.Net Core Strings.Asc/Mid/Chr/Len missing even after importing Microsoft.VisualBasic


.Net Core Strings.Asc/Mid/Chr/Len missing even after importing Microsoft.VisualBasic

will help you The Visual Basic Runtime will be shipped with .NET core 3, so those functions will work then.
You can verify this by trying it in preview SDK: the following worked as expected for me (using Microsoft.VisualBasic 10.3.0 package on Nuget)
code :
using static Microsoft.VisualBasic.Strings;

class Program { 
   static void Main() { 
      Asc("Apple");
      Mid("Apple", 2, 3);
      Chr(100);
      Len("Apple");
   }
}

Application crashes on startup - missing Microsoft.VisualBasic.PowerPacks

wish of those help It isn't that clear why PowerPacks is missing, the .NET 4 Client Profile could be an issue. There have been multiple versions of PowerPacks around and the version numbering got to be a mess. On my machine, that same version is reported as v2.0.50727, even though it is stored in the GAC as version 10.0
Best thing to do is to go back to your project. Click the "Show All Files" icon on the toolbar in the Solution Explorer window. That now shows the References node. Expand it and select the PowerPacks reference. In the Properties window, change the Copy Local property to True.

With these it helps It's the static and nonstatic methods of class String that perform splits, replaces etc.
MSDN String Class
code :
public static class Utils {
    public static string Left(this string str, int length)
    {
        return str.Substring(0, Math.Min(length, str.Length));
    } 
}
var s = "foobar".Left(3)
// variable s will now contain "foo"

I wish did fix the issue. [This isn't exactly an answer but it is a solution that works in place of the above assembly.]
I built this class to replace the functionality provided by the FileIO.TextFieldParser in Microsoft.VisualBasic and to be API compliant with it. The below only provides the functionality I needed so expand as desired.
code :
public class TextFieldParser : StreamReader, IDisposable
{
    int iToken = 1;
    bool quoted = false;
    char[] delimiters;
    string curLine;

    public TextFieldParser(string path) : base(path) { }

    public TextFieldParser(Stream stream) : base(stream) { }

    public string[] ReadFields()
    {
        curLine = ReadLine();

        return GetFields();
    }

    public void SetDelimiters(string delim)
    {
        delimiters = delim.ToCharArray();
    }

    public string[] GetFields()
    {
        if (delimiters == null || delimiters.Length == 0)
            throw new Exception($"{GetType().Name} requires delimiters be defined to identify fields.");

        if (!hasFieldsEnclosedInQuotes)
        {
            return curLine.Split(delimiters);
        }
        else
        {
            var token = (char)iToken;
            var sb = new StringBuilder();

            // Go through the string and change delimiters to token
            // ignoring them if within quotes if indicated
            for (int c = 0; c < curLine.Length; c++)
            {
                var qc = curLine[c];

                if (hasFieldsEnclosedInQuotes && qc == '"')
                {
                    quoted = !quoted;
                    continue;
                }
                else if (!quoted)
                {
                    // Replace the delimiters with token
                    for (int d = 0; d < delimiters.Length; d++)
                    {
                        if (qc == delimiters[d])
                        {
                            qc = token;
                            break;
                        }
                    }
                }

                sb.Append(qc);
            }

            return sb.ToString().Split(token);
        }
    }

    private bool hasFieldsEnclosedInQuotes = false;
    public bool HasFieldsEnclosedInQuotes
    {
        get { return hasFieldsEnclosedInQuotes; }
        set { hasFieldsEnclosedInQuotes = value; }
    }

    public bool EndOfData
    {
        get { return EndOfStream; }
    }
