Assign schema to already populated datatable

[Adam]

Hi, is it possible to associate a schema with an already populated
datatable?

I have a untyped datatable being returned from an external method.

I tried to use the DataTable.ReadXmlSchema method but it does not
work.

Thanks
Adam

It is not clear what you want. If you are receiving a populated
DataTable, then it already HAS a schema. Unless you are referring to
something different. By "schema" we usually mean a list of columns with
their types. If the DataTable is populated, then it must already have
columns, and they must each have a type.

I think you have a problem understanding the concept, a datatable
(also a dataset) does not have an explicit schema, what they have are
a collection of columns (tables for dataset) and also relationship
among them. This is what is considered the schema.

In other words a datatable ALWAYS have a schema, if you want to change
the schema you have to change the columns and/or the constrains of the
table
