POD stands for Plain Old Data – that is, a class (whether defined with the keyword struct or the keyword class) without constructors, destructors and virtual members functions. Wikipedia’s article on POD goes into a bit more detail and defines it as: A Plain Old Data Structure in C++ is an aggregate class that contains … Read more
Since we all love one-liners … this one depends on the Newtonsoft NuGet package, which is popular and better than the default serializer. Newtonsoft.Json.JsonConvert.SerializeObject(new {foo = “bar”}) Documentation: Serializing and Deserializing JSON
Using extern is only of relevance when the program you’re building consists of multiple source files linked together, where some of the variables defined, for example, in source file file1.c need to be referenced in other source files, such as file2.c. It is important to understand the difference between defining a variable and declaring a … Read more
class A { public: int x; protected: int y; private: int z; }; class B : public A { // x is public // y is protected // z is not accessible from B }; class C : protected A { // x is protected // y is protected // z is not accessible from … Read more
Ian Mercer posted a similar solution as this on Phil Haack’s blog: foreach (var item in Model.Select((value, i) => new { i, value })) { var value = item.value; var index = item.i; } This gets you the item (item.value) and its index (item.i) by using this overload of LINQ’s Select: the second parameter of … Read more
The shortest way is by adding the ObsoleteAttribute as an attribute to the method. Make sure to include an appropriate explanation: [Obsolete(“Method1 is deprecated, please use Method2 instead.”)] public void Method1() { … } You can also cause the compilation to fail, treating the usage of the method as an error instead of warning, if … Read more
TL; DR run this in the Package Manager Console: Update-Package Microsoft.CodeDom.Providers.DotNetCompilerPlatform -r More information This problem is not related to Visual Studio itself, so answers suggesting adding build steps to copy files over are rather a workaround. Same with adding compiler binaries manually to the project. The Roslyn compiler comes from a NuGet package and … Read more
Yes, both will give you deferred execution. The difference is that IQueryable<T> is the interface that allows LINQ-to-SQL (LINQ.-to-anything really) to work. So if you further refine your query on an IQueryable<T>, that query will be executed in the database, if possible. For the IEnumerable<T> case, it will be LINQ-to-object, meaning that all objects matching … Read more
The differences between a class and a struct in C++ is: struct members and base classes/structs are public by default. class members and base classes/struts are private by default. Both classes and structs can have a mixture of public, protected and private members, can use inheritance and can have member functions. I would recommend you: … Read more
