SQLBulkcopy

Question

I have the same names as xml in database, have tried with different dbtypes as int, float, nvarchar etc.
sometimes it copy only the first 2 elements in the xmldocument. I got an error that says "The given ColumnName 'omgang' does not match up with any column
in data source". And sometimes the "omgang" column is copied but with wrong value. I also tried with ColumnMappings without success.
Im using VS 2010 Express C# with Framework 2.0, SqlServer 2008 R2, SSMS.

private void button1_Click(object sender, EventArgs e)

string connectionString = "Data Source=AK\\SQLEXPRESS;Initial Catalog=Test3;Integrated Security=True";
DataSet ds = new DataSet();
DataTable sourcedata = new DataTable();
ds.ReadXml(@"http://netken.se/test/id=1&omgang=3485.xml");
sourcedata = ds.Tables[0];

using (SqlConnection sqlconn = new SqlConnection(connectionString))
{
sqlconn.Open();
using (SqlBulkCopy bulkCopy = new SqlBulkCopy(sqlconn))
{

 
bulkCopy.DestinationTableName = "Tbl_Test3";
bulkCopy.WriteToServer(sourcedata);
}
}
