Question

我对将azure函数用于新的api Preview 2 .net核心感兴趣，因此我设置了一个小函数来查询数据库并向我返回结果。

public static class Function1
    {
        private readonly KPContext _context;
        private static SqlConnection connection = new SqlConnection();
        [FunctionName("Function1")]
        public static Object Run([HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)]HttpRequest req, TraceWriter log)
        {
            List<Employees> datastore = new List<Employees>();
            Employees employees = new Employees();
            string connstring = Environment.GetEnvironmentVariable("ConnectionStrings:SQlConnectionString");

            var conn = new SqlConnection(connstring);

            log.Info("C# HTTP trigger function processed a request.");

            conn.Open();

            var query = "select Employee_ID, Employee_LName, Employee_FName, CASE WHEN Username IS NULL THEN Employee_FName + '.' + Employee_LName ELSE Username end as Username from Employees";
            SqlCommand cmd = new SqlCommand(query, conn);
            SqlDataReader reader = cmd.ExecuteReader();

            while(reader.Read())
            {
                employees.Employee_ID = (int)reader[0];
                employees.Employee_LName = (string)reader[1] != null ? (string)reader[1] : "";
                employees.Employee_FName = (string)reader[2] != null ? (string)reader[2] : "";
                employees.UserName = (string)reader[3] != null ? (string)reader[3] : "";
                datastore.Add(employees);
            }
            return datastore;
        }
    }
}

所以这按预期工作，但最后只给我一个人作为所有结果，而不是给我每个单独的结果

因此，当我首先调试代码时，代码正在执行我希望遍历每一行的操作，然后将它们添加到我的数据存储中，然后突然间由于没有很好的解释，一条记录最终将其自身复制到了内部的其他所有记录上列表，即使它一直增加直到最后的数据存储计数，而且我有多次相同的记录，而不是我的所有员工。我从azure函数中提取了相同的确切代码，并放入了Web api .net core 2，它按预期运行。

在循环中创建一个新实例并将其插入。
