我使用Entity Framework在我的数据库中执行存储过程(Azure SQL Server).
我的C#代码如下所示:
using (var context = new MyDataContext())
numberOfEffectedRows = context.MySPName(this.Id);
在大多数情况下(99.9%)执行,这很好.但是,有时它会因此错误而失败:
System.InvalidOperationException: Invalid operation. The connection is closed.

at ***.DoSomething() in ***
发生这种情况时:

有人知道为什么会这样,以及我怎么知道我的存储过程是否被执行?
最佳答案 连接已关闭是由于超时,因此建议您检查连接字符串中的连接超时
connectionString="Data Source=..;Initial Catalog=;Persist Security Info=..;User ID=..;Password=..;Connect Timeout=.."
对于诊断,我建议您运行SQL Server Profiler
