========================================================== ====================

Tostring ("X2") is the string format controller in C #

X is hexadecimal
2. It indicates that each request is a double digit.

For example, 0x0a. If there is no 2, only 0xa is output.
Assume that there are two numbers 10 and 26. Normally, the hexadecimal format displays 0xa and 0x1a, which looks untidy. To look good, you can specify "X2". The displayed result is: 0x0a, 0x1a.
