<dbsystem>Postgres</dbsystem>
</defaultDatabase>
<database>
<host>localhost</host>
<port>5432</port>

我去，什么破代码模板，重新贴一次 

static void Main(string[] args)
{

XElement x = new XElement("DATABASES", new XAttribute("version", "1.1"),
new XElement("FTK", new XAttribute("version", "4.0"),
new XElement("defaultDatabase",
new XElement("host", "127.0.0.1"),
new XElement("port", "5432"),
new XElement("dbsystem", "Postgres")
),
new XElement("database",
new XElement("host", "127.0.0.1"),
new XElement("port", "5432"),
new XElement("dbsystem", "Postgres")
),
new XElement("database",
new XElement("host", "127.0.0.1"),
new XElement("port", "5432"),
new XElement("dbsystem", "Postgres")
)
)
);

Console.WriteLine(x.ToString());
Console.Read();
}
