UTF8Encoding.GetCharCount Method (Byte*, Int32)
Assembly: mscorlib (in mscorlib.dll)
[ComVisibleAttribute(false)] [CLSCompliantAttribute(false)] public override int GetCharCount ( byte* bytes, int count )
A pointer to the first byte to decode.
The number of bytes to decode.
Return ValueThe number of characters produced by decoding the specified sequence of bytes.
bytes is a null reference (Nothing in Visual Basic).
count is less than zero.
The resulting number of bytes is greater than the maximum number that can be returned as an int.
Error detection is enabled, and bytes contains an invalid sequence of bytes.
To calculate the exact array size required by GetChars to store the resulting characters, use GetCharCount. To calculate the maximum array size, use GetMaxCharCount. The GetCharCount method generally allows you to allocate less memory, whereas the GetMaxCharCount method generally executes faster.
With error detection, an invalid sequence causes this method to throw an ArgumentException. Without error detection, invalid sequences are ignored, and no exception is thrown.
