Need to check if the propery of an object exits.

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?
