What are type constraints in C#?
An example of an AI chatbot conversation about type constraints in C# programming.
What are type constraints in C#?
Type constraints in C# are rules that specify the types that can be used as arguments for a generic type parameter.
Can you give me an example of how to use type constraints?
Sure! You can use the where keyword to specify constraints. For example, where T : class restricts T to reference types.
What happens if I don't use type constraints?
If you don't use type constraints, the generic type can accept any type, which may lead to runtime errors if the expected type is not used.
Are there different types of constraints I can use?
Yes, you can use constraints like where T : struct for value types, where T : new() for types with a parameterless constructor, and more.
