使用 IBM.EntityFrameworkCore 的 IBM Informix 连接问题

Question

我正在尝试使用官方 IBM Nuget 库 IBM.EntityFrameworkCore 6.0.300 连接到 IBM Informix 数据库。打开连接后出现错误：

Culture is not supported. (Parameter 'culture')
4096 (0x1000) is an invalid culture identifier.

我的 DbContext 类是：

public class AppDbContext : DbContext
{
    public AppDbContext() : base() { }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        optionsBuilder.UseDb2
        (@"Host=10.216.1.6:1526;Server=my_server;Database=my_database;userid=my_user;password=*******", p => p.SetServerInfo(IBMDBServerType.IDS));
    }

    public DbSet<Flyer> Flyers => Set<Flyer>();
}

有什么解决这个问题的建议吗？

编辑：

异常调用栈为：

   at System.Globalization.CultureInfo..ctor(Int32 culture, Boolean useUserOverride)
   at IBM.Data.Db2.ODC.InvalidArgument()
   at IBM.Data.Db2.DB2ConnPool.ReplaceConnectionStringParms(DB2Connection connection, String szValue, DB2ConnSettings& pSettings, DB2ConnSettingsInternal& pSettingsInternal, Boolean bAttach, Boolean pushDownStrAppended)
   at IBM.Data.Db2.DB2Connection.set_ConnectionString(String value)

编辑＃2：

我解决了与文化相关的问题：我简单地添加了 en_US 组合作为一种计算机语言并且它起作用了。之前我只安装了 fr_CH 和 en_CH 语言。

如评论所说，连接字符串错误。我改变了它，现在看起来像这样：

optionsBuilder.UseDb2(@"Server=10.216.1.6:1526;Database=my_database;user id=my_user;password=*******", p => {
                p.SetServerInfo(IBMDBServerType.IDS);
            });

但是还是不行，我得到一个新的错误：

ERROR [08001] [IBM] SQL30081N  A communication error has been detected. Communication protocol being used: "TCP/IP".  Communication API being used: "SOCKETS".  Location where the error was detected: "10.216.1.6".  Communication function detecting the error: "recv".  Protocol specific error code(s): "*", "*", "0".  SQLSTATE=08001

和堆栈跟踪：

我安装了 Informix SDK 4.50 并为我的数据库配置了一个新的 ODBC 数据源。我尝试使用库

IfxConnection

中的方法

Informix.Net.Core.dll

打开与数据库的连接。我可以使用此连接字符串成功连接到数据库：

@"Host=10.216.1.6:1526;Server=instance_name;Database=my_database;User ID=my_userid;Password=*******"

数据库版本是11.50，会不会跟DB版本有关？

我们在同一台机器上还有其他实例，这会影响数据库连接吗？
