C# Word Wrap

private StringBuilder WordWrap(string message, int length)
{
StringBuilder build = new StringBuilder();
length++;
while (!string.IsNullOrWhiteSpace(message))
{
var lineLength = message.Length > length ? length : message.Length;

string line = message.Substring(0, lineLength);
if (!line.EndsWith(" "))
{
var lastSpace = line.LastIndexOf(" ");
if (lastSpace != -1)
lineLength = lastSpace;

line = message.Substring(0, lineLength);

}
build.AppendLine(line);
message = message.Remove(0, lineLength);
message = message.TrimStart();

}
return build;
}

Distance between 2 Points

Search for this on the Internet and it gives you loads of technical details when all you want is a simple example you can use. So here it is

private static double GetlineLength(Point startPoint, Point endPoint)
{
var x = startPoint.X - endPoint.X;
var y = startPoint.Y - endPoint.Y;
return Math.Sqrt(Math.Pow(x, 2) + Math.Pow(y, 2));
}

I hope this ends your search :)

Sample Extension Method

public static class StringExtentionMethods
{
public static int WordCount(this String str)
{
return str.Split(new char[] { ' ', '.', '?' }, StringSplitOptions.RemoveEmptyEntries).Length;
}
}

// C# to convert a string to a byte array.

public static byte[] StrToByteArray(string str)
{
System.Text.ASCIIEncoding encoding=new System.Text.ASCIIEncoding();
return encoding.GetBytes(str);
}

// C# to convert a byte array to a string.

System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
str = enc.GetString(dBytes);

The Other Event Handler

Normally when I declare an Event I do it like this. The Easy way.

public event EventHandler Closing;

But you can have more power if you do it like this.

private EventHandler canClose;
public event EventHandler Closing
{
add { this.canClose += value; }
remove { this.canClose -= value; }
}

You can find out who is registering against your event.
Very handy..

C# Inline If Sample

Sample using WPF

Button newbutton = new Button();
bool a = true;
newbutton.Visibility = a ? System.Windows.Visibility.Visible : System.Windows.Visibility.Collapsed;

(a) being a bool or it could have been String.IsNullEmpty(newbutton.Text)

newbutton.Visibility = !String.IsNullEmpty(newbutton.Text) ? System.Windows.Visibility.Visible : System.Windows.Visibility.Collapsed;

Anything that evaluates to bool. If True do the command after the ? else do the command after the :
