CodePointAt(ICharSequence, Int32)
Returns the code point at the given index of the
CharSequence.
[Android.Runtime.Register("codePointAt", "(Ljava/lang/CharSequence;I)I", "")]
public static int CodePointAt(Java.Lang.ICharSequence seq, int index);[<Android.Runtime.Register("codePointAt", "(Ljava/lang/CharSequence;I)I", "")>]
static member CodePointAt : Java.Lang.ICharSequence * int -> intParameters
- seq
- ICharSequence
a sequence of char values (Unicode code
units)
- index
- Int32
the index to the char values (Unicode
code units) in seq to be converted
Returns
the Unicode code point at the given index
- Attributes
Exceptions
if seq is null.
if the index is negative or greater than or equal to
the length of seq.
Remarks
Returns the code point at the given index of the CharSequence. If the char value at the given index in the CharSequence is in the high-surrogate range, the following index is less than the length of the CharSequence, 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.

CodePointAt(Char[], Int32)
Returns the code point at the given index of the
char array.

- a
- Char[]
the char array
- index
- Int32
the index to the char values (Unicode
code units) in the char array to be converted
Returns
the Unicode code point at the given index

if the index is negative or greater than or equal to
the length of seq.
Remarks
Returns the code point at the given index of the char array. If the char value at the given index in the char array is in the high-surrogate range, the following index is less than the length of the char array, 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.
