How can I read the properties of an object that contains an element of array type using reflection in c#. If I have a method called GetMyProperties and I determine that the object is a custom type then how can I read the properties of an array and the values within. IsCustomType is method to determine if the type is custom type or not.
public void GetMyProperties(object obj)
{
foreach (PropertyInfo pinfo in obj.GetType().GetProperties())
{
if (!Helper.IsCustomType(pinfo.PropertyType))
{
string s = pinfo.GetValue(obj, null).ToString();
propArray.Add(s);
}
else
{
object o = pinfo.GetValue(obj, null);
GetMyProperties(o);
}
}
}
The scenario is, I have an object of ArrayClass and ArrayClass has two properties:
-string Id
-DeptArray[] depts
DeptArray is another class with 2 properties:
-string code
-string value
So, this methods gets an object of ArrayClass. I want to read all the properties to top-to-bottom and store name/value pair in a dictionary/list item. I am able to do it for value, custom, enum type. I got stuck with array of objects. Not sure how to do it.
Try this code:
public static void GetMyProperties(object obj)
{
foreach (PropertyInfo pinfo in obj.GetType().GetProperties())
{
var getMethod = pinfo.GetGetMethod();
if (getMethod.ReturnType.IsArray)
{
var arrayObject = getMethod.Invoke(obj, null);
foreach (object element in (Array) arrayObject)
{
foreach (PropertyInfo arrayObjPinfo in element.GetType().GetProperties())
{
Console.WriteLine(arrayObjPinfo.Name + ":" + arrayObjPinfo.GetGetMethod().Invoke(element, null).ToString());
}
}
}
}
}
I've tested this code and it resolves arrays through reflection correctly.
