C#实体框架:关键字不支持：‘端口’
C#实体框架:关键字不支持：‘端口’

你好，我有多个项目连接到一个特定的DB，即CodeFirst实体框架。
除了一个顽固的项目外，所有项目都能成功地连接起来。
我得到的错误是：Keyword not supported: 'port'
我查看了无数的堆栈溢出问题、mysql论坛、实体框架论坛等，包括：
MappingException Edm.String与SqlServer.varbinary不兼容
我的连接字符串看起来像：server=myservername;port=3306;uid=myaccount;database=mydb;pwd=mypwd123
我的db.cs文件看起来如下：
public partial class MyDB : DbContext
{
public MyDB ()
: base("server=myservername;port=3306;uid=myaccount;database=mydb;pwd=mypwd123")
{
Logger.Trace("test123");
}
public virtual DbSet<MyItem> MyItems {
get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<MyItem>()
.Property(e => e.Content)
.IsUnicode(false);
}
}当我从连接字符串中删除port:3306时，我得到如下信息：
System.Data.Entity.Core.MappingException: Schema specified is not valid. Errors:

我和我的团队其他成员一样，都被这件事搞糊涂了。
