Editor to share with you what the output format of the Console.WriteLine () function in C# is. I hope you will get something after reading this article. Let's discuss it together.
Console.WriteLine () refers to the output to the screen, which is often used in console programs, and the output is one line. The next output is displayed on the next line.
Detailed explanation of the output format of Console.WriteLine () function in C #
Format items are in the following form:
{index [, alignment] [: formatString]}
Where "index" refers to the index placeholder, which must be known.
"alignment" literally means alignment, marked with ","
": formatString" is the qualification of the output format, marked with ":".
Alignment: optional, is a signed integer indicating the preferred format field width. If the align value is less than the length of the formatted string, align is ignored and the length of the formatted string is used as the field width. If align is positive, the formatted data for the field is right-aligned; if align is negative, the formatted data for the field is left-aligned. If you need to fill it, use white space. If you specify align, you need to use a comma.
FormatString: consists of standard or custom format specifiers.
