As you can see from the code above, I have a custom object with 5 parameters and I want to be able to check for any one of them in the main class i.e.

if(SRvalues.Exists(x => x.SRprice == currentPriceValue))...
if(SRvalues.Exists(x => x.totalCount == totalVal))...
if(SRvalues.Exists(x => x.bullishCount == bullVal))...
if(SRvalues.Exists(x => x.bearishCount == bearVal))...
if(SRvalues.Exists(x => x.lineType == lineVal))...

but I am not sure how to go about coding for the Equals method so as to distinguish what parameter it is that I am checking for. Any help would be highly appreciated.
