ASP.NET uses custom functions to switch between uppercase and lowercase strings

This article describes an example of ASP.NET using custom functions to switch the case of strings.Share it for your reference.The implementation is as follows:

Method 1:

public string ToggleCase(string input)
{
  string result = string.Empty;
  char[] inputArray = input.ToCharArray();
  foreach (char c in inputArray)
  {
    if (char.IsLower(c))
      result += c.ToString().ToUpper();
    else if (char.IsUpper(c))
      result += c.ToString().ToLower();
    else
      result += c.ToString();
  }
  return result;
}

Method 2:

public string ToggleCase(string input)
{
  string result = string.Empty;
  char[] inputArray = input.ToCharArray();
  foreach (char c in inputArray)
  {
    if (char.IsLower(c))
      result += Char.ToUpper(c);
    else
      result += Char.ToLower(c);
  }
  return result;
}

I hope that the description in this paper will be helpful to everyone's ASP.NET program design.
