Subsonic 3 - 更新 NullReferenceException [英] Subsonic 3 - Update NullReferenceException

问题描述

我将 Subsonic v3.0.0.3 与 Linq 模板一起使用.我正在尝试使用以下内容更新 SQL Server Express 数据库中的记录:

I am using Subsonic v3.0.0.3 with the Linq templates. I am attempting to update a record in a SQL Server Express database with the following:

var db = new MyDB(Constants.Database);
db.Update<Contact>()
  .Set(d => d.FirstName == contact.FirstName)
  .Where(d => d.Id == contact.Id)
  .Execute();

执行此行时，我收到 NullReferenceException.堆栈跟踪如下:

I am receiving a NullReferenceException when this line is executed. The stack trace is as follows:

   at SubSonic.Query.Update.GetCommand()
   at SubSonic.Query.Update.Execute()

有人可以提出问题所在吗?

Any chance that someone may be able to suggest what the problem is?

推荐答案

嗯 - 我会说确保连接字符串存在(我将在接下来的几周内修复丢失连接字符串的错误消息)，而不是那 - 这看起来像一个问题 - 你介意在 Github 上发帖吗?

Hmm - I would say to make sure the connection string is present (I'll be fixing the error message for missing connection strings in the coming weeks) other than that - this looks like an issue - would you mind posting at Github?
