根据列属性值获取属性值
List<MyModel1> myModel1 = new List<MyModel1>();
MyUserModel myUserModel = new MyUserModel();
List<MyModel2> myModel2 = new List<MyModel1>();
myModel1 = m_Service1.GetMyModelFields();
myUserModel = m_Service2.GetMyUserDetails();
myModel2 = (from myModel1Field in myModel1
select new MyModel2 { FieldCaption = myModel1Field.FieldAlias,
FieldValue = "" }).ToList<MyModel2>();
myModel1Field.FieldAlias 文本将与 myUserModel 中的属性之一的 Column 属性之一的值相同。因此,我必须在 myUserModel 中搜索列 atribute(Name) 并获取相应的属性值并将其分配给“FieldValue”。如果我在 myUserModel 中找不到该值,我可以将“FieldValue”设置为“NA”
当我知道属性名称时,获取属性的列属性(名称)值的一种方法如下。
myUserModel.GetType().GetProperty("FirstName").GetCustomAttributes(typeof(System.Data.Linq.Mapping.ColumnAttribute), false).Cast<System.Data.Linq.Mapping.ColumnAttribute>().Single().Name
但就我而言,属性名称将不为人所知。我必须根据 myModel1Field.FieldAlias 值找到该属性。这件事该怎么办呢。请建议。
MyUserModel 及其其中一个属性
public class MyUserModel {
[Column(Name = "first_name", DbType = "varchar")]
public string FirstName { get; set; }
}
现在,如果 myModel1Field.FieldAlias 是“first_name”,那么我必须在 MyUserModel 中搜索 Column 属性(名称)作为 first_name 的属性。如果它存在,我必须将其值设置为“FieldValue”。否则将“FieldValue”设置为“NA”。
List<MyModel1> myModel1 = new List<MyModel1>();
MyUserModel myUserModel = new MyUserModel();
List<MyModel2> myModel2 = new List<MyModel1>();
myModel1 = m_Service1.GetMyModelFields();
myUserModel = m_Service2.GetMyUserDetails();
myModel2 = (from myModel1Field in myModel1
select new MyModel2 { FieldCaption = myModel1Field.FieldAlias,
FieldValue = "" }).ToList<MyModel2>();
myModel1Field.FieldAlias text will be same as value of one of the Column attribute of one of the property in myUserModel. So I have to search for the column atribute(Name) in myUserModel and get the corresponding property values and assign it to 'FieldValue'. If I can't find the value in myUserModel I can set 'FieldValue' as "NA"
One way to get the column attribute(Name) value of for a property is as below when I know the Property name.
myUserModel.GetType().GetProperty("FirstName").GetCustomAttributes(typeof(System.Data.Linq.Mapping.ColumnAttribute), false).Cast<System.Data.Linq.Mapping.ColumnAttribute>().Single().Name
But in my case Property name will not be known. I have to find the property based on the myModel1Field.FieldAlias value. How to go about this. Please suggest.
MyUserModel with one of it's properties
public class MyUserModel {
[Column(Name = "first_name", DbType = "varchar")]
public string FirstName { get; set; }
}
Now if myModel1Field.FieldAlias is 'first_name' then I have to search in MyUserModel for a property with Column attribute(Name) as first_name. If it exists i have to set it's value to 'FieldValue'. Else set 'FieldValue' as "NA".

如果您想获取某个属性的值,并且您只知道该属性的 ColumnAttribute 属性之一的 Name 属性,您可以执行以下操作:这
是您想要的吗?
If you want to get the value of a property and you only know the Name property of one of the ColumnAttribute attributes on it what you can do is this:
