- 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?
- How do I make the return type of a method generic?
If you would want to return a value which is not type casteable to the generic type you pass, you might have to alter the code or make sure you pass a type that is casteable for the return value of method
- 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:
- Nullable type as a generic parameter possible? - Stack Overflow
The type 'int?' must be a non-nullable value type in order to use it as parameter 'T' in the generic type or method Is specifying a nullable type as a generic parameter at all possible?
- Creating a generic method in C# - Stack Overflow
I am trying to combine a bunch of similar methods into a generic method I have several methods that return the value of a querystring, or null if that querystring does not exist or is not in the
- 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
- Syntax and Sample Usage of _Generic in C11 - Stack Overflow
This is a pretty good introduction Here's the Overview: 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) Basically it works like a kind of switch, where the labels are type names which are tested against the type
