static

问题 The following compiles fine, using static only during declaration of function: #include <stdio.h> static int a(); int a(){ return 5; } int main(){ printf("%d\n", a()); return 0; } As a side note, same behaviour as above happens with inline functions, i.e only the declaration could have the keyword. However the following fails, doing the same but on a variable: #include <stdio.h> static int a; int a = 5; int main(){ printf("%d\n", a); return 0; } Getting thew error: non-static declaration of

问题 I have recently run into some trouble while trying to perform the following logic: static const int size = getSize(); int getSize() { return 50; } The error I have received is initialiser element is not constant Having read online I understand that this issue is because the compiler evaluates the static const expression at compilation and therefore cannot know what the value is supposed to be. My question is how do I get around this? If I have a library that contains many functions but they

问题 Here's the simplified parts of code that I have: abstract class DataManager<TValue> { protected static Dictionary<string, TValue> Values; } and then I have: class TextManager : DataManager<string> { static TextManager() { Values = ... // Fill with data } } And, now I'm getting CA1810. I see a few solutions, like making Values public and setting them elsewhere, but I don't like that, or making a static method in TextManager to do the same thing, but is invoked when the program starts, but I

问题 I have the follwoing structure and object of structure defined in the header file as below: struct STConfigurationDetails { bool bAutoStart; bool bAutoLog; bool bAutoScan; bool bAutoMount; bool bAutoOpen; bool bAutoDetectLast; }; struct STConfigurationDetails g_objConfigurationDetails ; In the header file it self I have both method and method body which is using g_objConfigurationDetails . This works fine when I include the header file to another cpp file and call the method. But the moment I

问题 I need to use Dependency Injection in a static class. the method in the static class needs the value of an injected dependency. The following code sample demonstrates my problem: public static class XHelper { public static TResponse Execute(string metodo, TRequest request) { // How do I retrieve the IConfiguracion dependency here? IConfiguracion x = ...; // The dependency gives access to the value I need string y = x.apiUrl; return xxx; } } 回答1: You basically have two options: Change the
