UnicodeEncoding.GetCharCount Method (Byte*, Int32)
Assembly: mscorlib (in mscorlib.dll)
[CLSCompliantAttribute(false)] [ComVisibleAttribute(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)(Nothing).
count is less than zero.
The resulting number of bytes is greater than the maximum number that can be returned as an integer.
Error detection is enabled, and bytes contains an invalid sequence of bytes.
A fallback occurred (see Understanding Encodings for fuller explanation)
To calculate the exact array size that GetChars requires to store the resulting characters, the application uses GetCharCount. To calculate the maximum array size, the application should use GetMaxCharCount. The GetCharCount method generally allows allocation of less memory, while the GetMaxCharCount method generally executes faster.
With error detection, an invalid sequence causes this method to throw a ArgumentException. Without error detection, invalid sequences are ignored, and no exception is thrown.
