Parameters

chars

The char array to encode as a System.Text.UTF8Encoding .

index

A int that specifies the first index of chars to encode.

count

A int that specifies the number of characters to encode.

Returns

A int containing the number of bytes necessary to encode the range in chars from index to index + count - 1 as a System.Text.UTF8Encoding.

Exceptions

Type	Reason
ArgumentNullException	chars is null .
ArgumentOutOfRangeException	The return value is greater than int.MaxValue. -or- index or count is less than zero. -or- index and count do not specify a valid range in chars (i.e. (index + count) > chars.Length).
ArgumentException	Error-checking is turned on for the current instance and chars contains an invalid surrogate sequence.

Remarks

If error-checking is turned off and an invalid surrogate sequence is detected, the invalid characters are ignored and do not affect the return value, and no exception is thrown.

Note:

This method overrides Encoder.GetByteCount(Char[], int, int, bool) .
