Generic Classes: You can create a generic class by using angle brackets <T>, where T is a type parameter representing the data type that the class will work with. Here's an example of a generic class:
public class GenericClass<T>
{
private T data;
public GenericClass(T data)
{
this.data = data;
}
public T GetData()
{
return data;
}
}
You can use this generic class with different types:
GenericClass<int> intGeneric = new GenericClass<int>(42);
GenericClass<string> stringGeneric = new GenericClass<string>("Hello, World!");
int intValue = intGeneric.GetData();
string stringValue = stringGeneric.GetData();
2. Generic Methods: Similar to generic classes, you can define generic methods that accept type parameters. Here's an example:
public T GenericMethod<T>(T input)
{
return input;
}
You can call this method with various data types:
int intResult = GenericMethod(42);
string stringResult = GenericMethod("Hello, World!");
3. Constraints: You can add constraints to type parameters to restrict the types that can be used with a generic class or method. For example, you can specify that a type parameter must implement a specific interface or have a default constructor.
public class GenericClass<T> where T : IComparable
{
// This class can only work with types that implement IComparable.
}
