Check for the existance of a specific table in a dataset.

[UJ]

I'm getting a dataset back from a web service and I want to verify that the
table I want exists before trying to access it (which will cause an
exception.) Is there an easy way to check for a specific table in my dataset
without doing a try/catch or is that the easiest way?

TIA - Jeff.

Hi,

if ( dataSet.Tables["MyTable"] == null )
throw new exception("Table no present");

in other words, just check for null when you refer to the table, the same
apply to columns

You can do what Ignacio says or there is also a "Contains" attribute
from the table and column collections to verify the existence of a
member before accessing it.
