I tried my level best to write an improved version but failed.

inFiles.ToList().ForEach(i =>

               {

                   filePath = inFolder + "\\" + i.Value;

                   if (i.Key.Equals(replacementFile))

                   {

                       replacementCollection = GetReplacementDataFromFile(filePath);

                   }

                   else if (i.Key.Equals(standardizationFile))

                   {

                       standardizationCollection = GetStandardizationDataFromFile(filePath);

                   }                   
               });

The problem is that I cannot use a switch case over here because the comparison variables are not constant.

Kindly help to improve this code.

I am using C#(3.0).

Thanks
