   foreach(string newstr in Reversewords)
    {
       var strArr = newstr.ToCharArray();
        char[] chaArr= strArr.Reverse(); // error in this line
        sb.Append(chaArr);

    Does `char[] chaArr= strArr.Reverse().ToArray();` work? – Ibrennan208 Aug 27 '22 at 16:31

  • what is Reversewords. – Qwerty Aug 27 '22 at 16:32
  • @Qwerty Looks like it is a collection of strings that are being iterated over. – Ibrennan208 Aug 27 '22 at 16:33

    Or instead of using the LINQ extension method use the static method of the array class `Array.Reverse` https://learn.microsoft.com/en-us/dotnet/api/system.array.reverse?view=net-6.0#system-array-reverse(system-array) – Rand Random Aug 27 '22 at 16:34
  • In NET 5/6/core you might directly use `sb.AppendJoin("", newstr.Reverse());` No need for the intermediate array buffer. https://learn.microsoft.com/en-us/dotnet/api/system.text.stringbuilder.appendjoin?view=net-6.0 – lidqy Aug 27 '22 at 16:47

I think you shuold do this in other way, you can first, turn it to string.

Also you can find some intresting things about this here : IEnumerable<char> to string

You may use JoinAsString("")
