Convert event from .net 1.1 to .net 2.0 or above

I decompiled a program built with .NET 1.1 and I need to rewrite in .NET 2.0 or above. I have difficulty understanding this code, and event is not my strong point. Visual Studio complains

"The event 'dataTransfering' can only appear on the hand side of += or -="

public delegate void DataTransferringDelegate(string name, long transBytes, long totalBytes);

public event DataTransferringDelegate dataTransferring
    {
        [MethodImpl(32)]
        add
        {
            this.dataTransferring = (FtpIO.DataTransferringDelegate)Delegate.Combine(this.dataTransferring, value);
        }
        [MethodImpl(32)]
        remove
        {
            this.dataTransferring = (FtpIO.DataTransferringDelegate)Delegate.Remove(this.dataTransferring, value);
        }
    }

public void upload(string fileName, bool resume)
{
    long length;
    long num2 = 0L;
    // some code removed here
    this.dataTransferring(fileName, num2, length);
}

So how to fix this code in .NET 2.0?

What you see is how compiler implements Event. You don't need those, compiler will create them automatically.

Revise your code and remove those details, like this:

public delegate void DataTransferringDelegate(string name, long transBytes, long totalBytes);

public event DataTransferringDelegate dataTransferring;

public void upload(string fileName, bool resume)
{
    long length;
    long num2 = 0L;
    // some code removed here
    dataTransferring(fileName, num2, length);
}
