Compiler Warning (level 3) CS0067

The event 'event' is never used

An event was declared but never used in the class in which it was declared.

The following sample generates CS0067:

// CS0067.cs
// compile with: /W:3
using System;
delegate void MyDelegate();

class MyClass
   public event MyDelegate evt;   // CS0067
   // uncomment TestMethod to resolve this CS0067
   private void TestMethod()
      if (evt != null)
   public static void Main()
