C #, int to string, string to int

1, int to string
Use tostring
Or convert. tostring () is as follows:

For example:
Int varint = 1;
String varstring = convert. tostring (varint );
String varstring2 = varint. tostring ();

2. Convert string to int.
If it is determined that the character string can be converted to a number, Int. parse (string s) can be used. This statement returns the converted int value;
If you cannot determine whether the string can be converted to a number, you can use Int. tryparse (string S, out int result). The return value of this statement is bool, indicating whether the conversion operation is successful. The result parameter is a variable that stores the conversion result.

For example:
String STR = string. empty;
STR = "123 ";
Int result = int. parse (STR );

String STR = string. empty;
STR = "XYZ ";
Int result;
Int. tryparse (STR, out result );
