我发现了一个非常好的动作过滤器,它将逗号分隔的参数转换为泛型类型列表:http://stevescodingblog.co.uk/fun-with-action-filters/

我想使用它,但它不适用于ApiController,它完全忽略它.有人可以帮助转换它以供Web API使用吗？

[AttributeUsage(AttributeTargets.Method)]
public class SplitStringAttribute : ActionFilterAttribute
{
    public string Parameter { get; set; }

    public string Delimiter { get; set; }

    public SplitStringAttribute()
    {
        Delimiter = ",";

        if (filterContext.ActionParameters.ContainsKey(this.Parameter))
        {
            string value = null;
            var request = filterContext.RequestContext.HttpContext.Request;

            if (filterContext.RouteData.Values.ContainsKey(this.Parameter)
                && filterContext.RouteData.Values[this.Parameter] is string)
            {
                value = (string)filterContext.RouteData.Values[this.Parameter];
            }
            else if (request[this.Parameter] is string)
            {
                value = request[this.Parameter] as string;
            }

            var listArgType = GetParameterEnumerableType(filterContext);
