Как непосредственно использовать код при работе с БД в VS 2010?

using System.Data.SqlClient;

        SqlConnection conn;
        SqlDataAdapter adapter;
        SqlCommand command;
        string command1;
        string connStr;

               connStr = @"Data Source=tcp:xxx.xxx.xxx.xxx; // у тебя скорее локалхост какой-нить
                            Initial Catalog=xxxxxxxxxxxxxx;
                            Persist Security Info=true;
                            User ID=xxxxxxxxxx;
                            Password=xxxxxxxxxxxxxx";

                conn.Open(); // открыли соединение
                command1 = "SELECT * FROM `схема`.`таблица`"
                adapter = new SqlDataAdapter(command1, conn);
                adapter.Fill(ds1);
                dataGridView1.DataSource = ds1.Tables[0];
                conn.Close(); // закрыли соединение

                command1 = "CREATE TABLE [dbo].[Requests] ( [Id]  INT IDENTITY (1, 1) NOT NULL, [Name]        NVARCHAR (50)  NOT NULL, [Description] NVARCHAR (200) NULL, [Comment]     NVARCHAR (200) NULL [Status]      INT NOT NULL, [Priority]    INT NOT NULL, [ActivId]     INT NULL, [File]  NVARCHAR (200) NULL, [CategoryId]  INT NULL, [UserId]  INT NULL, [ExecutorId]  INT NULL, [LifecycleId] INT NOT NULL, PRIMARY KEY CLUSTERED ([Id] ASC), CONSTRAINT [FK_Requests_ToCategories] FOREIGN KEY ([CategoryId]) REFERENCES [dbo].[Categories] ([Id]) ON DELETE SET NULL, CONSTRAINT [FK_Requests_ToUsers] FOREIGN KEY ([UserId]) REFERENCES [dbo].[Users] ([Id]) ON DELETE SET NULL, CONSTRAINT [FK_Requests_ToLifecycles] FOREIGN KEY ([LifecycleId]) REFERENCES [dbo].[Lifecycles] ([Id]) ON DELETE CASCADE,CONSTRAINT [FK_Requests_ToActivs] FOREIGN KEY ([ActivId]) REFERENCES [dbo].[Activs] ([Id]) ON DELETE SET NULL);"
                command = new SqlCommand(command1, conn);
                command.ExecuteNonQuery();
