Hello dear friends I'm working on a project and my purpose is to create a TextBox for Xna, I don't know how i can draw a string in aligned in arectangle, cause i don't see any rectangle parameter in function Draw string?

XML

SpriteFont font;
       public void fncWriteStringOnText(string myText,int FontSize,Vector2 position,Color mycolor)
       {
           string BaseDirectory = ".";
           string FontFileName;
           if (FontSize == 14)
           {
               FontFileName = BaseDirectory + "\\Font\\myfont14";
               font = content.Load<SpriteFont>(FontFileName);
           }
           else if (FontSize == 16)
           {
               FontFileName = BaseDirectory + "\\Font\\myfont16";
               font = content.Load<SpriteFont>(FontFileName);
           }
            else if  (FontSize == 18)
           {
               FontFileName = BaseDirectory + "\\Font\\myfont18";
               font = content.Load<SpriteFont>(FontFileName);
           }
           else if (FontSize == 20)
           {
               FontFileName = BaseDirectory + "\\Font\\myfonft20";
               font = content.Load<SpriteFont>(FontFileName);
           }
           else if (FontSize == 22)
           {
               FontFileName = BaseDirectory + "\\Font\\myfont22";
               font = content.Load<SpriteFont>(FontFileName);
           }
           <big>spriteBatch.DrawString(font,myText,position,mycolor);</big>
       }

Its just vector 2D for the position, in Drawstring function.

As it wasn't any helper i was forced to write my code:

This is my Text struct:

SQL

public struct Text
{
    public int key;
    public string myText;
    public int FontSize;
    public Rectangle rect;
    public Color mycolor;
    public string strplaceOfUse;
    public bool ShouldItBeShownInThisScreen;
    public string wrappedString;
    public int HorizontalMargin;
}

This is initialization of my text:

C#

public Text mytext;
mytext.key = 1;
           mytext.HorizontalMargin = 50;
           mytext.mycolor = Color.Blue;
           mytext.rect = new Rectangle((WindowsScreenWidth - 1000) / 2 + mytext.HorizontalMargin, (WindowsScreenHeight - 300) / 2 + 50, 1000 - 1 * mytext.HorizontalMargin, 300);
           mytext.strplaceOfUse = "AddNewWords_Word";
           mytext.ShouldItBeShownInThisScreen = false;
           mytext.myText = "Hello This is a Test and will take time to be practical,so do think about it and make it better and i know you will";
           mytext.FontSize = 22;
           mytext.wrappedString = WrapText(fncGivemeFont(mytext.FontSize), mytext.myText, mytext.rect.Width);

This is initializing the font

XML

public SpriteFont fncGivemeFont(int fontsize)
       {
           string BaseDirectory = ".";
           SpriteFont myfont=null;
           switch (fontsize)
           {
               case 14:
               {
                   myfont = content.Load<SpriteFont>(BaseDirectory + "\\Font\\myfont14");
                   break;
               }
               case 16:
               {
                   myfont = content.Load<SpriteFont>(BaseDirectory + "\\Font\\myfont16");
                   break;
               }
               case 18:
               {
                   myfont = content.Load<SpriteFont>(BaseDirectory + "\\Font\\myfont18");
                   break;
               }
               case 20:
               {
                   myfont = content.Load<SpriteFont>(BaseDirectory + "\\Font\\myfont20");
                   break;
               }
               case 22:
               {
                   myfont = content.Load<SpriteFont>(BaseDirectory + "\\Font\\myfont22");
                   break;
               }
               default:
               {
                   myfont = content.Load<SpriteFont>(BaseDirectory + "\\Font\\myfont14");
                   break;
               }
           }
           return myfont;
       }

This is my alignment function:

XML

public static string WrapText(SpriteFont spriteFont, string text, float maxLineWidth)
       {
           string[] words = text.Split(' ');

           StringBuilder sb = new StringBuilder();

           float lineWidth = 0f;

           float spaceWidth = spriteFont.MeasureString(" ").X;

           foreach (string word in words)
           {
               Vector2 size = spriteFont.MeasureString(word);

               if (lineWidth + size.X < maxLineWidth)
               {
                   sb.Append(word + " ");
                   lineWidth += size.X + spaceWidth;
               }
               else
               {
                   sb.Append("\n" + word + " ");
                   lineWidth = size.X + spaceWidth;
               }
           }

           return sb.ToString();
       }

My drawing function:

C#

 public Text[] myTexts=new Text[1];
//ArrayList=>MyTexts
         myTexts[0] = mytext;

C#

public void DrawTexts(SpriteBatch mybatch)
       {
           for (int i = 0; i < myTexts.Length; i++)
           {
               if (myTexts[i].ShouldItBeShownInThisScreen)
               {
                   mybatch.DrawString(fncGivemeFont(myTexts[i].FontSize), myTexts[i].wrappedString,new Vector2(myTexts[i].rect.Left,myTexts[i].rect.Top),myTexts[i].mycolor);
               }
           }
       }
