Question

我尝试连接的数据库位于AWS服务器上，我正在尝试编写一个C＃脚本，用于从数据库中提取数据。我能找到的唯一教程是使用localhost。这是我尝试过的一些代码：

static void Main()
{
    SqlConnection myConnection = new SqlConnection(
                                   "user id=MyUsername;" +
                                   "password=MyPassword;" + 
                                   "server=MyServerName.ctf1qojvktpk.us-west-2.rds.amazonaws.com:3306;" +
                                   "Trusted_Connection=yes;" +
                                   "database=MyDBName; " +
                                   "connection timeout=30");

    try
    {
        myConnection.Open();
    }
    catch (Exception e)
    {
        Console.WriteLine(e.ToString());
    }
}

看起来它是一个mySql数据库。您需要安装MySQL Connector for .NET。

示例connectionstring

<add name="MyConnection" connectionString="server=myamazonserver.eu-central-1.rds.amazonaws.com;user id=rootusername;password=mypassword;database=mydatabasename; Convert Zero DateTime=True; Allow User Variables=True" providerName="MySql.Data.MySqlClient" />

或以普通代码

static void Main()
{
    SqlConnection myConnection = 
       new SqlConnection(
            "server=myamazonserver.eu-central-1.rds.amazonaws.com;user id=rootusername;password=mypassword;database=mydatabasename; Convert Zero DateTime=True; Allow User Variables=True" providerName="MySql.Data.MySqlClient"
          );
    try
    {
        myConnection.Open();
    }
    catch (Exception e)
    {
        Console.WriteLine(e.ToString());
    }

}

如何连接到不在localhost上的SQL Server数据库服务器？
