Question

I have written a class, for copying properties from one object to another, but I caught exception:
System.Reflection.TargetException: The object does not match the target type.
I checked, that fromPropValue is of correct type, is not null, etc.
Of course, property of recepient is Binary.

public class Reflector
{
    public void ReflectProperties(object from, object to) 
    { 
        Type toType = to.GetType();
        Type fromType = from.GetType();
        var toProperties = toType.GetProperties();

        foreach (var prop in toProperties)
        {
            var fromProp = fromType.GetProperty(prop.Name);

            if (fromProp != null)
            {
                var propType = prop.PropertyType;
                var fromPropValue = fromProp.GetValue(from, null);

                if (propType == typeof(Binary))
                    prop.SetValue(this, (Binary)fromPropValue, null); // <-- error
                else if (propType == typeof(string))
                    prop.SetValue(this, (string)fromPropValue, null);
                else if (propType == typeof(bool))
                    prop.SetValue(this, (bool)fromPropValue, null);
            }
        }
    }
}

P.S.: object from is parent of object to, and i want just to copy values of all properties from parent to child.

I think you want prop.SetValue(to, ... instead of prop.SetValue(this, ....

Also you don’t need the if statements and the casts. You can just do prop.SetValue(to, fromPropValue, null);
