How to Read Url value.

Yesterday i m working on Url column of a list. My code has to read the Url value rather than Url.

and i wrote code simply like below.
foreach(Splistitem item in Allitems)
{
string urlvalue= item["Link"].tostring();
.......
}
as link is my column and item is splist item.

The above urlvalue is giving a url value which is converted to string.

to solve this i used SpFieldUrlValue.

SPFieldUrlValue linkField = new SPFieldUrlValue(item["Link"].tostring());
string linkname = linkField.Description;

Cheers i got the value finally.
