如何将多个参数传递到MVC控制器，包括字符串列表/字符串数组? [英] How to pass multiple parameters to MVC controller including list/array of strings?

问题描述

我有一个ajax调用，我正在尝试将字符串数组以及id和search参数发布到控制器.有人能告诉我该怎么做吗? 示例:

I have a ajax call and I'm trying to post an array of strings, as well as an id and search parameter to a controller. Anyone able to show me how to do this? Example:

jQuery

jQuery

$("body").on("click", "#btnClientModalSearch", function (e) {
    preventDefaultAction(e);
    var url = GetUrlPath() + "/Client/GetClientCalendarSearchResults";
    var searchTypeId = $("#ddlSearchType").val();
    var searchParameter = $("#tbSearchParameter").val();
    var diaryId = $("#SelectedEventId").val();
    var values = [];
    $(".referralIdList").each(function () {
        var referralId = $(this).attr("id");
        var arr = referralId.split('referralId');
        values.push(arr[1]);
    });
    var postData = { alreadyAddedReferralIds: values };
    $.ajax({
        url: url,
        data: { searchTypeId: searchTypeId, searchParameter: searchParameter, diaryId: diaryId, alreadyAddedReferralIds: postData },
        cache: false,
        type: "POST",
        success: function (result) {
            if (result.success === true) {
                $("#searchResultsPlaceHolder").html(result.view);
            }
        },
        error: function (responseText, textStatus, errorThrown) {
            alert('Error - ' + errorThrown);
        }
    });
});

控制器

Controller

 public JsonResult GetClientCalendarSearchResults(string searchTypeId, string searchParameter, string diaryId, List < string > alreadyAddedReferralIds) {}

当我尝试此操作时， alreadyAddedReferralIds 在控制器上始终为空.

When I try this, the alreadyAddedReferralIds is always empty at the controller.

推荐答案

尝试用单个对象参数替换控制器中的参数.所以你会有类似的东西:

Try replacing the parameters in the controller with a single object parameter. So you would have something like:

public JsonResult GetClientCalendarSearchResults(SearchResultsRequest request)

public class SearchResultRequest
{
   public string searchTypeId { get; set; } 
   public string searchParameter { get; set; } 
   public string diaryId { get; set; } 
   public List<string> alreadyAddedReferralIds { get; set; }
}

从我的经验发布到需要多个参数的操作方法，不会填充其值.

From my experience posting to an action method that requires multiple parameters won't have their values populated.
