DiscardableAttribute Class

Marks a type definition as discardable.

Namespace: System.Runtime.CompilerServices
Assembly: mscorlib (in mscorlib.dll)

[ComVisibleAttribute(true)] 
public class DiscardableAttribute : Attribute
/** @attribute ComVisibleAttribute(true) */ 
public class DiscardableAttribute extends Attribute
ComVisibleAttribute(true) 
public class DiscardableAttribute extends Attribute

A type definition might be marked discardable if it is not referenced by any other code in its assembly. This might be useful for languages that support separate compilation, where it is only at link phase that it becomes known whether any type is actually referenced by other code.

The classes in System.Runtime.CompilerServices are for compiler writers' use only.

The following code example demonstrates how to apply the DiscardableAttribute attribute to a type.

using System;
using System.Runtime.CompilerServices;


[DiscardableAttribute()]
class Program
{
    
    static void Main(string[] args)
    {

        Console.WriteLine("The DiscardableAttribute attribute was applied.");

    }
}

System.Object
   System.Attribute
    System.Runtime.CompilerServices.DiscardableAttribute

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
