I have the following code in C# Visual Studio 2010.

string connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\Database\\db.mde";
string sql = "SELECT * FROM Customer";
OleDbConnection connection = new OleDbConnection(connectionString);
OleDbDataAdapter adapter = new OleDbDataAdapter(sql, connection);

DataSet ds = new DataSet();
connection.Open();
adapter.Fill(ds, "Test Table");
connection.Close();
dataGridView1.DataSource = ds;
dataGridView1.DataMember = "Test Table";
ds.WriteXml("C:\\Users\\Desktop\\testfile.XML");

Now it does everything I want but I need to slightly modify the format of the XML file when it exports. Can this be easily done? I gather I need to provide a schema file which is fine but I’m not sure how to implement it with the dataset.

Currently the XML looks like this.

<?xml version="1.0" standalone="yes"?>
<NewDataSet>
  <Test_x0020_Table>
    <name>Customer1</name>
    <address>25 Big St</address>
    <suburb>Sydney NSW</suburb>
    <contact>Fred Nurk</contact>
    <phone>11 1111 1111</phone>
  </Test_x0020_Table>
</NewDataSet>

… but I want it to look like this

<?xml version="1.0" standalone="yes"?>
<Customers>
    <name>Customer1</name>
    <address>25 Big St</address>
    <suburb>Sydney NSW</suburb>
    <contact>Fred Nurk</contact>
    <phone>11 1111 1111</phone>
</Customers>

Any help would be greatly appreciated.

    The first node is the name of your table.

    You can change this by setting a name on your DataSet.

    DataSet ds = new DataSet(“Customers“); //plural

    The inner node is the record.

    You can change this by specifying the name when you fill the adapter.

    adapter.Fill(ds, “Customer“); //singular

    This will give you a result like:

     
<Customers>
  <Customer>
    <name>Customer1</name>
    <address>25 Big St</address>
    <suburb>Sydney NSW</suburb>
    <contact>Fred Nurk</contact>
    <phone>11 1111 1111</phone>
  </Customer>
</Customers>

    This means if you return multiple results you would end up with:

     
<Customers>
  <Customer>
    <name>Customer1</name>
    <address>25 Big St</address>
    <suburb>Sydney NSW</suburb>
    <contact>Fred Nurk</contact>
    <phone>11 1111 1111</phone>
  </Customer>
  <Customer>
    <name>Customer1</name>
    <address>25 Big St</address>
    <suburb>Sydney NSW</suburb>
    <contact>Fred Nurk</contact>
    <phone>11 1111 1111</phone>
  </Customer>
  <Customer>
    <name>Customer1</name>
    <address>25 Big St</address>
    <suburb>Sydney NSW</suburb>
    <contact>Fred Nurk</contact>
    <phone>11 1111 1111</phone>
  </Customer>
</Customers>

    You can’t have a single “Customer” because when you write the XML it’s formatting it as “Table” with “Records”.
