You can escape the %
character:
[DisplayFormat(DataFormatString = @"{0:#\%}")]
Note that there are two ways to use
as an escape character: if you prefix a string literal with the verbatim symbol (@
), then
characters are included in the string as-is, which means that as part of a format string a single
will function as an escape character.
Without the @
verbatim symbol,
s are interpreted as escape strings by the compiler and as such need to be escaped themselves, as \
.
Pick one or the other, but not both:
@"{0:#\%}" -> right
"{0:#\%}" -> right
@"{0:#\%}" -> wrong
