Hi All,
I am facing problem in copying content of table from a untyped dataset into
to a table inside the typed dataset. I wanted to copy the data into typed
dataset in order to ease the further processing using typed references.

DataSet ds = getDataFromDB(); - i am getting the dataset ds from a
webservice

I have got MyXSD which decsribes the shcema for the table which i am getting
from the webservice
and i am trying to cast like following
MyXSD myds = (MyXSD)ds; ==> but giving me invalid exception error

And i tried copying the table from ds into myds like
myds.Tables[0] = ds.Tables[0];

but it is giving me error saying myds.Tables[0] is READ ONLY....

I tried ImportRow also but getting errors and i don't want to manually go
thru the rows and put into my Typed dataset..

Thanks for your help.

Hi,

I believe (read that as I have not tried it!) that you can accomplish this
with the Merge member of the DataSet.

DataSet ds = getDataFromDB();
MyDataSet myds = new MyDataSet();

myds.Merge( ds );

For the cast to work your getDataFromDB() would have to actually be creating
a strongly typed dataset and merely return it as a generic DataSet.

Hope this helps
