Delphi/Lazarus Pascal 中是否有等效于 C# 的字符串插值？ 我知道 Oxygene 有它支持 .Net 框架吗？

Question

Example of C# String Interpolation: To use interpolation in strings, put the name of the relevant variable between brackets {} and put a dollar sign $ in front of the string. This will tell C# to use interpolation.

double a = 3;
double b = 4;
Console.WriteLine($"Area of {a} and {b} is {0.5 * a * b}"); 

'''

Answer 1

No, there is nothing like C# string interpolation in Delphi or FreePascal. The closest equivalent is SysUtils.Format() , eg:

uses
  ..., SysUtils;

var
  a, b: Double;
begin
  a := 3.0;
  b := 4.0;
  WriteLn(Format('Area of %f and %f is %f', [a, b, 0.5 * a * b]));
  ...
end;
