IEnumerator.MoveNext()

The .NET Framework defines a text element as a unit of text that is displayed as a single character, that is, a grapheme. A text element can be a base character, a surrogate pair, or a combining character sequence. The Unicode Standard defines a surrogate pair as a coded character representation for a single abstract character that consists of a sequence of two code units, where the first unit of the pair is a high surrogate and the second is a low surrogate. The Unicode Standard defines a combining character sequence as a combination of a base character and one or more combining characters. A surrogate pair can represent a base character or a combining character.

After an enumerator is created or after a Reset is called, the enumerator is positioned before the first text element of the string, and the first call to MoveNext moves the enumerator over the first text element of the string.

If the string is modified after this enumerator was created, MoveNext throws an exception.

After the end of the string is passed, subsequent calls to MoveNext return false until Reset is called.
