Andreas Ott

Hello togehter,

I need urgent a conversion from C++ to C#.

The code in C++ is below.

Can someone help me here.

Thanks a lot.

thanks, yes it is workling well.

Thanks and have a nice weekend.

Hello,

maybe a easy question.
What do you mean with this?

Console.ReadKey(true).KeyChar;

Error 1 Only assignment, call, increment, decrement, and new object
expressions can be used as a statement
C:\Sort_Wege\ShortWay_CSharp2\Program.cs 145 13 ShortWay_CSharp2

Why not so --> Console.ReadKey();

Greet Andreas
