C# error CS1061 4

Question

I'm trying to develop a simple ping pong game in Visual studio (C#). I'm getting this error in my code.

Severity Code Description Project File Line Suppression State
Error CS1061 'object' does not contain a definition for 'Top' and no accessible extension method 'Top' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) pingpong C:\Users\acer\Desktop\pingpong\Form1.cs 134 Active

Answer 1

Hello @maryam mohammad ,

The Visual Studio compiler gives a clear answer: the variable or parameter named "player" is defined as a type that does not have property name "Top".

Please check the type of your "player" and change the type. Maybe 'casting' could be helpful too.

Answer 2

The tag "small-basic" is for Technical questions about Microsoft Small Basic, the only text-based language and IDE built for students to learn to code

Please look for a more fitting tag as your question in not about Small Basic
e.g. "dotnet-csharp" or even "not-supported""
