Question

Index.cshtml code for text box
 @Html.LabelFor(m => m.ValidFromDate, "ValidFromDate")
     @Html.TextBoxFor(m => m.ValidFromDate)

我不知道如何将此文本框值插入数据库

Answer 1

假设您在数据库中有一个表名用户。首先，我们将创建一个POCO，它将代表此表，如下所示：

public class User
{
    public string Username { get; set; }
    public DateTime ValidFromDate { get; set; }
    //more propteries
}

现在让我们假设我们有一个名为Create的视图。在此视图中，您将通过我们已创建的User类作为您的模型。所以你的观点看起来应该是这样的。

@model Models.User

@{
ViewBag.Title = "User";
}

<div>
@using (Html.BeginForm("Create", "User"))
{
    @Html.AntiForgeryToken()

    @Html.LabelFor(m => m.Username)
    @Html.TextBoxFor(m => m.Username)

    @Html.LabelFor(m => m.ValidFromDate)
    @Html.TextBoxFor(m => m.ValidFromDate) 

    <button type="submit">Submit</button>
}
</div>

现在，您希望在控制器操作中获取此视图中的所有值。我们将继续创建名为UserController的控制器，在此控制器中，我们将GET和POST方法提供Create

//This is our GET action for the view 
public ActionResult Create()
{
   User user = new User();

   return View(user); //we pass in the user object to the view
}

[HttpPost]
[ValidateAntiForgeryToken]
//when you click submit this is the action that will get hit
public ActionResult Create(User model)
{
   if (!ModelState.IsValid)
       return View(model);

   string userName = model.Username;
   DateTime validFrom = model.ValidFromDate;

   //save to db here. I'm not sure if you're making direct calls or using entity framework or similar framework

   return RedirectToAction("Index", "Home"); //this will redirect the user to home. You can return a view or redirect user somewhere else.
}

我们走了。我测试了它，它返回了模型属性以及发布的文件。

DECLARE @Tables TABLE
(
    myTableName VARCHAR(500)
)

insert into @Tables(myTableName) values ('WorkOrderMasterAttachments');
insert into @Tables(myTableName) values ('BillOfMaterialAttachments');
insert into @Tables(myTableName) values ('CustomerAttachments');
insert into @Tables(myTableName) values ('ToolAttachments');
insert into @Tables(myTableName) values ('FacilityAttachments');
insert into @Tables(myTableName) values ('LocationAttachments');
insert into @Tables(myTableName) values ('AssetAttachments');
insert into @Tables(myTableName) values ('ContractorAttachments');
insert into @Tables(myTableName) values ('VendorAttachments');
insert into @Tables(myTableName) values ('WorkOrderAttachments');
insert into @Tables(myTableName) values ('ClosedWorkOrderAttachments');
insert into @Tables(myTableName) values ('EmployeeAttachments');
insert into @Tables(myTableName) values ('PurchaseOrderAttachments');
insert into @Tables(myTableName) values ('PurchaseOrderHistoryAttachments');
insert into @Tables(myTableName) values ('PartAttachments');
insert into @Tables(myTableName) values ('AssetSystemAttachments');

declare @SQL nvarchar(max) = ''

select @SQL = @SQL + 'Update ' + myTableName + ' set Path = REPLACE(Path,@oldPath,@newPath);'
from @Tables

select @SQL

exec sp_executesql @SQL, N'@oldPath varchar(500), @newPath varchar(500)', @oldPath = @oldPath, @newPath = @newPath

- 这是我用来绑定表单的模型

//-- this is the controller
    public class FileUploadDemoController : Controller
    {
        //
        // GET: /FileUploadDemo/

        public ActionResult Index()
        {
            return View();
        }

        -- here you can name the method as you like to I justuse postform
        [HttpPost]
        public ActionResult PostForm(FileUploadModel model)
        {
            Request.Files is the object which contrins all files which you posted from the form when you hit submit buuton after selecting excel file.
            if (Request.Files != null && Request.Files.Count > 0)
            {
               // here you have files attached and model propertied now you can go to db and perform operation which you need to do 
            }

            return View("Index", model);
        }
    }

- 最后是cshml文件。导入点是在BeginForm中使用新的{enctype =“multipart / form-data”}。

        namespace WebApplication1.Models
    {
        public class FileUploadModel
        {
            public string Name { get; set; }
            public string ValidFromDate { get; set; }
        }
    }

//如果您输入01-01-2015这样的日期进行测试，请不要使用任何日期票据来保持简单。

          // the page from where you will post the data . Please change you model class in place of FileUploadModel I created ot for me .
