小编kbv*_*hnu的帖子

问题是标题本身.我是MVC的新手,现在我正在学习自学.请给我答案,这对于MVC更新鲜是明确的.谢谢.

我是LINQ的新手.

playerData是一个list<DataAccess.Team>,我想初始化另一个playerViewModelList包含数据的列表playerData.

我试过了foreach.

 foreach (DataAccess.Team dataTeam in playerData)
 {
     playerViewModelList.Add(new PlayersViewModel
     {
         PicPath = dataTeam.Tied.ToString(),
         PlayerID = (int)dataTeam.ID,
         PlayerName = dataTeam.TeamName
     });
  }

是否可以使用LINQ实现相同的功能？

我有一个html表，我需要获取第一行的值或文本（不是thead部分，它将在tbody部分中）。我需要点击按钮的值btnAdd

 <table>
    <thead>
    <tr>
    <td>Name</td>
    <td>ID</td>
    </tr>
    </thead>
    <tbody>
    <tr>
    <td>Edwin</td>
    <td><span style='display:none'>1</span></td>
    </tr>
    </tbody>
    </table>
   <input type='btnAdd' runat='server' >

我有一个aspx页面,我需要response.redirect到同一页面.我点击按钮时正在做.我可以在javascript中做到这一点.

我试过了window.location=url;.我想知道如何<% Response.Redirect(url) %>在javascript中调用？

I am having a start time,start date and end date,end time on my web page.I need to ensure that if the start date and end date is equal then the end time must be greater than start time and if end date is greater than start date then user can able to enter any time.How can I achieve this validation?

这是我的global.asax(注册路线)

  routes.MapRoute("NewDatabase",
             "Server/{serverId}/Instances/{instanceId}/NewDatabase/",
             new { controller = "Server", action = "NewDatabase" }
             );

            routes.MapRoute(
           "Instance",
           "Server/{id}/Instances/{instanceId}/Databases",
           new { controller = "Server", action = "Databases", id = "id",instanceId="instanceId" }
           );

            routes.MapRoute(
           "Database",
           "Server/{id}/Instances",
           new { controller = "Server", action = "Instances", id = "id" }
           );

如果xyz.com/Server/12/Instance/1/NewDatabase将是服务器的reuested URL, Server/{serverId}/Instances/{instanceId}/NewDatabase/将是匹配模式.我怎么知道上述请求匹配哪个条目？

谢谢

我的sql程序是

 SET @query='UPDATE '+@tbl+' SET  auth_Date='''+@authDate+'''
    ,authorized_By_ID=@AuthID
    ,authorized=1 WHERE '+@col+'=@Id;
    IF(@@ERROR=0) SET @reVal=1 ELSE SET @reVal=-1' 


    EXECUTE sp_executesql @query, N'@reVal int OUTPUT', 
    @reVal,N'@AuthID int',@AuthID,N'@Id int',@Id

这里@AuthID是Datetime,@ AuthID和@Id是int

1)我如何传递参数.2)有一个错误即将来临 Conversion failed when converting date and/or time from character string.

我有这个错误 No default member found for type 'VB$AnonymousDelegate_0(Of SqlDataReader,String,Object)'.

我的代码如下

dsBranch.Tables.Add(GetDataTableFromSQLReader(dr, "")) -打电话

Private Function GetDataTableFromSQLDataReader(ByVal dr As SqlDataReader, ByVal TableName As String)
    Dim dt As New DataTable(TableName)
    dt.Load(dr)
    Return dt
End Function
Dim GetDataTableFromSQLReader = Function(dr As SqlDataReader, TableName As String) GetDataTableFromSQLDataReader(dr, TableName)

这是我的班级

Public Class DBServer
    Public  ServerId  As Integer
    Public  ServerName As String
End Class

和变量:

Dim serverList As New List(Of DBServer)

在C#中.我可以这样添加:

serverList.Add(new DBServer{ ServerId=1,ServerName="Server1"});

我怎样才能在VB.NET中实现这一点.我使用的是.NET 4.0.

这是我的代码块

   XY = xyList.[Select](Function(o) New XY() With {.y = New y() With {.xId = o.x.Id _
            , .xName = o.x.xName} _
            , .Stopped = o.Stopped _
            , .PNumber = o.PNumber _
            , .yId = o.yId _
            , .yName = o.yName _
         'need to add some comment here '
            , .Allocated = o.Allocated _
            , .TotalNo = o.TotalNo _
            }).ToList()

但是我尝试了'它的编译问题.

我需要在这个问题之间加以评论

谢谢

我正在使用parentNode.nextElementSibling.value访问复选框的兄弟;它将返回值并在Firefox中正常工作.但在IE中它表示对象为空并且说

Microsoft JScript运行时错误:'parentNode.nextElementSibling.value'为null或不是对象

我的功能如下

   function chkEnergy() {
             var inputs = $('.check input');
            var count = 0;var ok = 1;
        for (var i = 0; i < inputs.length; i++) {
            //alert(inputs[i].attr('checked'));
            if (inputs[i].checked == true) {
                var ch = inputs[i];
                var qty=ch.parentNode.nextElementSibling.value;
                if (qty == "0") {
                    ok = 0;
                    showStatus(true, "Please specify the Quantity");
                    return false;
                }
                else {
                    ok = 1;
                    continue;
                }
            }
        }
            if(ok==1)
                return true
            else
              return false;

     }

我使用这种方式将dataList放在复选框和文本框中

     <asp:DataList ID="dlstEnergyItems" runat="server" RepeatColumns="4" RepeatDirection="Horizontal"  Width="100%"> …

有没有办法转换这个？

public int? intVal ;
public double? dblVal ;

我现在的工作方式

if(dblVal==null)
    intVal =null;
else
    intVal = Convert.ToInt32(dblVal);

还有其他办法吗？提前致谢 .
