Answer 1

The TrimEnd method takes an input character array and not a string. The code below from Dot Net Perls, shows a more efficient example of how to perform the same functionality as TrimEnd.

static string TrimTrailingChars(string value)
{
    int removeLength = 0;
    for (int i = value.Length - 1; i >= 0; i--)
    {
        char let = value[i];
        if (let == '?' || let == '!' || let == '.')
        {
            removeLength++;
        }
        else
        {
            break;
        }
    }
    if (removeLength > 0)
    {
        return value.Substring(0, value.Length - removeLength);
    }
    return value;
}
