asp.net-mvc 在后期操作中获取字典或如何将 FormCollection 转换为字典

Question

有人知道如何将 FormCollection 转换为 IDictionary 或如何在后期操作中获取 IDictionary 吗？

Answer 1

这只是 Omnu 代码的等价物，但对我来说似乎更优雅：

Dictionary<string, string> form = formCollection.AllKeys.ToDictionary(k => k, v => formCollection[v]);

Answer 2

我是这样做的：

            var form = new Dictionary<string, string>();
            foreach (var key in formCollection.AllKeys)
            {
                var value = formCollection[key];
                form.Add(key, value);
            }

Answer 3

在 .Net Core 上，这个对我有用。

var collection = Request.Form.Keys.ToDictionary(k => k, v => Request.Form[v].ToString());

Answer 4

    public static IDictionary<string, string[]> GetFormParameters(FormCollection collection)
    {
        IDictionary<string, string[]> formParameters = new Dictionary<string, string[]>();
        foreach (var key in collection.AllKeys)
        {
            if (key == null) continue;
            var value = collection.GetValues(key);

            // value = CrossSiteAttackUtil.CleanHtml(value);
            if (value != null)
            {
                formParameters.Add(key, value);
            }
        }
