vb.net get result of sql statement - vb.net

Question

Hello take a look at the code below:
Try
con.ConnectionString = strCon
Dim strCommand as String = "RESTORE FILELISTONLY
FROM DISK = 'C:\AdventureWorks.BAK'
WITH FILE = 1
GO"
Dim cm As New SqlClient.SqlCommand(strCommand, con)
con.Open()
cm.ExecuteNonQuery()
Does anyone know how to get the list of logical files for my database, it does not work with executereader. i want to get the mdf and ldf files name for my database backup file.
Thanks.

As I've said before - the GO is NOT a T-SQL keyword - drop that!
And secondly, you don't need a WITH FILE when restoring only the file headers - try this:
Dim strCommand as String = "RESTORE FILELISTONLY
FROM DISK = 'C:\AdventureWorks.BAK'"
This will return several pieces of data - so you need to deal with a result set and thus use .ExecuteReader() to get this data from the query.
Try this code (it's C#, but should be easy enough to convert to VB.NET):
using System;
using System.Data;
using System.Data.SqlClient;
namespace GetPhysicalDbNames
{
class Program
{
static void Main(string[] args)
{
string stmt = #"RESTORE FILELISTONLY FROM DISK = 'D:\temp\AW2012.BAK'";
using (SqlConnection conn = new SqlConnection("server=.;database=master;integrated Security=SSPI"))
using (SqlCommand cmd = new SqlCommand(stmt, conn))
{
DataTable tblInfo = new DataTable();
SqlDataAdapter dap = new SqlDataAdapter(cmd);
dap.Fill(tblInfo);
foreach (DataRow row in tblInfo.Rows)
{
Console.WriteLine("Logical name: {0}", row["LogicalName"]);
Console.WriteLine("Physical file name: {0}", row["PhysicalName"]);
}
}
}
}
}
Executing that RESTORE command returns a result set, which contains among other two columns LogicalName and PhysicalName (which is the actual, complete physical file name of the .mdf and .ldf files)
