Remove number of words…

Remove number of words at the beginning of string?

Looking for a function that you want to make string only return the last words within the strings? and remove number of words at the beginning Using C#


Windows Form Remove words

This function could help you:
        /// <summary>
        /// Return only last several words  and remove the number of words at the beginning from string.
        /// </summary>
        public static string RemoveFirstWords(string input, int numberWords)
        {
            try
            {
                string[] Split = input.Split(new Char[] { ' ' });
                input = string.Empty; //After passing the words to Split - Empty in again
                for (int i = numberWords; i < Split.Count(); i++)
                {
                    input += Convert.ToString(Split[i]) + " "; //Get Only the last words
                }
                return input;
            }
            catch (Exception)
            {
                // Log the error.
            }
            return string.Empty;
        }
Use the function like this:
private void removeWords_Click(object sender, EventArgs e)
        {
            if (stringToRemove.Text == string.Empty)
            {
                MessageBox.Show("The String is Empty");
            }
            else
            {
                int paramNumOfWords = Convert.ToInt16(numOfwords.Text);
                string returnOnlyLastWords = RemoveFirstWords(stringToRemove.Text.ToString(), paramNumOfWords);
 
                //Return Words
                MessageBox.Show("Return Words: " + returnOnlyLastWords);
            }
        }

System.NullReferenceException

August 23rd, 2009

While trying Telerik component, I got this error System.NullReferenceException - Object reference not set to an instance of an object, I struggle how to find causing this error, And somehow the solution was


From:


ddbImages.Image = ((Image)item.Tag).GetThumbnailImage(20, 20, null, new IntPtr());
ddbImages.Text = item.Text;

To:


if (item != null)
  {
    ddbImages.Image = ((Image)item.Tag).GetThumbnailImage(20, 20, null, new IntPtr());
    ddbImages.Text = item.Text;
  }
