Is it good practice to use ToString() to convert a number directly to a string?

Question

Is it good practice to convert a number to a string directly using ToString()? Like this:

string numStr = 0.ToString();

Or should the number be entered into an int variable first and then use ToString() on that? Like this:

int num = 0;
string numStr = num.ToString();

Answer 1

Its a Good practice to store your numbers in a Variable and then using the ToString() See example at the end

ToString() accepts an over load like ToString(IFormatProvider provider) where you can specify culture-specific format information

Console.WriteLine(value.ToString(CultureInfo.InvariantCulture));

The Alternative to ToString() is to use Convert.ToString(Int value) the difference is that Convert also handles null values

var str = Convert.ToString(value);
var str1 = Convert.ToString(value,CultureInfo.InvariantCulture);

Is it good practice to convert a number to a string directly using ToString()? Like this:

Example

1.ToString(); // Compiles fine
-1.ToString(); // Compile error, note you can surround it with parenthesis to get it to compile
