C # Small methods PadLeft and PadRight

1. In C #, you can easily complement strings using PadLeft and PadRight.

PadLeft (int totalWidth, char paddingchar)//Paddingchar complement totalWidth length to the left of the string

PadRight (int totalWidth, char paddingchar)//Paddingchar complement totalWidth length to the right of the string

2.string.padleft (int length,char replacestr): If the string is less than length, it is filled with replacestr on the left side of the string.

Instance: string num=12 num. PadLeft (4, ' 0 '); The result is ' 0012 '//To see if the string length satisfies 4 bits and is not satisfied by "0" to the left of the string.
