本文介绍如何在ASP.NET MVC中自定义Value Provider Factory，通过解析HTTP请求头和表单数据，实现对集合类的脚本提交。通过重写ValueProviderFactory的GetValueProvider方法，构造NameValueCollection并返回，确保数据正确传递给模型。

使用腳本提交集合类时，MVC binding

public class FormExtensionValueProviderFactory : ValueProviderFactory
    {
        public override IValueProvider GetValueProvider(ControllerContext controllerContext)
        {
            NameValueCollection requestData = new NameValueCollection();
            var headers = controllerContext.RequestContext.HttpContext.Request.Headers;
            foreach (string key in headers.Keys)
            {
                requestData.Add(key.Replace("-", ""), headers[key]);
            }
            var forms = controllerContext.RequestContext.HttpContext.Request.Form;
            foreach (string key in forms.Keys)
            {
                if (!string.IsNullOrEmpty(key))
                {
                    requestData.Add(ReplaceText(key), forms[key]);
                }
            }
            return new NameValueCollectionValueProvider(requestData, CultureInfo.InvariantCulture);
        }

        public string ReplaceText(string CommandText)
        {
            Regex reg = new Regex(@"(?<part1>(\S*)\[)(?<part2>(\d*)\])(?<part3>(\[\S*\]))", RegexOptions.IgnoreCase | RegexOptions.Multiline);
            var result = reg.Match(CommandText).Groups;

            if (result["part2"] != null && result.Count > 1)
            {
                string part1 = result["part1"].Value;
                string part2 = result["part2"].Value;
                string part3 = result["part3"].Value;
                return result["part1"].Value + result["part2"].Value
                     + result["part3"].Value.Replace("[", ".").Replace("]", "");
            }
            else
            {
                return CommandText;
            }
        }

    }

在 Application_Start 添加

ValueProviderFactories.Factories.Insert(0, new FormExtensionValueProviderFactory());
