Hi All,

Need to check if the propery of an object exits.

oMyObject.Message

In some cases the Message property may not exists. I know the GetType() can
do it.
How would you check it?

Thanks,

Joe
 
System.Reflection and iterate through the PropertyInfo[].

The Type of the object has a .GetProperties method.
 
Hi Robbin,

Thanks for your reply.

Here is the situation I have 2 objects such as: Execption or SMTPExecption
The SMTPExecption has the property StatusCode while the other does not.

I pass the the object into an error handle method where I log the properties into a text file.
Looking at the Watch window it seems that the Execption does not have System.Reflection etc...

Regards,

Joe

And when you performed an

Type myType = myException.GetType();

PropertyInfo[] properties = myType.GetProperties();

what did you get?
