我想在Controller中为我的模型设置一个默认值,但它无法在创建页面中显示.
TestModel代码:
public class TestModel
{
[DataType(DataType.DateTime), Required]
[DisplayFormat(DataFormatString = "yyyy/MM/dd", ApplyFormatInEditMode = true)]
public DateTime StartTime { get; set; }
[DataType(DataType.DateTime), Required]
[DisplayFormat(DataFormatString = "yyyy/MM/dd", ApplyFormatInEditMode = true)]
public DateTime EndTime { get; set; }
public string Description { get; set; }
}

model.StartTime = DateTime.Now;
model.EndTime = DateTime.Now.AddDays(10);

return View(model);
