保存从jquery数组传递的多个输入文件的值

Question

我有一个包含多行的表，每行都有输入文件和一些其他文本输入，我想从jquery函数将这些数据传递给JsonResult，但我遇到问题所以我总是得到请求文件= 0

这是我的代码

function saveDocumentsData(researcherId) {
    debugger;
    var document = new Array();
    documents = new Array();
   $("#docsTable > tbody > tr").each(function () {
        var row = $(this);
        var id = row.find("span.id").html();
        var docId = row.find("span.docId").html();
        var docType = $("#docTypes" + id + " option:selected").val();
        var docDate = ($("#date" + id).datepicker('getDate'));
        var dFileUpload = $("#up" + id).get(0);
        var dFiles = dFileUpload.files;
        document =
        {
            "UpdateDate": thisDate, "IsActive": true, "UserId": userId,"JobResearcherId": researcherId,
            'JobResearcherDocumentsId': docId, 'JobResearcherDocumentTypesId': docType
            , 'DocumentRegisterDate': docDate.toISOString(), 'DocFiles': dFiles[0]
        };

       documents.push(document);

       });

    $.ajax({
     url: "@Url.Action($"AddResearcherDocuments", $"JobResearcher")",
        type: "POST",
        contentType: 'application/json',
        processData: false,
        data: JSON.stringify({
          researcherDocuments: documents
    }),
    success: function (data) {

    }
});
}

所有数据都是真实传递但输入文件。任何建议
