compareTo/Equals

[Techno]

It's been a while since ive done this. Basically I have an object with properties which include:

ID (int)
name (string)


I want to be able to sort the collection based on the name. I have implemented and overriden CompareTo, Equals, GetHashCode and ToString however I have noticed that it shows me much less items in the collection than before overriding these. Any ideas where I am going wrong?


public int CompareTo(GenericListRecip other)
{
return this.name.CompareTo(other.name); //this method does not even get called!
}

public override string ToString()
{
return this.name;
}

public override int GetHashCode()
{
return this.id;
}

public override Equals(object obj)
{
if (obj is GenericListRecip)
{
return this.name == ((GenericListRecip)obj).name;
}
else
{
return false;
}
}




obviously if i take the implementation out - its all fine but doesnt sort it by the property/field I would like. Any ideas?

If you want to be able to sort a list of these objects then you should implement the IComparable interface. It is IComparable.Compare that is used when sorting.

Thanks, I did implement that but that didn't quite work however ive managed to make it work now - I had to call the Sort() method excplicitly...seems to work fine, calls the compareto method and works fine :-/
