Compiler Error CS0720 

Error Message

'static class': cannot declare indexers in a static class

Indexers are not meaningful in static classes, since they can only be used with instances, and it is not possible to create instances of a static type.


The following sample generates CS0720:

// CS0720.cs

public static class Test
    public int this[int index]  // CS0720
        get { return 1; }
        set {}

    static void Main() {}
