c# - 如何以编程方式在Basic版本中创建sql数据库？在 Windows Azure 中

Question

其语法解释如下:

How to programatically create Sql Azure database of type Basic/Standard edition through Enity Framework code first

但是，我的代码是这样实现的:

 public static bool CreateDatabaseIfNotExists(string connectionString, string databaseName)
        {
            using (SqlConnection conn = new SqlConnection(connectionString))
            {
                conn.Open();

                SqlCommand cmd = new SqlCommand(
                    string.Format("SELECT * FROM sys.databases WHERE [name]=\'{0:S}\'", databaseName),
                    conn);

                cmd.CommandTimeout = int.MaxValue;

                if (cmd.ExecuteScalar() == null)
                {
                    SqlCommand cmd2 = new SqlCommand(
                        string.Format("CREATE DATABASE [{0:S}];", databaseName),
                        conn);
                    cmd2.CommandTimeout = int.MaxValue;

                    cmd2.ExecuteNonQuery();

                    return true;
                }
                else
                    return false;
            }
        }

我到底应该把基本字符串放在哪里，因为我不确定把它放在哪里。

您在数据库名称后指定版本:

SqlCommand cmd2 = new SqlCommand(string.Format("CREATE DATABASE [{0:S}] (SERVICE_OBJECTIVE = 'basic');", databaseName), conn);
