Question

i have this following code. It is not adding new key values to the dictionary….whats wrong??

while(true)
{
TimeSpan t = // some timespan which is updating every second
int value =  // some value associated with timespan

Dictionary<TimeSpan,int> _dict = new Dictionary<TimeSpan,int>();
_dict.Add(t,value);
}

Answer 1

The problem is that you are instantiating a brand new dictionary each time the loop executes

Try this:

Dictionary<TimeSpan,int> _dict = new Dictionary<TimeSpan,int>();
while(true)
{
       TimeSpan t = // some timespan which is updating every second
       int value =  // some value associated with timespan
       _dict.Add(t,value);
}

As a side note, it might make more sense to just use the total elapsed ticks or milliseconds as the key instead of a time-span object
