Chars

Gets or sets the character at the specified character position in this instance.

OutputVar := instance.Chars[index]
instance.Chars[index] := value

Parameters

index

The zero-based position of the character.
Can be any type that matches IsInteger or var integer.

value

When setting can be var string or instance of MfChar or MfString.

Gets

Returns var string containing the char value at the position of the argument index.

Sets

Sets the char value at the position of the argument index.

Throws

Throws MfArgumentOutOfRangeException if index is outside the bounds of this instance while setting a character.
Throws MfIndexOutOfRangeException if index is outside the bounds of this instance while getting a character.

Remarks

The index parameter is the position of a character within the StringBuilder. The first character in the string is at index 0. The length of a string is the number of characters it contains. The last accessible character of a StringBuilder instance is at index Length - 1.

Example

sb := new MfText.StringBuilder()
nAlphabeticChars := 0
nWhitespace := 0
nPunctuation := 0
sb1 := new MfText.StringBuilder("This is a simple sentence.")
ctr := 0
while (ctr < sb1.Length)
{
   ch := sb1.Chars[ctr]
   if (MfChar.IsLetter(ch))
   {
       nAlphabeticChars++
       ctr++
       continue
   }
   if (MfChar.IsWhiteSpace(ch))
   {
       nWhitespace++
       ctr++
       continue
   }
   if (MfChar.IsPunctuation(ch))
   {
       nPunctuation++
       ctr++
       continue
   }
   ctr++
}
sb.AppendLine(MfString.Format("The sentence '{0}' has:", sb1))
sb.AppendLine(MfString.Format("   Alphabetic characters: {0}", nAlphabeticChars))
sb.AppendLine(MfString.Format("   Whitespace characters: {0}", nWhitespace))
sb.AppendFormat("   Punctuation characters: {0}", nPunctuation)
MsgBox % sb.ToString()
/*
The sentence 'This is a simple sentence.' has:
  Alphabetic characters: 21
  Whitespace characters: 4
  Punctuation characters: 1
