例如:在强类型语言中，类型可以在编译时或运行时检查。在编译时，这意味着如果类型不兼容，编译器将报错。在运行时，意味着你可以很好地编译你的程序，但在运行时，它会抛出一个异常。

这里有一个非常简单的答案:

Runtime and compile time are programming terms that refer to different stages of software program development. In order to create a program, a developer first writes source code, which defines how the program will function. Small programs may only contain a few hundred lines of source code, while large programs may contain hundreds of thousands of lines of source code. The source code must be compiled into machine code in order to become and executable program. This compilation process is referred to as compile time.(think of a compiler as a translator)

用户可以打开并运行编译后的程序。当应用程序正在运行时，它被称为运行时。

术语“运行时”和“编译时”经常被程序员用来指代不同类型的错误。编译时错误是一种问题，例如语法错误或缺少文件引用，从而阻止程序成功编译。编译器产生编译时错误，并通常指出源代码的哪一行导致了问题。

如果一个程序的源代码已经被编译成一个可执行程序，那么它在程序运行时可能仍然有错误。例子包括不能工作的特性、意外的程序行为或程序崩溃。这些类型的问题被称为运行时错误，因为它们发生在运行时。

编译时和运行时之间的差异就是精明的理论家所说的阶段差异的一个例子。它是最难学习的概念之一，特别是对于没有太多编程语言背景的人来说。要解决这个问题，我发现问一下很有帮助

程序满足哪些不变量? 在这个阶段会出现什么问题? 如果阶段成功，后置条件是什么(我们知道什么)? 输入和输出是什么(如果有的话)?

编译时

The program need not satisfy any invariants. In fact, it needn't be a well-formed program at all. You could feed this HTML to the compiler and watch it barf... What can go wrong at compile time: Syntax errors Typechecking errors (Rarely) compiler crashes If the compiler succeeds, what do we know? The program was well formed---a meaningful program in whatever language. It's possible to start running the program. (The program might fail immediately, but at least we can try.) What are the inputs and outputs? Input was the program being compiled, plus any header files, interfaces, libraries, or other voodoo that it needed to import in order to get compiled. Output is hopefully assembly code or relocatable object code or even an executable program. Or if something goes wrong, output is a bunch of error messages.

运行时

We know nothing about the program's invariants---they are whatever the programmer put in. Run-time invariants are rarely enforced by the compiler alone; it needs help from the programmer. What can go wrong are run-time errors: Division by zero Dereferencing a null pointer Running out of memory Also there can be errors that are detected by the program itself: Trying to open a file that isn't there Trying find a web page and discovering that an alleged URL is not well formed If run-time succeeds, the program finishes (or keeps going) without crashing. Inputs and outputs are entirely up to the programmer. Files, windows on the screen, network packets, jobs sent to the printer, you name it. If the program launches missiles, that's an output, and it happens only at run time :-)

我认为它是错误的，以及什么时候可以发现错误。

编制时间:

string my_value = Console.ReadLine();
int i = my_value;

字符串值不能被赋给int类型的变量，因此编译器在编译时肯定知道这段代码有问题

运行时间:

string my_value = Console.ReadLine();
int i = int.Parse(my_value);

这里的结果取决于ReadLine()返回的字符串。有些值可以解析为int型，有些则不能。这只能在运行时确定

将源代码转换为“屏幕|磁盘|网络”可以(大致)以两种方式发生;称之为编译和解释。

在编译程序中(例如c和fortran):

源代码被输入到另一个程序(通常称为编译器)，该程序生成一个可执行程序(或一个错误)。 运行可执行文件(通过双击它，或在命令行上键入它的名称)

在第一步发生的事情被称为在“编译时”发生，在第二步发生的事情被称为在“运行时”发生。

在解释程序中(例如MicroSoft basic(在dos上)和python(我想)):

源代码被输入到另一个程序(通常称为解释器)，该程序直接“运行”它。在这里，解释器充当程序和操作系统(或非常简单的计算机中的硬件)之间的中间层。

在这种情况下，编译时和运行时之间的差异很难确定，而且与程序员或用户的关系也小得多。

Java是一种混合，代码被编译成字节码，然后在虚拟机上运行，虚拟机通常是字节码的解释器。

还有一种中间情况，即程序被编译为字节码并立即运行(如在awk或perl中)。

编译时间:您作为开发人员编译代码的时间段。

运行时间:用户运行你的软件的时间段。

你需要更明确的定义吗?
