我是Asp.net MVC的新手，目前我想在用户点击操作链接按钮时将一些参数（选定日期）传递给控制器，下面是操作链接和日期选择器字段代码，
<div class="panel panel-default">
<div class="panel-heading">
<h3 class="panel-title">
Manage Outward - Completed</h3>
</div>
<div class="panel-body">
@Html.CreateJQGrid(Model.GridCompletedOWData)
<br />
<div class="icon-list">
@Html.ActionLink("Download Completed Transactions", "ExportToExcelOutwardCompleted", "InwardOutward", new { enctype = "multipart/form-data", model = @Model, FromDate = @Model.DownloadOutwardFromDate.ToString(), ToDate = Model.DownloadOutwardFromDate.ToString() }, new { @id = "DownloadAccount", @class = "linkTxt" })
</div>
</div>
<div class="col-md-3">
<label for="" class="control-label">
Download From Date
</label>
@Html.EditorFor(model => model.DownloadOutwardFromDate, new { @class = "form-control" }).DisableIf(() => Model.IsReadOnly == true)
@Html.HiddenFor(model => model.DownloadOutwardFromDate)
</div>
<div class="col-md-3">
<label for="" class="control-label">
Download To Date
</label>
@Html.EditorFor(model => model.DownloadOutwardToDate, new { @class = "form-control" }).DisableIf(() => Model.IsReadOnly == true)
@Html.HiddenFor(model => model.DownloadOutwardToDate)
</div>
<br />
</div>
我的控制器，
public ActionResult ExportToExcelOutwardCompleted(CompletedIWOWDetailsModel model, string FromDate, string ToDate)
{
var employeeBranch = employeeBranchService.FilterBy(x => x.Userseq == LoggedInUser.UserSeqeunce).Select(x => x.Branchseq).ToList();
var userIds = employeeBranchService.FilterBy(x => employeeBranch.Contains(x.Branchseq)).Select(x => x.Userseq).ToList();
List<TrnOutflowDetailsAud> trnInflowDetailsP = trnOutwardDetailsAudService.FilterBy(x =>
(employeeBranch.Contains(x.InitiatedBranchSeq) && (x.OutflowStage == (int)enumOutflowStage.Completed) && x.Transactiondate >= DateTime.Now.AddDays(-30))).ToList();
var clientDCAList = clientDcaService.All().Where(x => x.Active == "Y").ToList();
var List = (from p in trnInflowDetailsP.ToList()
join C in GetCurrency() on p.Currencyoftheinstructedamount equals C.Id into CTClist
from C in CTClist.DefaultIfEmpty()
join CC in GetCurrency() on p.Currencyofthetransaction equals CC.Id into CTC
from CC in CTC.DefaultIfEmpty()
join PC in GetPurposeCode() on p.PurposeCodeSeq equals PC.Id into PurLIST
from PC in PurLIST.DefaultIfEmpty()

//join D in GetDepartmentList() on p.DepartmentSeq equals D.Id into DEPList
//from D in DEPList.DefaultIfEmpty()
join b in branchService.All().ToList() on p.BranchSeq equals b.Id into branch
from b in branch.DefaultIfEmpty()
join IB in branchService.All().ToList() on p.InitiatedBranchSeq equals IB.Id into IBList
from IB in IBList.DefaultIfEmpty()
//join CTC in clientDCAList on p.AccountNumber equals CTC.AccountNo into CTCList
//from CTC in CTCList.DefaultIfEmpty()
select new
{
p.TranRef,
TradeStatus = p.OutflowStage == 0 ? "" : ((enumOutflowStage)p.OutflowStage).GetDescriptionEnum(),
InitiatedBranchName = IB == null ? "" : IB.BranchName,
p.Draccountnumber,
BranchName = b == null ? "" : b.BranchName,
TransactionDate = p.Transactiondate.GetFormatDateWithOutTime(),
p.CustomerName,
p.Noofinstructions,
p.Amount,
CurrencyOfTheInstructedAmount = C == null ? "" : C.CurrencyCode,
CurrencyOfTheTransaction = CC == null ? "" : CC.CurrencyCode,
PurposeCode = PC == null ? "" : PC.PurCode,
ProductName = p.ProductName == 0 ? "" : ((enumOutflowProductNames)p.ProductName).GetDescriptionEnum(),
p.ProductNameOthers,
p.Anyotherspecificinstruction,
Modeoftransaction = p.Modeoftransaction == null ? "" : ((enumModeOfTransaction)p.Modeoftransaction).GetDescriptionEnum(),
SignatureVerification = p.SignatureVerification.GetYesNoString(),
Callback = p.Callback.GetYesNoString(),
p.IdmsRefNo,
//p.BatchNo,
p.Remarks,
Active = p.Active.GetYesNoString(),
//p.Status,
CreateUserName = CU == null ? "" : CU.UserName,
CreateDate = p.CreateDate.GetFormatDateWithOutTime(),
p.CreatorRemarks,
AuthUserName = AU == null ? "" : AU.UserName,
AuthDate = p.AuthDate.GetFormatDateWithOutTime(),
p.AuthRemarks
}).ToList();
ExcelPackage excel = new ExcelPackage();
var workSheet = excel.Workbook.Worksheets.Add("Sheet1");
workSheet.Cells[1, 1].LoadFromCollection(List, true);
using (var memoryStream = new MemoryStream())
{
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AddHeader("content-disposition", "attachment; filename=" + Constants.Controller.InwardOutward + ".xlsx");
excel.SaveAs(memoryStream);
memoryStream.WriteTo(Response.OutputStream);
Response.Flush();
Response.End();
}
return View();
}
现在我想将选定日期（DownloadOutwardFromDate）作为参数传递给ExportToExcelOutwardCompleted方法。但是每当我单击actionlink按钮时，FromDate参数为null或默认日期值，无法获取选定值。所以请任何一个给出解决方案

将模型直接传递给动作。在代码隐藏中的操作中，直接读取这些字段。
修改操作的签名，使其可以作为模型的参数。

要提交用户输入的值，您必须使用form。 form可以设置为POST或GET。
示例
视图
@using (@Html.BeginForm("ExportToExcelOutwardCompleted", "InwardOutward", FormMethod.Get))
{
@Html.TextBox("dateFrom")
@Html.TextBox("dateTo")
<button type="submit">Submit</button>
}
控制器操作
public ActionResult ExportToExcelOutwardCompleted(string dateFrom, string dateTo)
{
// Your code here
return View();
}
文本框的id设置为与action方法中的参数相同的名称。这样，模型绑定可以正确关联请求中的数据。
