我正在尝试获取包含在主对象中的列表中对象的值。
我有一个包含各种属性的主对象,这些属性可以是集合。
现在我正在努力找出如何访问包含在对象中的通用列表。
///<summary>
///Code for the inner class
///</summary>
public class TheClass
{
public TheClass();
string TheValue { get; set; }
} //Note this class is used for serialization so it won't compile as-is
///<summary>
///Code for the main class
///</summary>
public class MainClass
{
public MainClass();
public List<TheClass> TheList { get; set; }
public string SomeOtherProperty { get; set; }
public Class SomeOtherClass { get; set }
}
public List<MainClass> CompareTheValue(List<object> MyObjects, string ValueToCompare)
{
//I have the object deserialised as a list
var ObjectsToReturn = new List<MainClass>();
foreach(var mObject in MyObjects)
{
//Gets the properties
PropertyInfo piTheList = mObject.GetType().GetProperty("TheList");
object oTheList = piTheList.GetValue(MyObject, null);
//Now that I have the list object I extract the inner class
//and get the value of the property I want
PropertyInfo piTheValue = oTheList.PropertyType
.GetGenericArguments()[0]
.GetProperty("TheValue");
//get the TheValue out of the TheList and compare it for equality with
//ValueToCompare
//if it matches then add to a list to be returned
//Eventually I will write a Linq query to go through the list to do the comparison.
ObjectsToReturn.Add(objectsToReturn);
}
return ObjectsToReturn;
}
我尝试使用
SetValue()
来对MyObject进行操作,但出现错误(引述):
对象类型不符
private bool isCollection(PropertyInfo p)
{
try
{
var t = p.PropertyType.GetGenericTypeDefinition();
return typeof(Collection<>).IsAssignableFrom(t) ||
typeof(Collection).IsAssignableFrom(t);
}
catch
{
return false;
}
}
}
IList oTheList
