C# 通过颜色字典查看MVC

我正试图从我的角度检索模型上的颜色词典。但是我得到一个错误，颜色字典不能被序列化。在我的模型中，我创建了如下列表

public Dictionary<int, Color> Colourlist = new Dictionary<int, Color>();

---

问题是您的字典不能有非字符串键，因为javascript无法正确理解它们。然而，在您的情况下，修复似乎足够简单-只需将您的字典转换为使用数字的字符串表示作为键的字典：

public Dictionary<string, Color> Colourlist = new Dictionary<string, Color>();

public Dictionary<string, Color> CreateColourPalette()
{
    Colourlist.Add("1", System.Drawing.ColorTranslator.FromHtml("#f2dcdb"));
    ...

public Dictionary colorlist=new Dictionary（）；
公共词典CreateColor调色板（）
{
colorlist.Add（“1”，System.Drawing.ColorTranslator.FromHtml（“#f2dcdb”）；
...

很抱歉，但是你真的需要学习一些JS。你目前编写的代码有点糟糕。我对javascript不太熟悉，所以它可能不是最好的，但是我认为堆栈溢出是为需要帮助的人准备的

function createTable()
        {

            var num_cols = 0;
            var headings = new Array();
            headings.push("Cost Type");
            var colours = @Html.Raw(Json.Encode(Model.Colourlist));
            var checkbox = $("input[name=SelectedYears]");
            for (var i = 0; i < checkbox.length; i++) {
                if (checkbox[i].checked) {
                    var chkBoxText = checkbox[i].nextSibling;
                    if (chkBoxText != null)
                        headings.push(chkBoxText.nodeValue);
                }
            }

            var num_cols = headings.length;
            var theader = '<table border="1">\n';
            var tbody = '';

            //create heading row
            tbody += '<tr>';
            for (var j = 0; j < headings.length; j++)
            {
                tbody += '<td style="margin-right:10px;">';
                tbody += headings[j].toString();
                tbody += '</td>'
            }

            var costtypes = $("input[name=SelectedCostTypes]")
            tbody += '</tr>\n';

            for( var i=0; i<costtypes.length;i++)
            {
                if (costtypes[i].checked) {
                    var chkCostTypeText = costtypes[i].nextSibling;
                    if (chkCostTypeText != null)

                        tbody += '</td>'
                        tbody += '</tr>\n';
                    }
                }
            }
            var tfooter = '</table>';
            document.getElementById('wrapper').innerHTML = theader + tbody + tfooter;
        }
