将数据库添加到现有SQL Server 2008

Question

I've spent a lot of time trying to research outside resources, but different solutions seem to be more involved than I was hoping.

I am trying to achieve the following:

• create simple database on existing SQL instance on this local computer.
• security should just be a simple user name and password
• other options are unnecessary (log, growth, max size, etc)

This is my first attempt at database integration with my program. using SQLite or SMO seemed slightly overwhelming to start. I've been trying to modify this sample code to work:

private void createDatabase()
{
    String str;
    SqlConnection myConn = new SqlConnection("Server=" + serverName + ";Integrated security=SSPI;database=master");

    str = "CREATE DATABASE " + dbName + " ON PRIMARY " +
           "(NAME = " + dbName + "_Data, " +
           "FILENAME = 'C:\\" + dbName + ".mdf', " +
           "SIZE = 2MB, MAXSIZE = 10MB, FILEGROWTH = 10%) " +
           "LOG ON (NAME = " + dbName + "_Log, " +
           "FILENAME = 'C:\\" + dbName + ".ldf', " +
           "SIZE = 1MB, " +
           "MAXSIZE = 5MB, " +
           "FILEGROWTH = 10%)";

    SqlCommand myCommand = new SqlCommand(str, myConn);
    try
    {
        myConn.Open();
        myCommand.ExecuteNonQuery();
        MessageBox.Show("DataBase is Created Successfully", "Success", MessageBoxButtons.OK, MessageBoxIcon.Information);
    }
    catch (System.Exception ex)
    {
        MessageBox.Show(ex.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Information);
    }
    finally
    {
        if (myConn.State == ConnectionState.Open)
        {
            myConn.Close();
        }
    }
}

Any ideas on how to create a simple query string or something to create a database? If there's a better way, that's fine but keep in mind I'm trying to keep it as simple as possible just to start with.

Using SMO:

    Server server = new Server("servername");
    Database db = new Database(server, "MyDatabaseName");
    db.Create();

To build an SMO application, you need to reference the SMO assemblies. Click 'Add Reference' and navigate to the folder

C:\Program Files\Microsoft SQL Server\100\SDK\Assemblies

Add references to these assemblies:

• Microsoft.SqlServer.ConnectionInfo.dll
• Microsoft.SqlServer.Smo.dll
• Microsoft.SqlServer.Management.Sdk.Sfc.dll
• Microsoft.SqlServer.SqlEnum.dll

Add this using statement to the file containing the above code:

using Microsoft.SqlServer.Management.Smo;
