I'm writing a simple program where a user would type in a full name separated by spaces. When "btnGetName" is pressed, the program will analyze the text box and extract the first name and place it in the first name label, the middle name in the middle name label and finally the last name into the last name label.

Using an if/then/else.

    if (myarray.count==1)

                {

                    lblLast.text=myarray[0].ToString();

                    //I would wipe out the contents in the other labels here

                 }

               else if(myarray.count==2)

                {

                    ...

                }

How would I go about creating something like this.

If only one name is entered (Smith), assume it is the last name and leave first and middle names blank

If two entries are made (Joe Smith) assume it is the first and last.

If there are three entries in the text box, assume this includes first, middle and last names.

If no entries are made leave all labels empty.

If more than three entries are made give the user an error message, wipe the text box and place the cursor back into the text box.

Prevent an error from occurring using if/then or try/catch.

First, you should check the text box is empty or not. If its empty no analyzing is needed. 



if(textbox1.Text == ""){

    lblFirstName.Text = "";

    lblMiddleName.Text = "";

    lblLastName.Text = "";



}else{



    String nameArr = textbox1.Text.Split(' ');



    int wordCount = nameArr.count;

    switch(wordCount){

        case 1 :    lblFirstName.Text = "";

                    lblMiddleName.Text = "";

                    lblLastName.Text = nameArr[0];

                    break;



        case 2 :    lblFirstName.Text = nameArr[0];

                    lblMiddleName.Text = "";

                    lblLastName.Text = nameArr[1];

                    break;



        case 3 :    lblFirstName.Text = nameArr[0];

                    lblMiddleName.Text = nameArr[1];

                    lblLastName.Text = nameArr[2];

                    break;



        default:    lblFirstName.Text = "";

                    lblMiddleName.Text = "";

                    lblLastName.Text = "";

                    break;

    }

}
