我需要总数.如何用单个语句对结果求和?
我有这些陈述,他们的结果就在他们附近.
string a = "abc";
string b = "abc";
Console.Writeline(a == b); //true
object x = a;
object y = b;
Console.Writeline(x == y); // true
string c = new string(new char[] {'a','b','c'});
string d = new string(new char[] {'a','b','c'});
Console.Writeline(c == d); // true
object k = c;
object m = d;
Console.Writeline(k.Equals(m)) //true
Console.Writeline(k == m); // false

为什么最后的平等给我假?
问题是为什么(x == y)为真(k == m)为假

我正在尝试像任何其他隐藏文件的代码一样在 ashx 文件上展开和折叠方法和其他内容。当我这样做时tools > options > text editor and adding ashx as an extention of visual studio c#,一开始一切似乎都很好。我可以展开和折叠方法,还可以查看文件顶部的属性和方法。但后来我失去了大部分的智能。我无法访问我的用户定义的对象和方法。

I need to handle distributed transactions in a microservice architecture. In theory, one of the best ways of doing that is using the Saga Orchestration pattern. The problem is I could not find any detailed information about how to provide scalability.
Let's use the example below. There can be many CreateOrderSaga, if I have multiple OrderService.API and it will be the case. Because I can have more than one OrderService.API. Then if CreateOrderSaga is kind of a state machine, then …
