C＃服务器数组到客户端/ javascript

Question

This has probably been asked before but I can't seem to find any answers that I can get to work.

I have a SQL query that produces five rows of data in the backend. And I then fetch the data from the query like so:

   if (reader.HasRows) {
    var list = new List < GetUserNames > ();
    // Read advances to the next row.
    while (reader.Read()) {
     //Person p = new Person();
     // To avoid unexpected bugs access columns by name.

     //Convert.ToInt32(dataReader.GetValue(3));
     wholeAvg = Decimal.Round(reader.GetDecimal(reader.GetOrdinal("wholeavg")), 2);

     list.Add(new GetUserNames {
      users = reader.GetString(2)
     });
     allRecords = list.ToArray();

    }

   }

Now what I would like to send to the client and use with javascript is the allRecords array. Can someone point me in the right direction how to get the array from the backend?

Thanks!

Answer 1

如果使用的是MVC，则可以将'​​allrecords'添加到TempData并使用以下代码；

var records = @Html.Raw(Json.Encode(TempData["Records"]))

Answer 2

You could serialize it to JSON then store the value in a hidden input. In your javascript you can then pick up the value of that field:

.cs:

var json = JsonConvert.SerializeObject(allRecords);
hdUsers.Value = json;

.aspx:

<asp:HiddenField runat="server" ID="hdUsers"/>

<script type="text/javascript">

var jsonString = $("[id$='hdUsers']").val()

var arr = JSON.parse(jsonString);

</script>
