我是移动应用程序开发的新手.当我.xaml在新的解决方案中创建一个新文件时Xamarin Studio.
它给出了错误:
"目标"UpdateDesignTimeXaml"不退出".
我该如何解决这个问题？
我正在尝试从组件生成html内容很多时间,但是这个组件是从AppCompoment生成的.所以我想用routerLink从组件生成内容.我将在下面展示这个例子.知道我使用DeborahK从pluralsight.com教程获得的这个解决方案,我的源代码与此https://github.com/DeborahK/Angular2-GettingStarted/blob/master/APM - Final 相同.好的,让我们解释一下我的代码.
我有主index.html

<!-- HTML5 shim and Respond.js for IE8 support …我是脚本语言的新手.我用google搜索使用jQuery加载和解析JSON文件.我已经从Stack Overflow获得了那些链接的帮助.
我有这个名为的JSON文件new.json.
{ "a": [
{"name":"avc"},
{"name":"Anna"},
{"name":"Peter"},
{"Folder": "ABC", "name":[
{"name":"John"},
{"name":"Anna"},
{"Folder":"XYZ", "name":[
{"name":"fdgh"},
{"name":"hdfghh"},
{"Folder":"JKL", "name":[
{"name":"gdfgdfgggggg"},
{"name":"hddddddddddddddddddddddddddddh"},
{"Folder":"PQR", "name":[
{"name":"gddddddg"},
{"name":"ddhh"}
]
}
]
}
]
}
]
}
]
}
这是我加载new.json文件的代码jQuery/JavaScript代码.我在代码中写了我的<script>代码.
<script src="jquery-3.1.0.js"></script>
<script type="text/javascript" language="javascript" src="C:\Users\Girish\Desktop\new.json"></script>
<script type="text/javascript">
var out="<ul>";
var j=0;
function functionName(event) {
$('li[id^="foo"]').click(function(e){
e.stopPropagation();
var x = $(this).last().find(' > ul').clone().find('ul').remove().end();
$('#list').html(x);
$("#list .hide").show();
});
}
$(document).ready(function() {
$('li[id^="foo"]').each(function() {
$(this).on('click', {param: this.id}, functionName);
}); …所以基本上用户能够填写一个数字，该数字被添加到列表中，一旦用户按下按钮，列表应该在不使用该.Sort();功能的情况下进行排序
public int[] nummers;
public ObservableCollection<int> alleNummers = new ObservableCollection<int>();
public MainWindow()
{
InitializeComponent();
}
private void button_Click(object sender, RoutedEventArgs e)
{
alleNummers.Add(int.Parse(nummerBox.Text));
listBox.ItemsSource = alleNummers;
}
private void sortBtn_Click(object sender, RoutedEventArgs e)
{
foreach (int i in alleNummers)
{
//Sort the int's from small to big
}
nummers = alleNummers.ToArray();
listBox.ItemsSource = nummers;
}
我想，我需要使用循环foreach，但不知道要输入什么。顺便说一句，这是一个小作业。
如何在MVC中使用SqlDataReader使用Razor视图显示数据？我已经尝试过这样的事情。
控制器代码：-
public ActionResult UserDetails(DashBoard dash)
{
using (var cn = new SqlConnection(ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString))
{
String sql = "SELECT DU.UserRMN, MU.Name, DeptName, MgrID, TLeadID FROM Details_Users DU, Master_Users MU where DU.UserRMN=MU.UserRMN";
SqlCommand cmd = new SqlCommand(sql, cn);
cn.Open();
SqlDataReader rdr = cmd.ExecuteReader();
List<DashBoard> model = new List<DashBoard>();
while(rdr.Read())
{
var details = new DashBoard();
details.UserRMN = rdr["UserRMN"].ToString();
details.Name = rdr["Name"].ToString();
details.DeptID = rdr["DeptID"].ToString();
details.MgrID = rdr["MgrID"].ToString();
details.TLeadID = rdr["TLeadID"].ToString();
model.Add(details);
}
return View(model);
}
}
