C# || How To Pad Center & Center Align A String Of Fixed Length Using C#

The following is a module with functions which demonstrates how to pad center and center align a string of a fixed length using C#.

The function demonstrated on this page center aligns the characters in a string by padding them on the left and right with a specified character, of a specified total length.

The returned string is padded with as many padding characters needed to reach a length of the specified total width.

The padding character is user defined, but if no padding character is specified, the string is padded using a whitespace (‘ ‘).


1. Pad Center

The example below demonstrates the use of ‘Utils.Extensions.PadCenter‘ to center align a string of a fixed length.

In this example, the default padding character is used to pad the string, which is a whitespace (‘ ‘).

C# || How To Generate Hourly Time Range With Minute Interval Using C#

The following is a module with functions which demonstrates how to generate an hourly time range with minute interval between a start and end time using C#.

The function demonstrated in this page generates a time value list containing the time from a starting hour to an ending hour, separated by a minute step. The starting and ending hour is an integer from 0 through 23 representing the 24 hour period of the day, and the minute step can be any minute interval, including decimal values.

The starting and ending hours can also be flipped, indicating that the results should be returned in descending order.

An optional parameter also exists which allows to tune the results. When the range is in ascending order, the parameter indicates that the results should exclude/include the entire ending hour. When the range is in descending order, the parameter indicates that the results should exclude/include the entire starting hour.
