Formatting Strings in Visual Basic .NET
The value placeholder has the next format:
{ index [, alignment ][: format_string ] }
The index value gives the index numbered (zero based) of the parameter that should be inserted in that placeholder's position.
The alignment value is optional and it defines a minimum number of spaces the item should use.
If alignment is negative, the result is left-justified and if it's positive, the result is right-justified.
The format_string is also optional and indicates how the item will be formatted:
{ index [, alignment ][: format_string ] }
The index value gives the index numbered (zero based) of the parameter that should be inserted in that placeholder's position.
