How can I create an xsd file out of a Dataset class file?

[Babu Mannaravalappil]

Hi all,

I apologize for posting this question on two groups. I did not know
which one out of "XML" and "ADONET" groups, should I post this.

I would like to create an xsd file out of an existing dataset.cs file
that can be visually manipulated in the VS.NET Dataset Designer wizard
in VS.NET 2003 with .NET 1.1 and C#.

Here is the issue in more detail:

Using the wizard I can drag and drop tables on to the dataset designer
suface, set relations between tables etc. Now, this wizard generates
a typed DataSet class for me which is remarkable and beautiful. I
love Visual Studio. But here is my problem. I would like to cusomize
some of the characteristics of my dataset via editing the ".cs" file
that the wizard created for me. But if and when I modify anything in
the xsd designer surface, that overwrites the class file.

Is there a way that I can use the class file as a starting point and
reverse engineer to create an xsd file that I can just double click
and open in the dataset designer? That way, I think I can keep my
modifications to the class file and still have the visual designer
feature for my class.

How can I do it? Or can I do it at all?

Babu.

Assuming that you have already created and filled a DataSet "ds" somewhere
in your program, issue this command after that:

ds.WriteXmlSchema("Filename")

Then, bring "filename".xsd into the project, and you can use it as needed.
