How to Load Data from Sql Sever 2014 to VS2008 Smart Device Application .sdf File?

Question

I have a project VS 2008 SmartDevice Application. There DBFile is created and my dbFile name is .DBFile.sdf with 3 tables. I need to update the table with values of another table in sql server 2014. I used XML File to load the table.

XML File Code : D:/Import.XML *

<?xml version='1.0'?>
<Items>
 <Item> 
    <CustCode>G0014</CustCode>
    <InDocketRef>030073</InDocketRef>   
    <ImportDate>2023-01-10T00:00:00</ImportDate>    
    <UniqueCode>8888</UniqueCode>
    <unit>CTN</unit>
  </Item>
  <Item>
    <CustCode>G0014</CustCode>
    <InDocketRef>030073</InDocketRef>   
    <ImportDate>2023-01-10T00:00:00</ImportDate>   
    <UniqueCode></UniqueCode>
    <unit></unit>
  </Item></Items>

in my .cs file i used the below code:

DataSet ds = new DataSet();
  ds.ReadXml(@"D:\Import.XML");
  DataTable table = new DataTable();
  table = ds.Tables[0];
  dataGrid1.DataSource = table;

but it throws the error:

Could not find a part of a path. But the path is correct.

Anyone please help to fix this issue? please suggest if there is any better way to connect with Sql server 2014 to retrieve the data.
