String Interpolation with format variable
(7 answers)
Closed 7 years ago.
Has anyone figured out how to reuse an interpolated string?
I.e. can anyone figure out how to do away with the string.Format in the following block of code?
foreach(var s in new[]{ "Primary_{0}_Home", "Secondary_{0}_Work" }){
sql = $"SELECT {string.format(s, "Street")}, {string.format(s, "City")} ..."
}
You can't do that.
Interpolated strings are set on compile time. You can't use string interpolation to load a string to format something not directly in the scope.
