javascript - 'IJsonHelper' 不包含 'Encode' 的定义

Question

我想在我看来将字符串列表转换为 javascript 数组，并且我在互联网上的几个地方找到了以下建议:

@model IEnumerable<DSSTools.Models.Box.BoxWhiteListUser>

@{
    var boxManager = new DSSTools.Managers.BoxManager();
    var allusers = boxManager.GetAllUsersAsync().Result.Entries.ToList().Select(u => u.Login);
}

@section Scripts {
    <script>
        var sourcearray = null;

        $(document).ready(function () {
            var arr = JSON.parse('@Html.Raw(Json.Encode(@allusers))');
        });
    </script>
}

但是，我只是觉得很烦

'IJsonHelper' does not contain a definition for 'Encode' and no extension method 'Encode' accepting a first argument of type 'IJsonHelper' could be found (are you missing a using directive or an assembly reference?)

这怎么可能？

我也试过直接打电话

var arr = JSON.parse('@Html.Raw(allusers)');

但是我在控制台中得到了这个错误

VM189:1 Uncaught SyntaxError: Unexpected token S in JSON at position 0
    at JSON.parse (<anonymous>)
    at HTMLDocument.<anonymous> (whitelist:107)

Answer 1

我设法用

做了我需要做的事

sourcearray = JSON.parse('@Html.Raw(Json.Serialize(allusers))');
