CodePointCount(ICharSequence, Int32, Int32)
Returns the number of Unicode code points in the text range of the specified char sequence.
[Android.Runtime.Register("codePointCount", "(Ljava/lang/CharSequence;II)I", "")]
public static int CodePointCount(Java.Lang.ICharSequence seq, int beginIndex, int endIndex);[<Android.Runtime.Register("codePointCount", "(Ljava/lang/CharSequence;II)I", "")>]
static member CodePointCount : Java.Lang.ICharSequence * int * int -> intParameters
- seq
- ICharSequence
the char sequence
- beginIndex
- Int32
the index to the first char of
the text range.
- endIndex
- Int32
the index after the last char of
the text range.
Returns
the number of Unicode code points in the specified text range
- Attributes
Exceptions
if seq is null.
if beginIndex , beginIndex > endIndex or
if endIndex is greater than the length of seq.
Remarks
Returns the number of Unicode code points in the text range of the specified char sequence. The text range begins at the specified beginIndex and extends to the char at index endIndex - 1. Thus the length (in chars) of the text range is endIndex-beginIndex. Unpaired surrogates within the text range count as one code point each.

Applies to
CodePointCount(Char[], Int32, Int32)
Returns the number of Unicode code points in a subarray of the
char array argument.
[Android.Runtime.Register("codePointCount", "([CII)I", "")]
public static int CodePointCount(char[]? a, int offset, int count);[<Android.Runtime.Register("codePointCount", "([CII)I", "")>]
static member CodePointCount : char[] * int * int -> intParameters
- a
- Char[]
the char array
- offset
- Int32
the index of the first char in the
given char array
- count
- Int32
the length of the subarray in chars
Returns
the number of Unicode code points in the specified subarray
- Attributes
Exceptions
if seq is null.
if offset , count or if
offset + count is greater than the length of
seq.
Remarks
Returns the number of Unicode code points in a subarray of the char array argument. The offset argument is the index of the first char of the subarray and the count argument specifies the length of the subarray in chars. Unpaired surrogates within the subarray count as one code point each.
