Hi, i am developing a game and this game saves scores in variables,the scoreboard is always visible on the form and keeps on updating each time a player wins, now i cant really figure out how i can display these scores. the code i developed gives a conversion error
what am i doing wrong here....

C#

int player = 0; //variable//
            if (cnt == 4)   //if this condition is met//
                player++;   //value of the variable should be incremented//
                textBox1.text = player;  //value of the variable should be displayed on the form//

code samples or alternatives would help

Another variation is:

C#

textBox1.text = player.ToString();

A slight difference in this version is that you can define the format for the number presentation. For example, you can define the format as:

C#

textBox1.text = player.ToString("#00");

And the result with number 4 would be "04".

Solution 1

You are directly assigning an integer value to a string.
This won't work until you type cast it into a string before assignment.

Try textBox1.text = Convert.ToString(player);

Just to clarify, this is conversion, not casting. A cast would be like textBox1.Text = (string)player, which wouldn't compile, because int can't be cast to string. By using Convert (above) or object.ToString() (below) a conversion method is being invoked to make a string from the value. It is also a good time to point out that it is good practice, whenever creating a new class, to implement (override) the ToString() method if an instance can logically be expressed as a string.

Using toString() directily is never a good idea when compared to Convert.ToString().

If the value was null accidentally, ToString() would throw an error.

I would disagree. In the case of reference types, like int above, using the structure's ToString() method is more readable, produces less IL code and will never result in a NullReferenceException. For String, you're unlikely to call ToString() so it's a non-issue; and for reference types that don't implement IConvertible you can't use Convert anyways.
