Any reason to write the “private” keyword in C#?

阅读更多关于 Any reason to write the “private” keyword in C#?

问题 As far as I know, private is the default everywhere in C# (meaning that if I don't write public , protected , internal , etc. it will be private by default). (Please correct me if I am wrong.) So, what's the reason to write that keyword, or why does it even exist for members? For example, when an event handler is auto-generated it looks like this: private void RatTrap_MouseEnter(object sender, CheeseEventArgs e) { } But why does it even write private if that's implied and default? Just so

Maximum Method Name Length

阅读更多关于 Maximum Method Name Length

Does anyone happen to know what the maximum length of a method name is in your programming language of choice? I was going to make this a C# specific question, but I think it would be nice to know across the spectrum. What are the factors involved as well: Does the language specification limit this? What does the compiler limit it to? Is it different on 32bit vs 64bit machines? For C# I don't believe there's a specified hard limit. (Section 2.4.2 of the C# 5 spec doesn't give a limit, for example.) Roslyn v2.2.0.61624 seems to have a limit of 1024 characters; this is way beyond the bounds of

What exactly is the HTML5 <command> tag and what is the browser support

阅读更多关于 What exactly is the HTML5 tag and what is the browser support

问题 I've read the HTML5 spec for <command> and found the information on this element very vague. I've tried it out and found that it is not working in Chrome (latest version) and it is working on Safari (even older ones), sorry no FF (don't shoot me please) - Mac only test. I can't understand what is the use of this element or even if I'm using it correctly. I thank you in advance for any clarification about it! 回答1: It works on Firefox 3.6.13 from Windows by the way. The command element is meant

Java properties file specs [duplicate]

阅读更多关于 Java properties file specs [duplicate]

问题 Possible Duplicate: Escaping equal sign in properties files In a .properties file, can I use the character '=' after the first one? Like this: url=http://www.example.org/test= Is it allowed and where can I know that it is allowed if it indeed is? So far it seems to be working but I simply am not too sure it won't break later on. 回答1: You may put backslash escape character (\) before = and : . Or better use the following code that prints out how your property should be escaped : Properties

Constructor chaining in C++

阅读更多关于 Constructor chaining in C++

问题 My understanding of constructor chaining is that , when there are more than one constructors in a class (overloaded constructors) , if one of them tries to call another constructor,then this process is called CONSTRUCTOR CHAINING , which is not supported in C++ . Recently I came across this paragraph while reading online material.... It goes like this ... You may find yourself in the situation where you want to write a member function to re-initialize a class back to default values. Because

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago . I am writing some code to parse MP4 files ... Is there a free source to get documentation on the MP4 File Format Specification. So far I have only found an ISO document which I would need to purchase ISO PDF. Is MP4 Not an open standard ? 回答1: Here's the specification of the ISO base format, and here is the MP4

Are URIs case-insensitive?

阅读更多关于 Are URIs case-insensitive?

问题 When comparing two URIs to decide if they match or not, a client SHOULD use a case-sensitive octet-by-octet comparison of the entire URIs, with these exceptions: I read above Sentence in Http Rfc I think Url is case-insensitive but i dont undrestand what that means ? 回答1: In reality it depends on the web server. IIS is not case sensitive. Apache is. I suspect that the decision regarding IIS is rooted in the fact that the Windows file system is not case sensitive. IIS still meets that portion

Java: Rationale of the Object class not being declared abstract

阅读更多关于 Java: Rationale of the Object class not being declared abstract

问题 Why wasn't the java.lang.Object class declared to be abstract ? Surely for an Object to be useful it needs added state or behaviour, an Object class is an abstraction, and as such it should have been declared abstract ... why did they choose not to ? 回答1: Ande, I think you are approaching this -- pun NOT intended -- with an unnecessary degree of abstraction. I think this (IMHO) unnecessary level of abstraction is what is causing the "problem" here. You are perhaps approaching this from a

Max name length of variable or method in Java

阅读更多关于 Max name length of variable or method in Java

问题 Is there a max length for class/method/variable names in Java? the JLS doesn't seem to mention that. I know very long names are problematic anyway from code readability and maintainability perspective, but just out of curiosity is there a limitation (I guess class names might be limited by the file system maximal file name limitation). 回答1: If I'm not mistaken, the limit is not in the language itself but in the classfile format, which limits names to 64k, so for all practical intents and
