How to get current property name via reflection?

Question

I would like to get property name when I\'m in it via reflection mechanism. Is it possible?

Update: I have code like this:

    public CarType Car

FWIW I implemented a system like this:

    [CrmAttribute("firstname")]
    public string FirstName
    {
       get { return GetPropValue(MethodBase.GetCurrentMethod().Name); }
       set { SetPropValue(MethodBase.GetCurrentMethod().Name, value); }
    }

    // this is in a base class, skipped that bit for clairty
    public T GetPropValue(string propName)
    {
        propName = propName.Replace("get_", "").Replace("set_", "");
        string attributeName = GetCrmAttributeName(propName);
        return GetAttributeValue(attributeName);            
    }

    public void SetPropValue(string propName, object value)
    {
        propName = propName.Replace("get_", "").Replace("set_", "");
        string attributeName = GetCrmAttributeName(propName);
        SetAttributeValue(attributeName, value);
    }

    private static Dictionary PropToAttributeMap = new Dictionary();
    private string GetCrmAttributeName(string propertyName)
    {
         // keyName for our propertyName to (static) CrmAttributeName cache
         string keyName = this.GetType().Name + propertyName;
         // have we already done this mapping?
         if (!PropToAttributeMap.ContainsKey(keyName))
         {
             Type t = this.GetType();
             PropertyInfo info = t.GetProperty(propertyName);
             if (info == null)
             {
                 throw new Exception("Cannot find a propety called " + propertyName);
             }

             object[] attrs = info.GetCustomAttributes(false);
             foreach (object o in attrs)
             {
                 CrmAttributeAttribute attr = o as CrmAttributeAttribute ;
                 if (attr != null)
                 {
                     // found it. Save the mapping for next time.
                     PropToAttributeMap[keyName] = attr.AttributeName;
                     return attr.AttributeName;
                 }
              }
              throw new Exception("Missing MemberOf attribute for " + info.Name + "." + propertyName + ". Could not auto-access value");
           }

           // return the existing mapping
           string result = PropToAttributeMap[keyName];
           return result;
        }

There's also a custom attribute class called CrmAttributeAttribute.

I'd strongly recommend against using GetStackFrame() as part of your solution, my original version of the solution was originally the much neater:

return GetPropValue();

But it was 600x slower than the version above.
