Create a Windows Application. Place a button in the centre of form. Set the name and text properties of the button to btnMessage and "Show Message" respectively. For displaying Message Box, add following code to the Click event of btnMessage.

protected void btnMessage_Click (object sender, System.EventArgs e)
{
    MessageBox.Show("English Text Example","English Title");
}

On Pressing F5, Form will be displayed and on clicking Show Message. Message Box will be displayed.

Now for displaying Arabic text, type message and title using Arabic characters. The Message is " Urdu Text Example" and "Urdu Title" in Urdu Language.

The message box displayed by clicking Show Message Button will be

The Message box displays Urdu Text(in Arabic Script). but it has some problems. Arabic Script is written from Right to Left(The rightmost character is first character of string, and leftmost is the last character of string). So the text must be right aligned. In the above example both Title and Message are left aligned. Also the Title must be at right and the Close Button should be at left in a RightToLeft Scheme. This can be done by using style attributes as third parameter of MessageBox.Show method. Style Attributes are used to change the visual style and options of Message Box. For Example, for displaying a Cancel button with OK button, MessageBox.OKCancel is used as

MessageBox.Show("Message","Title",MessageBox.OKCancel);

For RightToLeft MessageBox, RTLReading field is used. And for right aligning the text, RightAlign field is used. So in our new example these two are ORed and passed to Show method of MessageBox(you can OR multipe fields to give their style to MessageBox).

In above examples, we use Windows 2000 support to insert Arabic (Urdu) characters to the code. But if the development environment does not have support for writing multilingual characters, then this work can be done by code. The character datatype of C# stores characters as Unicode character. So we can declare variables of character and string type and assign characters and words of different languages to these variables.
