c# - 错误 : No overload for method "ToString" takes 1 arguments

Question

我正在尝试按特定顺序格式化日期

Time = DateTime.Parse(p.Time.ToString("dd-MM-yyyy HH:mm:ss"))

Time 的数据类型是DateTime

但是我收到了这个错误:

No overload for method "ToString" takes 1 arguments.

p 是我从中获取时间的表的对象。

  List<ProductImageMapWrapper> lstpm = new List<ProductImageMapWrapper>();
  lstpm = _db.ProductImageMaps.Where(i => i.ClientId == null && i.BrandId == null).Select(p => new ProductImageMapWrapper
  {
  Time= // Problem here
  }

现在，我尝试这样使用它

Time = DateTime.Parse(string.Format("{dd-MM-yyyy HH:mm:ss}", p.Time))

但是我得到了这个错误:

LINQ to Entities does not recognize the method System.DateTime Parse(System.String) method, and this method cannot be translated into a store expression.

Answer 1

String Time = Convert.ToDateTime(p.Time).ToString("dd-MM-yyyy HH:mm:ss");
