Question

I am currently writing a Lib to make use of a HttpWebRequest class and properties. After calling certain methods I will need my HttpWebRequest attribute of the class to be reconstructed, but not from scratch.

This is what I want to accomplish:

1. Backup the properties from the existing HttpWebRequest

   System.Reflection.PropertyInfo[] properties = m_HttpWebRequest.GetType ().GetProperties ();

2. Re-instantiate the attribute, creating a new WebRequest

   m_HttpWebRequest = (HttpWebRequest)WebRequest.Create(requestUrl);

3. Add the copied properties to the new instance. Which I am unable to do yet.

Any ideas of how to implement the third step?
Currently I can get the name of each Property by using:

properties[index].Name

But I can’t reference the value.

This should roughly get you there:

foreach(var prop in m_HttpWebRequest.GetType().GetProperties())
{
    if(!(prop.CanWrite && prop.CanRead))
        continue;

    var val = prop.GetValue(m_HttpWebRequest, BindingFlags.GetProperty, null, null, null);
    if (val == null)
        continue;

    prop.SetValue(m_HttpWebRequest2, val, BindingFlags.SetProperty, null, null, null);
}
