  • Hi,

    this is really great:
    local nValue as decimal
    nValue := 123.45m	
    Console.WriteLine( i"nValue: {nValue:######.0000}" ) // nValue: 123,4500
    Console.WriteLine( i"nValue {nValue:F6}" )  // nValue: 123,450000

    even if the .NET formatting strings are less powerful than the pictures we know from VO.

    P.S. I have also adjusted the wiki: docs.xsharp.it/doku.php?id=strings

  • Yes, Wolfgang, it's really convenient.

    I find the .net formatting strings is less useful for numbers than VO's when it comes to common numbers and amounts. The formatting in .net however covers a wider field (like hex-values). I think the date formatting in .net is easier with all the standard formats that are ready to use.

  • Hi Mathias,

    yes, I find the options for numeric less useful than the picture strings in VO. And after all, input of numerics is very important in any business application.

    But I see not why the picture clauses in the X# runtime could not be extended by the development team when we need that.

  • Hi,
    another question for this topic:
    I would like to use an interpolated string on a dictionary.
    Short example
    VAR dict := Dictionary<STRING, OBJECT>{}
    dict:Add("PL_ID", "0001")
    VAR val := ei"pl_id: {dict[\"pl_id\"]}"

    This throws three errors:
    error XS8076: Missing close delimiter '}' for interpolated expression started with '{'.
    error XS1056: Unexpected character '\'
    error XS1003: Syntax error, ']' expected

    Is this a bug or wrong syntax?

    Regards
    Stefan

  • Hi Stefan,

    Not sure if it should be considered a bug, but I think this is stretching interpolated strings a it too far! The point of using them is to make the code more readable, and this does not seem really readable to me :)

    I would instead use String.Format() for such complex embedding of values in strings:

    VAR val := System.String.Format("pl_id: {0}", dict["pl_id"])

    I realize this is not answering your question, but I thought it might be helpful to give this different suggestion.

  • Hi Chris,

    in C# it compiles without backslash.
    var dict = new Dictionary<String, Object>();
    dict.Add("PL_ID", "0001");
    var val = $"pl_id: {dict["PL_ID"]}";

    IntelliSense is a bit better than XIDE in this part. I think recognizing the brackets and change the color for the interpolated expression back to normal code color would help readability.
