最近由于大势所逼！想认真学习一下ASP.net ，请高手帮个忙，给段初学者能看的代码

我只有一点ASP的基础（vbs）我想找段能看懂的aspx代码，最好是VB的，因为我对C#不熟悉谁能给我段简单的注册的页面或者登录验证帐号密码的页面

解决方案 »

  1.   

    if (txtUser.Text.Trim() == "")
    {
    Sys.ShowMessage(this, "您不能输入空的用户名！");
    return;
    } DataSet dstTemp = Sys.SysManager.GetUser(txtUser.Text.Trim(), txtPassWord.Text.Trim()); if (dstTemp == null)
    {
    Sys.ShowMessage(this, "您输入的用户或密码有误！");
    return;
    } //将输入的用户存在Session中，包含了用户的相关信息和可以使用的模块名称
    userEnety us = new userEnety();
    us.logid = dstTemp.Tables[0].Rows[0]["LogID"].ToString().Trim();
    us.logname = dstTemp.Tables[0].Rows[0]["LogName"].ToString().Trim();
    us.userCode = dstTemp.Tables[0].Rows[0]["UserCode"].ToString().Trim();
    us.userName = dstTemp.Tables[0].Rows[0]["UserName"].ToString().Trim();
    us.deptCode = dstTemp.Tables[0].Rows[0]["DeptCode"].ToString().Trim();
    us.deptName = dstTemp.Tables[0].Rows[0]["DeptName"].ToString().Trim();
    us.rybh = dstTemp.Tables[0].Rows[0]["Rybh"].ToString().Trim();

    。
    这适合不懂.net的人吗？

    }
    }
    }
    呵呵呵
      

  7.   

    是不是ASP.NET都是用c#写的啊，都不用vb了？
      

  8.   

    如果你一点.net基础都没有，看起来都会困难的.
    不如买本书看看啊。
      

  9.   

    书我是有的，但不知道看了会不会很有用
    因为感觉asp.net和asp完全是两个概念  还有点不适应

    Sys.ShowMessage(this, "您不能输入空的用户名！");
    提示找不到类型或命名空间啊！sys

    我想这是很容易懂，也是对asp.net结构的理解有一定的帮助！
