我想让用户只在两个字符串中选择一个,Internal或Consigned,插入到数据库的InternalConsigned列中。我该怎么做呢?这是我当前的代码:
Equipment.cs模型类:
public class Equipment
{
[Key]
public int Id { get; set; }
[Required]
[DisplayName("Equipment Name")]
public string Name { get; set; }
[Required]
public int Amount { get; set; }
[Required]
public string Status { get; set; }
[ForeignKey("DepartmentId")]
public int DepartmentId { get; set; }
public Department? Department { get; set; }
[Required]
public string InternalConsigned { get; set; }
public DateTime EOLDate { get; set; }
}
创建操作方法:
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Create([Bind("Id,Name,Amount,Status,DepartmentId,InternalConsigned,EOLDate")] Equipment equipment)
{
if (ModelState.IsValid)
{
_context.Add(equipment);
await _context.SaveChangesAsync();
return RedirectToAction(nameof(Index));
}
ViewData["DepartmentId"] = new SelectList(_context.Departments, "Id", "Name", equipment.DepartmentId);
return View(equipment);
}
Create.cshtml:
@model Equipment
@{
ViewData["Title"] = "Create";
}
<h4>Equipment</h4>
<hr />
<div class="row">
<div class="col-md-4">
<form asp-action="Create">
<div asp-validation-summary="ModelOnly" class="text-danger"></div>
<div class="form-group">
<label asp-for="Name" class="control-label"></label>
<input asp-for="Name" class="form-control" />
<span asp-validation-for="Name" class="text-danger"></span>
</div>
<div class="form-group">
<label asp-for="Amount" class="control-label"></label>
<input asp-for="Amount" class="form-control" />
<span asp-validation-for="Amount" class="text-danger"></span>
</div>
<div class="form-group">
<label asp-for="Status" class="control-label"></label>
<input asp-for="Status" class="form-control" />
<span asp-validation-for="Status" class="text-danger"></span>
</div>
<div class="form-group">
<label asp-for="DepartmentId" class="control-label"></label>
<select asp-for="DepartmentId" class ="form-control" asp-items="ViewBag.DepartmentId"></select>
</div>
<div class="form-group">
<label asp-for="InternalConsigned" class="control-label"></label>
<input asp-for="InternalConsigned" class="form-control" />
<span asp-validation-for="InternalConsigned" class="text-danger"></span>
</div>
<div class="form-group">
<label asp-for="EOLDate" class="control-label"></label>
<input asp-for="EOLDate" class="form-control" />
<span asp-validation-for="EOLDate" class="text-danger"></span>
</div>
<div class="form-group">
<input type="submit" value="Create" class="btn btn-primary" />
</div>
</form>
</div>
</div>
我知道我必须在视图中使用select标记,但我不确定在控制器中写入什么。

如果我没有误解你的问题,你想写一个下拉列表两个选项
Internal
或Consigned
,所以你可以参考这个简单的演示,希望它能帮助你.然后在视图中:
