ASCIIEncoding.GetCharCount Method (Byte*, Int32)
Calculates the number of characters produced by decoding a sequence of bytes starting at the specified byte pointer.
This API is not CLS-compliant. The CLS-compliant alternative is GetCharCount. Namespace: System.Text
Assembly: mscorlib (in mscorlib.dll)
[CLSCompliantAttribute(false)] [ComVisibleAttribute(false)] public override int GetCharCount( byte* bytes, int count )
- Type: System.Byte*
A pointer to the first byte to decode.
- Type: System.Int32
The number of bytes to decode.
Return ValueType: System.Int32
The number of characters produced by decoding the specified sequence of bytes.
bytes is null.
count is less than zero.
The resulting number of bytes is greater than the maximum number that can be returned as an integer.
A fallback occurred (see Character Encoding in the .NET Framework for complete explanation)
To calculate the exact array size required by GetChars 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.
