Sorry for very silly question.
But, how can I input an integer from keyboard in C# Console
applications?
Like this, in C++ code:
"int i ; cin >i ;"
I just read some tutorials about C#, and I can get a "string" from
keyboard, but I can't get an integer.
Thank you in advance. 7 14880

int v = int.Parse(Conso le.ReadLine());
was at least one way.

You may get an exception if what you read is not a number

Yep.
The original poster should catch the exception and
so something appropriate if that happen.

For your information:
I found in a tutorial, a compact expression for Integer input:
int i = Convert.ToInt32 (Console.ReadLi ne());
Thank you again.
Best regards.

To quote from docs for Convert.ToInt32 :
Remarks
The return value is the result of invoking the Int32.Parse method on value.
