Private object syncHandle; Private object GetSyncHandle(){ InterLocked.CompareExchange(ref syncHandle, new object(), null); } 避免在临界区中调用未知代码 比如不要在临界区中使用事件,因为事件的处理方法由调用方注册,是未知的,会造成相关的问题,一定要保证临界区中方法的确定性 理解在WinForm和WPF中的跨...
ASSERT应放在函数入口处。 intFunction(objecta,objectb){ASSERT(a!=null);ASSERT(b!=null);...} 8. 尽量用乘法或其它方法代替除法,特别是浮点运算中的除法,但是要注意精度溢出的问题。整数乘除法在保证不溢出的情况下,先除后乘。 9. 保持单线程逻辑,除了调用异步I/O接口之外,不能使用多线程。 10.协程尽量...
例如:如果x如此被声明: class Test { // 任何引用类型对象都可以作为同步对象 object x = new object(); } 然后在进入Monitor.Wait前的代码: lock (x) Monitor.Wait (x); 下面的代码释放了被阻止的线程(稍后在另一个线程上执行): lock (x) Monitor.Pulse (x); 切换锁 为了完成工作,在等待的时候Monito...

HttpWebRequest request = null; if (url.StartsWith("https", StringComparison.OrdinalIgnoreCase)) { //对服务端证书进行有效性校验(非第三方权威机构颁发的证书,如自己生成的,不进行验证,这里返回true) ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(CheckValidationRes...
If the type is found in the compilation's assembly, that type is returned. Next, the core library (the library that defines System.Object and has no assembly references) is searched. If the type is found there, that type is returned. Finally, all remaining referenced non-extern assemblies...
[MessagePackObject] public class IntKeySample { [Key(3)] public int A { get; set; } [Key(10)] public int B { get; set; } } // [null,null,null,0,null,null,null,null,null,null,0] Console.WriteLine(MessagePackSerializer.SerializeToJson(new IntKeySample())); If you do not want...
MessagePack.Nilis the built-in type representing null/void in MessagePack for C#. Object Serialization MessagePack for C# can serialize your own publicclassorstructtypes. By default, serializable types must be annotated with the[MessagePackObject]attribute and members with the[Key]attribute. Keys can...
The following descriptions of strategies shows the decision making, what is realized in ifcSQL: (click on this line) Strategy no. 1:Store every IFC-File in a binary large object field. (-) no advantage over files (-) not searchable (-) no rule checking Strategy no. 2:Store every IFC...
There is no hard limit on line length. Use judgement to keep code easy to read and diff. See [F.3.1] ❌ AVOID Adding excessive complexity in compound statements.Indent dotted invocations one level deeper than the root object. Place the dot for each invocation at the beginning of that ...
