azure函数时间触发器和azure sql数据库之间的连接（带有c#）：错误。如何修复它

我将尝试使用C#将azure函数与azure数据库sql连接，但我不知道如何修复此错误。你有什么想法吗

错误： 我确实试着捕捉到了异常

这是一个代码：

using System;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Host;
using Microsoft.Extensions.Logging;
using System.Data.SqlClient;
using System.Threading.Tasks;
using Microsoft.Azure.Functions.Extensions;


namespace azuretosharepoint
{
    public static class Function1
    {
        [FunctionName("Function1")]
        public static async Task RunAsync([TimerTrigger("0 */1 * * * *")]TimerInfo myTimer, ILogger log)
        {
            try
            {
                // Get the connection string from app settings and use it to create a connection.
                var str = Environment.GetEnvironmentVariable("sqldb-connection");
                using (SqlConnection conn = new SqlConnection(str))
                {
                    conn.Open();
                    var text = "SELECT * FROM PERSONNE ;";
                    using (SqlCommand cmd = new SqlCommand(text, conn))
                    {
                    // Execute the command and log the # rows affected.
                    var rows = await cmd.ExecuteNonQueryAsync();
                    log.LogInformation($"{rows} rows were updated");
                    }
                }
            }
            catch(Exception e)
            {
                Console.WriteLine("{0} Exception caught.", e);
            }

        }
    }
}

如果您是这项服务的新手，您可以遵循这一点

检查代码后，没有任何错误。问题一定是连接问题。请检查您是否修改了连接字符串中的密码。

另一件事是确保为ip地址设置服务器防火墙规则。

错误很明显。凭证是错误的。完整异常很可能包含更多信息。在任何情况下，名为

sqladmin

的帐户听起来都不像任何服务都应该使用的帐户。请发布完整的异常文本，而不仅仅是消息。完整异常文本包含任何内部异常和堆栈跟踪，以及导致此错误的调用。发布连接字符串（无敏感信息）将有助于toonon，凭据是正确的，因为我能够连接azure data studio，但我将向您显示异常：生成的异常：System.Private.CoreLib中的“System.data.SqlClient.SqlException”。dll@PanagiotisKanavos我已经修改了帖子并放置了完整的eception帖子包含Stacktrace，但没有异常详细信息。
