So I have 2 string ,int Dictionaries named statsB and statsC.
I want to check if a string from StatsB is contained within statsC and if so compare the correlating integer of both.
I have no idea how to start

What I have tried:

foreach (var item in statsB)
          {
              if (statsC.ContainsKey(item))
              {


              }

          }

tried something like this but genuinely have no idea how to start

See example here: https://www.dotnetperls.com/dictionary-equals[^]

And here's another way: Compare two dictionaries using LINQ[^]

C#

foreach (string item in statsB.Keys)
{
   if (statsC.ContainsKey(item))
   {
      if (statsB[item] == statsC[item])
      {
         // values match
      }
      else
      {
         // values don't match
      }
   }
}

or

C#

foreach (var item in statsB)
{
   string key = item.Key;
   if (statsC.ContainsKey(key))
   {
      if (statsB[key] == statsC[key])
      {
         // values match
      }
      else
      {
         // values don't match
      }
   }
}

You should always refer to the documentation when you don't know how to use an object (assuming said object is documented).
Dictionary<TKey,TValue> Class[^]
KeyValuePair<TKey,TValue> Struct[^] (the type of item in the second solution)
This is also why using var for everything doesn't help beginners to clearly understand the code they write.
