- How can I pass in a func with a generic type parameter?
You can certainly define generic delegates, after all, that's exactly what Func and Action are They are treated as generic definitions, just like generic interfaces and classes are However, you cannot use generic definitions in method signatures, only parameterized generic types Quite simply you cannot do what you are trying to achieve with a delegate alone
- c# - How to compare values of generic types? - Stack Overflow
So, two questions: Why do we observe this weird behaviour? What keeps us from comparing the values of generic types which are known to be IComparable? Doesn't it somehow defeat the entire purpose of generic constraints? How do I resolve this, or at least work around it?
- Can I make a generic optional, defaulting to a certain class?
My question is related to Is there a reasonable approach to quot;default quot; type parameters in C# Generics?, but using an inner generic class that approach doesn't work Given code like this:
- How do you provide a default type for generics? - Stack Overflow
The generic parameter type will be the same for all methods, so I would like it at the class level I know I could make a generic version and then inherit from it for the int version, but I was just hoping to get it all in one but I didn't know of any way to do that
- java - How to Map to Generic Type? - Stack Overflow
Mapstruct is a code generator So it needs to know which types to construct in order to generate a method implementation Having said that, you could do this smarter by using a base mapping method on which you define all the @Mapping annotations and ignore the generic type mapping You still have the methods above but you just specify @InheritConfiguration Alternatively you could consider
- C# Generics and Type Checking - Stack Overflow
A great example of when this would be useful is generic serialization with wildly varying types If the object being passed in is a string, why do the extra work?
- Syntax and Sample Usage of _Generic in C11 - Stack Overflow
Generic selection is implemented with a new keyword: _Generic The syntax is similar to a simple switch statement for types: _Generic( 'a', char: 1, int: 2, long: 3, default: 0) evaluates to 2 (character constants are ints in C)
- Using List lt;T gt; in C# (Generics) - Stack Overflow
That's not how generics work MyMethod(List<T> list) is an invalid method signature (unless your class is a generic class with a Type Parameter T)
