ERROR Convert string to integer to store in IntPtr How to print from a DataGrind the current cell in which I am standing

score 2 · Answer 1

You have two syntax problems; the first of them and the one that you frame in the question:

if (m2 >=0 && m2 < 10 && n2 >= 0 && n2 < 10 && valores [m][n] ??)

The logical operators work on boolean values, in valores [m][n] you are returning an integer, you must compare it with something. The other error you have is in the do while in ponerMinas , the stop condition of the cycle while (valores[m][n] ! = 0) , the comparator != should not take spaces between them, leaving:

while (valores[m][n] != 0)

At the end of your if you put values [m] [n] which is an integer, not a boolean, that's why it's your error.

It was stated:

private int valores [][];
valores = new int [10] [10];

Which is an array of integers, so in your code you put the following at the end of the

if (m2 >=0 
    && m2 < 10 
    && n2 >= 0 
    && n2 < 10
    && valores [m][n]){// aquí está tu error valores como explicó arriba es un entero no un booleano
    //Logica
}
