How do I create a generic class in C#?

Can you explain how to create a generic class in C#?

Sure! In C#, you can create a generic class by using angle brackets. For example:

public class GenericClass<T> {
    private T data;

    public GenericClass(T data) {
        this.data = data;
    }

    public T GetData() {
        return data;
    }
}

What does the 'T' represent in the generic class?

The 'T' is a type parameter that acts as a placeholder for the data type you want to use. When you create an instance of the class, you specify the actual type.

Can I use multiple type parameters in a generic class?

Yes, you can! You just need to separate them with commas. For example:

public class GenericClass<T, U> {
    private T firstData;
    private U secondData;

    public GenericClass(T firstData, U secondData) {
        this.firstData = firstData;
        this.secondData = secondData;
    }
}

Are there any constraints I can apply to the type parameters?

Absolutely! You can use constraints to specify that a type parameter must be a reference type, value type, or implement a specific interface. For example:

public class GenericClass<T> where T : IDisposable {
    // Class implementation
}
