请参阅编译时间和运行时间之间的差异...引用类型&值类型 [英] please what is defference between compile time and run time...reference type & value type

问题描述

大家好，我是初学者
请在编译时间和运行时间之间有何不同...引用类型和值类型，如果可能的话，请简单说明.

Hii everyone,i''m beginner
please what is defference between compile time and run time...reference type & value type in easy explain if its possible.

推荐答案

初学者的最佳去处C#是要读一本书并编写大量代码.该链接可能有助于一般理解C#和值类型以及引用类型和类型的基础: C#类型参考 [ ^ ]

编译时间:当您在Visual Studio IDE中编写代码时(在这种情况下)，当您尝试运行该程序时收到错误消息，或者在编写错误的代码时出现一小段混乱的行，即C#编译器在后台检查错误，因此甚至可以在运行代码之前进行修复.

运行时间:代码已编译并正在执行指令时程序的运行状态.

希望这个非常基本的解释可以帮助您开始.

欢呼

The best place for beginners to learn about C# is to read a book and write lots of code. This link might help to understand the basics of C# and value types and ref types and types in general: C# Types Reference[^]

Compile time: when you are writing code in the Visual Studio IDE (in this case) and you get an error when you try to run the program or you get a squiggly little line when you write wrong code, that''s the C# compiler in the background that''s checking for errors so you can fix it even before running your code.

Run time: the running state of your program when the code has been compiled and is executing instructions.

Hope this very basic explanation helps you kick-off.

Cheers

编译时间"是指构建代码时-编译器将源代码转换为IL时.

运行时"是执行代码的时间-对于ASP.NET，是在发出页面请求时执行的. (我个人更喜欢用执行时间"一词来区分它和公共语言运行时(CLR)"(又名虚拟机).)


有关编译时间与运行时的更多说明，请参见此内容.

关于值与引用类型的关系:
值类型:它将保存实际值. int，bool，float是值类型
引用类型:它将地址保存为值.字符串，对象是引用类型.


要了解有关值vs引用的更多信息，您应该了解堆栈和堆以及如何保存数据.

"Compile time" is when you build your code - when the compiler converts your source code into IL.

"Runtime" is when your code is executed - for ASP.NET, when a page request is made. (Personally I prefer the term "execution time" to distinguish between that and "the Common Language Runtime (CLR)" - aka the virtual machine.)


see this for more explanation about compile time vs runtime.

http://stackoverflow.com/questions/846103/runtime-vs-compile-time[^]

And about value vs reference type:
Value type : It will hold the actual values. int, bool, float are value types
Reference type: it will hold the address to the values. string, objects are reference type.


To know more about value vs ref, you should know stack and heap and how data are saved.
