How can I use a List<T> as a parameter on a method, I try this syntax :
void Export(List<T> data, params string[] parameters){ } I got compilation error:
The type or namespace name 'T' could not be found (are you missing a using directive or an assembly reference?)

Use the IsGenericType property to determine whether the type is generic, and use the IsGenericTypeDefinition property to determine whether the type is a generic type definition. Get an array that contains the generic type arguments, using the GetGenericArguments method.
To take a generic List<T> vs a bound List<int> you need to make the method generic as well. This is done by adding a generic parameter to the method much in the way you add it to a type. void Export<T>(List<T> data, params string[] parameters) { ... }
Its instances (only one per type exists) are used to represent classes and interfaces, therefore the T in Class<T> refers to the type of the class or interface that the current instance of Class represents.
In C#, the “T” parameter is often used to define functions that take any kind of type. They're used to write generic classes and methods that can work with any kind of data, while still maintaining strict type safety.

Try the following
void Export<T>(List<T> data, params string[] parameters) { ... } You need to make the method generic as well:
void Export<T>(List<T> data, params string[] parameters){ } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
