供学习交流使用。
网上的cms功能太强大，我写的代码只是简单的实现了cms中的文章管理功能部分
开发环境 vs2008 SQLEXPRESS2005
1.后台登陆页面
图一
if (Session["ValidateCode"].ToString() == this.tbValidateCode.Text.ToUpper())
{
if (AdminManager.Exist("UserName='" + CommonFunctions.AntiSqlIn(this.tbUserName.Text) + "' and Password='" + CommonFunctions.AntiSqlIn(this.tbPassword.Text) + "'"))
{
Admin admin= AdminManager.GetList(0, "UserName='" + this.tbUserName.Text + "' and Password='" + this.tbPassword.Text + "'", "")[0];
LoginLog loginLog = new LoginLog();
loginLog.AddTime = System.DateTime.Now;
loginLog.Status = 0;
loginLog.IP = Request.UserHostAddress;
loginLog.UserID = admin.ID;
loginLog.Type = 5;
LoginLogManager.AddLoginLog(loginLog);
Session["AdminUser"] = admin;
Response.Redirect("Index.htm");
}
else
{
CommonFunctions.ShowMessage(Page, "账号或密码错误", "");
}
}
else
{
CommonFunctions.ShowMessage(Page, "验证码错误", "");
}
2.登陆后的系统界面
图二
文章列表主要代码
public void BindData()
{
PagedDataSource pds = new PagedDataSource();
string sql = "1=1 ";
if (txtKeyword.Text.Trim() != "")
{
sql += " and title like '%" + CommonFunctions.AntiSqlIn(txtKeyword.Text.Trim()) + "%'";
}
IList<Article> list = ArticleManager.GetList(0, sql + "and CategoryID=6 and Status=0", "id desc");
pds.DataSource = list;
pds.AllowPaging = true;
pds.PageSize = this.AspNetPager1.PageSize;
pds.CurrentPageIndex = this.AspNetPager1.CurrentPageIndex - 1;
repList.DataSource = pds;
repList.DataBind();
this.AspNetPager1.RecordCount = list.Count;
}
分页用的AspNetPager1 控件
主要代码
protected void AspNetPager1_PageChanging(object src, Wuqi.Webdiyer.PageChangingEventArgs e)
{
this.AspNetPager1.CurrentPageIndex = e.NewPageIndex;
BindData();
}
3.添加文章页面
图三
model = new Article();
model.Content = Microsoft.Security.Application.AntiXss.GetSafeHtmlFragment(this.tbContent.Text);
model.Title = Microsoft.Security.Application.AntiXss.GetSafeHtmlFragment(this.tbTitle.Text);
model.CategoryID = Convert.ToInt32(this.ddlCategory.SelectedValue);
model.AddTime = System.DateTime.Now;
model.Status = 0;
try
{
ArticleManager.AddArticle(model);
CommonFunctions.ShowMessage(Page, "添加成功", "ArticleList.aspx");
}
catch (Exception ex)
{
CommonFunctions.ShowMessage(Page, ex.ToString(), "");
}
4.文章管理页面
图4
删除文章代码
protected void gvList_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
Article article = ArticleManager.GetArticleById(Convert.ToInt32(gvList.DataKeys[e.RowIndex].Value));
article.Status = 1;
ArticleManager.ModifyArticle(article);
BindData();
}
光棒效果，文章编号代码
protected void gvList_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowIndex != -1)
{
int id = (e.Row.RowIndex + 1) + gvList.PageSize * gvList.PageIndex;
e.Row.Cells[0].Text = id.ToString();
}
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes.Add("onmouseover", "currentcolor=this.style.backgroundColor;this.style.backgroundColor='#e9f4fd'");
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor=currentcolor");
}
}
分页代码
protected void gvList_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gvList.PageIndex = e.NewPageIndex;
BindData();
}
5.异常页面
图5
6.过滤跨站代码直接用的微软的AntiXss类库
model.Content = Microsoft.Security.Application.AntiXss.GetSafeHtmlFragment(this.tbContent.Text);
7.异常记录代码
通过Global.asax文件实现的
void Application_Error(object sender, EventArgs e)
{
// 在出现未处理的错误时运行的代码
string referrer = (Request.UrlReferrer != null) ? Request.UrlReferrer.AbsoluteUri : String.Empty;
CommonFunctions.LogsWrite(Server.MapPath("~/Logs/Logs.xml"),Request.Url.AbsoluteUri,System.DateTime.Now.ToString(),Request.UserHostAddress,Request.UserAgent,referrer,Server.GetLastError().GetBaseException().Message);
}
8.数据库连接代码
<add name="SQLCon" connectionString="Data Source=./SQLEXPRESS;AttachDbFilename=|DataDirectory|/SZCMS.MDF;Integrated Security=True;User Instance=True"/>
9.session超时时间设定 可以通过 Inproc 方式或者是通过StateServer方式
推荐StateServer，用InProc时session容易丢失
<sessionState timeout="60" mode="InProc"></sessionState>
<!--<sessionState timeout="10" mode="StateServer"></sessionState>-->
10.Session登陆验证用的httpModules处理
void context_AcquireRequestState(object sender, EventArgs e)
{
HttpApplication ha = (HttpApplication)sender;
if (ha.Context.Session == null)
return;
if (ha.Context.Session["AdminUser"] == null)
{
string str=ha.Context.Request.Url.AbsolutePath.ToLower();
if (str.IndexOf("/system") == 0 && str != "/system/login.aspx")
{
ha.Context.Response.Write("<script>alert('登录超时，请重新登录');top.location.href='/System/Login.aspx';</script>");
ha.Context.Response.End();
}
}
}
11.登录账号 admin SZCMS
