当您知道C＃属性值的类名（不是属性名）时，设置它

Question

I have a class as follows:

  public class DummyReturnDto
  {
      public Set1ReturnDto Foo { get; set; }
      public Set2ReturnDto Bar { get; set; }

      public DummyReturnDto()
      {
          Set1 = new Set1ReturnDto();
          Set2 = new Set2ReturnDto();
      }
  }

where all the properties are guaranteed to have classes as their types and will be unique. I would like to use reflection to set the value for the property given a particular type. So for Set1ReturnDto :

var propertyInfo = obj.GetType().GetProperty(Set1ReturnDto, ??????);
propertyInfo.SetValue(obj, value, null);

and then for Set2ReturnDto

var propertyInfo = obj.GetType().GetProperty(Set2ReturnDto, ??????);
propertyInfo.SetValue(obj, value, null);

EDIT:

This is part of the needed knowledge to implement requirements for Generic approach to dealing with multiple result sets from EF stored procedure

Answer 1

This will do it:

var propertyInfo = typeof(DummyReturnDto).GetProperties()
                       .Single(p => p.PropertyType == typeof(Set1ReturnDto));
