コードが関数から文字列を戻していない

Question

次の問題があります。関数の内部で使用できる定義済みの文字列がgameNameに含まれているかどうかを確認したいが、何とかそれらを戻しません。彼らは関数で宣言されているので、なぜ私は本当に理由を知らないし、主要部分に戻って輸送する必要があります。ところで、OpenFileDialog1のための入力が指定されたファイルです：HL1-SP-無限shift.7z

    } 


} 

}関数を呼び出すとき

Answer 1

、あなたが実際に設定していないが値を何かに戻す。試してみてください

string gamename = "If you see this in Debug you failed.\n Y U NO MAKE WORKING CODE?"; 
gamename = CheckGame(sourceName, gamename); 
lblconsole.Text = gamename; 

ここでは、さまざまな最適化を行うことができます。一つは、のように見えるためにあなたのif sおよびreturn Sを変更されている：コーディング

if (sourceName.Contains(hl1)) 
     return = hl1;
