In case you happen to have a generic method that returns a generic value but doesn't have generic parameters, you can use default(T) + (T)(object) cast, together with C# 8 pattern matching/type checks (as indicated in the other recent answers).
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?
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.
Generic is the opposite of specific. Generic and specific refer to the identification of a fact. Specific means a fact that has been specified. If you ask for (specify) a pain reliever, aspirin would be a specific pain reliever, while aspirin, acetaminophen, ibuprofen, and naproxen together would be generic pain relievers.
I have a generics class, Foo<T>. In a method of Foo, I want to get the class instance of type T, but I just can't call T.class. What is the preferred way to get around it using T.class?
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?
using LookupDictionary = System.Collections.Generic.Dictionary<string, int>; Now I want to accomplish the same with a generic type, while preserving it as a generic type:
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
The following is a snippet on how to make a java generic class to append a single item to an array. How can I make appendToArray a static method. Adding static to the method signature results in
In the following code, the t.Save () method call throws our friend the generic exception when the pixel height is 65501 for me. For reasons of curiosity, I repeated the test for width, and the same limit applied to saving.
