Class StringBuilderExtensions

Appends the string representation of the codePoint argument to this sequence.

The argument is appended to the contents of this sequence. The length of this sequence increases by CharCount(Int32).

The overall effect is exactly as if the argument were converted to a array by the method ToChars(Int32) and the character in that array were then appended to this .

Returns the character (Unicode code point) at the specified index. The index refers to char values (Unicode code units) and ranges from 0 to Length - 1.

If the char value specified at the given index is in the high-surrogate range, the following index is less than the length of this sequence, and the char value at the following index is in the low-surrogate range, then the supplementary code point corresponding to this surrogate pair is returned. Otherwise, the char value at the given index is returned.

Returns the number of Unicode code points in the specified text range of this . The text range begins at the specified beginIndex and extends to the at index endIndex - 1. Thus the length (in s) of the text range is endIndex-beginIndex. Unpaired surrogates within this sequence count as one code point each.

Copies the array from the into a new array and returns it.

Searches for the first index of the specified character. The search for the character starts at the beginning and moves towards the end.

Searches for the index of the specified character. The search for the character starts at the specified offset and moves towards the end.

Causes this character sequence to be replaced by the reverse of the sequence. If there are any surrogate pairs included in the sequence, these are treated as single characters for the reverse operation. Thus, the order of the high-low surrogates is never reversed.

Let n be the character length of this character sequence (not the length in values) just prior to execution of the Reverse(StringBuilder) method. Then the character at index k in the new character sequence is equal to the character at index n-k-1 in the old character sequence.

Note that the reverse operation may result in producing surrogate pairs that were unpaired low-surrogates and high-surrogates before the operation. For example, reversing "\uDC00\uD800" produces "\uD800\uDC00" which is a valid surrogate pair.

Convenience method to wrap a string in a StringBuilderCharSequenceWrapper so a can be used as ICharSequence in .NET.
