我无法弄清楚为什么我的视图只将模型的NULL传回给我的控制器.
这适用于Edit Post方法.我使用Edit Post方法检查了其他控制器,其结构与此相同,并且它们工作正常.它似乎只是这个视图和控制器.

这是我的观点：
@H_301_5@@model Non_P21_Quote_System_v1._0.Models.gl_code @{ ViewBag.Title = "Edit"; Layout = "~/Views/Shared/_Layout.cshtml"; } <h2>Edit</h2> @if (TempData["Message"] != null) { <div style="color:green"> @TempData["Message"] </div><br /> } @if (ViewBag.error != null) { <div style="color:red"> <h3>@ViewBag.error</h3> </div><br /> } @using (Html.BeginForm()) { @Html.AntiForgeryToken() <div class="form-horizontal"> <h4>gl_code</h4> <hr /> @Html.ValidationSummary(true,"",new { @class = "text-danger" }) @Html.HiddenFor(model => model.ID) <div class="form-group"> @Html.LabelFor(model => model.GL_code,"GL Code",htmlAttributes: new { @class = "control-label col-md-2" }) <div class="col-md-10"> @Html.EditorFor(model => model.GL_code,new { htmlAttributes = new { @class = "form-control" } }) @Html.ValidationMessageFor(model => model.GL_code,new { @class = "text-danger" }) </div> </div> <div class="form-group"> @Html.LabelFor(model => model.GL_description,"Gl Description",htmlAttributes: new { @class = "control-label col-md-2" }) <div class="col-md-10"> @Html.EditorFor(model => model.GL_description,new { htmlAttributes = new { @class = "form-control" } }) @Html.ValidationMessageFor(model => model.GL_description,new { @class = "text-danger" }) </div> </div> <div class="form-group"> @Html.LabelFor(model => model.expense_type_ID,"Expense",htmlAttributes: new { @class = "control-label col-md-2" }) <div class="col-md-10"> @Html.DropDownList("expense_type_ID",null,htmlAttributes: new { @class = "form-control" }) @Html.ValidationMessageFor(model => model.expense_type_ID,new { @class = "text-danger" }) </div> </div> <div class="form-group"> @Html.LabelFor(model => model.eag,"Employee Account Group",htmlAttributes: new { @class = "control-label col-md-2" }) <div class="col-md-10"> @Html.DropDownList("eag",htmlAttributes: new { @class = "form-control" }) @Html.ValidationMessageFor(model => model.eag,new { @class = "text-danger" }) </div> </div> <div class="form-group"> <div class="col-md-offset-2 col-md-10"> <input type="submit" value="Save" class="btn btn-default" /> </div> </div> </div> } <div> @Html.ActionLink("Back to List","gl_Index") </div> @section Scripts { @Scripts.Render("~/bundles/jqueryval") }这是我的控制器方法：
@H_301_5@[HttpPost] [ValidateAntiForgeryToken] public async Task<ActionResult> Edit([Bind(Include = "ID,GL_code,GL_description,expense_type_ID,eag")] gl_code gl_code) { if (ModelState.IsValid) { db.Entry(gl_code).State = EntityState.Modified; await db.SaveChangesAsync(); return RedirectToAction("gl_Index"); } ViewBag.eag = new SelectList(db.employee_account_group,"ID","eag_name"); ViewBag.expense_type_ID = new SelectList(db.expense_type,"type",gl_code.expense_type_ID); return View(gl_code); }当我调试它时,我看到传入的模型的值为NULL.我在控制器端看到这个在Edit方法的参数部分.
