使用动态colNames和colModel时colnames <> colmodel的长度

Question

在我的MVC jqgrid代码中，colnames和colmodel返回相同长度的col。但是当运行应用程序时，我收到此错误。有什么帮助吗？

代码：

public WeekColumns GetWeekColumns(DateTime start, DateTime end)
    {
        WeekColumns week = new WeekColumns();

        string sWeekDate = string.Empty;

        var model = db.GetWeek(start.ToString("MM/dd/yyyy"),
            end.ToString("MM/dd/yyyy")).ToList().Select(s => s.WeekDate.ToString());

        IEnumerable<string> sModel = new List<string>();
        sModel = model;

        string sColumnNames = "['ID', 'Account', 'Lob'";

        foreach (string item in sModel)
            sColumnNames += ", 'C" + item.ToString().Replace("/", "_").Trim() + "'";

        sColumnNames += ", 'Report']";

        string sColumnModels = "[{ name: 'ID', key: true, hidden: true }, ";
        sColumnModels += "{ name: 'Account', width: 150, align: 'center' }, ";
        sColumnModels += "{ name: 'Lob', width: 150, align: 'center' }";

        foreach (string item in sModel)
            sColumnModels += ", { name: 'C" + item.ToString().Replace("/", "_").Trim() + 
                "', width: 150, editable: true}";

        sColumnModels += ", { name: 'Report', width: 150, align: 'center' }]";

        week.ColumnName = sColumnNames;
        week.ColumnModel = sColumnModels;

        return week;
    }

js：

$.ajax({
        url: "Staffing/GetWeekDate",
        type: 'POST',
        dataType: 'json',
        contentType: "application/json",

的价值colNames和colModel应数组大小相同的项目。看来你当前的代码尝试分配字符串中包含的文字"['ID', 'Account', 'Lob', ...]"和"[{ name: 'ID', key: true, hidden: true }, ...]"。jqGrid的哪尝试比较的项目在数量的代码阵列 colNames和colModel（见这里）比较的长字符串，你作为值使用colNames和colModel。因此，显示的消息是正确的，但是您的输入数据仍然错误。

因此，要解决该问题，您必须修复and 的格式（更改类型）。data.ColumnNamedata.ColumnModel

例如，您可以替代'的data.ColumnName和data.ColumnModel来\"。它使字符串成为正确的JSON格式，您可以使用$.parseJSON()（我的意思是colNames: $.parseJSON(data.ColumnName), colModel: $.parseJSON(data.ColumnModel)）。
