Question: Import file to Maple

Hi everybody,

I have a follow problem:

Maple offers generate graph (network) for example in this way:

G:=Graph({{1,2},{1,3},{2,3}})

where  {{1,2},{1,3},{2,3}} is a list of edges.

In my study I need to generate a big graph (network), where list of edges is very long 
(contains more than 100000 edges).
Can I import from my directory (for example C:\\Desktop\) file, contains edges.
Now I copy from txt file all list of edges and paste into Maple. This way is very unproffesional,
moreover Maple hangs sometimes then.
I tried ImportData() and Tools -> Assistants -> Import Data but I can't import file correctly.

Please advise me:)

In my dreams it looks like:

list:=ImportData('C://Desktop/list.dat');
G:=Graph(list)

where list.dat looks like:

{1,2},{1,3},...,{99999,99987},{99999,100000}
