Why it does not jump into if sentence? C# #UWP
<p>I have this HangMan game and i got problems. When user clicks on alphabet button, it wont jump into that if-sentence which i got in my code. "Current" variable is a string and the button content is a letter and i want to know if that guessing word contains that letter, which user clicks on. Even if i debug that code, i don't get the "current" variable(guessing word)in that Guessing method. Thanks for all!</p>
