What are some examples of attributes in C#?

In C#, attributes are used to add metadata to classes, methods, and other entities. For example, the [Obsolete] attribute marks a method as outdated.

Can you give me more examples of commonly used attributes?

Sure! Other common attributes include [Serializable], which indicates that a class can be serialized, and [DataContract], used in WCF services.

How do I create a custom attribute?

To create a custom attribute, define a class that inherits from System.Attribute. You can then add properties to store data.

Can you show me a code example of a custom attribute?

Certainly! Here's a simple example:

[AttributeUsage(AttributeTargets.Class)]
public class MyCustomAttribute : Attribute {
    public string Description { get; }
    public MyCustomAttribute(string description) {
        Description = description;
    }
}
