Question

I have a user control which deals with fileupload. I have defined a delegate as follows

public delegate void FileUploadSuccess<T>(T value,FileUploadType F)

value can be a string as well as byte array. FileUploadType is an enum which tells which type of file was uploaded.

Now I have declared a event in usercontrol to raise this.

public event FileUploadSuccess<string> successString;   //In case I want a file name

public event FileUploadSuccess<Byte[]> successStringImage;  // In case I want a byte[] of uploaded image

What I wanted was a generic event

public event FileUploadSuccess<T> successString. 

Answer 1

Except as part of generic types (i.e.

class Foo<T> { public event SomeEventType<T> SomeEventName; }

) there is no such thing as generic properties, fields, events, indexers or operators (only generic types and generic methods). Can the containing type here be generic?
