Sql server 2008 SQL Server 2008-使用Scripter.EnumScript的脚本数据失败，返回“0”；用户“登录失败”；错误

我正在尝试为表的数据编写脚本

如果我使用windows身份验证（integratedsecurity=true），代码就会正常工作

如果我使用现有用户和密码切换到sql身份验证，它将无法尝试访问返回的可枚举脚本。用户是SQL登录名和管理员

代码的简化版本如下：

    //string connectionString = "Data Source=myserver; Initial Catalog=mydb; Integrated Security=True";            
    string connectionString = "Data Source=myserver; Initial Catalog=mydb; Integrated Security=False; User ID=user1; Password=1234;";

    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        connection.Open();

        ServerConnection serverConnection = new ServerConnection(connection);
        Server server = new Server(serverConnection);

        Database database = server.Databases["mydb"];
        Collection<SqlSmoObject> tables = new Collection<SqlSmoObject>();
        tables.Add(database.Tables["mytable"]);

        Scripter scripter = new Scripter(server);
        scripter.Options.ScriptData = true;
        scripter.Options.ScriptSchema = false;
        var scripts = scripter.EnumScript(tables.ToArray());

        Collection<string> coll = new Collection<string>();
        foreach (var item in scripts) // error is here
        {
            coll.Add(item);
        }
    }

更不经常的情况是：

System.Data.SqlClient.SqlException occurred
  Message=A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)
  Source=.Net SqlClient Data Provider
  ErrorCode=-2146232060
  Class=20
  LineNumber=0
  Number=233
  Server=myserver
  State=0
  StackTrace:
       at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection)
  InnerException: 

---

知道为什么会这样吗？

看起来像是一个脚本编写错误

Scripter可能使用原始连接的ConnectionString属性关闭现有连接并重新打开另一个连接。当然，如果安全信息没有持久化，则该连接字符串没有密码信息

因此，解决方法是使用安全信息创建连接：

string connectionString = "Data Source=myserver; Initial Catalog=mydb; Integrated Security=False; User ID=user1; Password=1234; Persist Security Info=True;";
// etc.

string connectionString = "Data Source=myserver; Initial Catalog=mydb; Integrated Security=False; User ID=user1; Password=1234; Persist Security Info=True;";
// etc.
