My problem is that my DataReceived event isn't being thrown. I have my ReceivedBytesThreshold set to 1 and i still ...Show All

  Hello Friends, I just want to know how to find plural of a word in C# I have one textbox where user will enter his word i.e Text. Then how to find the plural of that word.
