Question

我必须比较两个相同类的列表，并将差异存储在一个字符串中。

public class SomeCustomClass {
      public int MaterialId { get; set; }
      public string CwNumber { get; set; }
      public string MaterialName { get; set; }
      public List<MyClass1> ListMyClass { get; set; }

      public SomeCustomClass() {
        ListMyClass = new List<MyClass1>();
      }      
   }

 static void Main() {
    SomeCustomClass a = new SomeCustomClass();
    SomeCustomClass b = new SomeCustomClass();
    a.CwNumber = "A";
    a.MaterialId = 1;
    a.MaterialName = "Material1";
    a.ListMyClass.Add( new MyClass1 { id = 11,Name="John" });
    a.ListMyClass.Add(new MyClass1 { id = 12, Name = "Naren" });       

    b.CwNumber = "A";
    b.MaterialId = 2;
    b.MaterialName = "Material2";
    b.ListMyClass.Add(new MyClass1 { id = 11, Name = "Tamsan" });
    b.ListMyClass.Add(new MyClass1 { id = 12, Name = "Naren" });
    b.ListMyClass.Add(new MyClass1 { id = 13, Name = "sanjy" });
}

现在我必须比较 a.ListMyClass 和 b.ListMyClass 并将差异存储为

   id = "11",
   Name="John":id = 11,
   Name = "Tamsan" | id = "",
   Name="":id = 13,
   Name = "sanjy"

差异输出将包含 -

   i. Name is different for an ID.
   ii. An object exists in first list but not present in 2nd list.( in that case out put string will be like id="someid",Name="somename":id="",Name="").     
   iii. An object present in 2nd list is not present in 1st list.  (in that case out put string will be like id="",Name="":id="someid",Name="somename").

这将解决它，但它并不漂亮

                uniqueIDs += "id=\"\", Name=\"\" : " + element2;
            }

            return commonIDsDifferentNames + " | " + uniqueIDs;
        }
    }
