Use Convert.toString () as follows.
For example:
int a = 10;
string sa = convert . tostring(a);
The result of sa is "10".
Extension:
String to integer
If you are sure that a string is a character that can be converted into a number, you can use int. Parse(string s s), which returns the converted int value;
If you are not sure whether a string can be converted into a number, you can use int. Try parse (strings, out int result), which returns a bool value, indicating whether the conversion operation is successful or not. The parameter result is a variable that stores the conversion result.
