Diese Methode kürzt einen String auf eine beliebige Länge ohne das, das letzte Wort abgeschnitten wird.

private string CutLongString(string longString, int length)
{
    if (longString.Trim() != string.Empty)
    {
        if (longString.Length > length)
        {
            longString = longString.Substring(0, length);
            int positionLastSpace = longString.LastIndexOf(" ");
            if (positionLastSpace > -1 && positionLastSpace < length)
                longString = longString.Substring(0, positionLastSpace);

            longString += " …";
        }

  1. minimal modernisiert
    [code]
    private string CutLongString(string longString, int length)
    {
    if (string.IsNullOrWhiteSpace(longString)
    return longString;

    if (longString.Length > length)
    {
    longString = longString.Substring(0, length);
    int positionLastSpace = longString.LastIndexOf(“ „);
    if (positionLastSpace > -1 && positionLastSpace < length) longString = longString.Substring(0, positionLastSpace); longString += " …"; } return longString; } [/code]
