textbox

How to put a specific character in specific place in textbox?
for example, i have to put "/" into fifth pace in textbox with max lenght of 7 characters.
So, when user starts writing something "/" is in fifth position and he can't remove it.

Try this:
strPhone = objPhoneFormat.AddMask("99999/99", strPhone);

public string AddMask(object ImaskFormat, object IActText)
  {
   int maskLen;
   int strCount;
   string maskDelimiter;
   strCount = 0;
   string strResult = string.Empty;
                      try
            {
                for (maskLen = 0; maskLen < ImaskFormat.ToString().Length; maskLen++)
                {
                    maskDelimiter = ImaskFormat.ToString().Substring(maskLen, 1).ToUpper();
                    if (maskDelimiter != "9" & maskDelimiter != "X" & maskDelimiter != "A")
                    {
                        strResult += maskDelimiter;
                    }
                    else
                    {
                        strResult += IActText.ToString().Substring(strCount, 1);
                        strCount += 1;
                    }
                }
            }
            catch
            {
                strResult = IActText.ToString();
            }
            finally
            {
            }
   return strResult;
  }

Try this:
strPhone = objPhoneFormat.AddMask("99999/99", strPhone);

public string AddMask(object ImaskFormat, object IActText)
  {
   int maskLen;
   int strCount;
   string maskDelimiter;
   strCount = 0;
   string strResult = string.Empty;
                      try
            {
                for (maskLen = 0; maskLen < ImaskFormat.ToString().Length; maskLen++)
                {
                    maskDelimiter = ImaskFormat.ToString().Substring(maskLen, 1).ToUpper();
                    if (maskDelimiter != "9" & maskDelimiter != "X" & maskDelimiter != "A")
                    {
                        strResult += maskDelimiter;
                    }
                    else
                    {
                        strResult += IActText.ToString().Substring(strCount, 1);
                        strCount += 1;
                    }
                }
            }
            catch
            {
                strResult = IActText.ToString();
            }
            finally
            {
            }
   return strResult;
  }
