Calculates the number of bytes produced by encoding a set of characters starting at the specified character pointer.
Syntax
[System.Runtime.InteropServices.ComVisible(false)]
public override int GetByteCount (char* chars, int count)
Parameters
- chars
- count
Returns
The number of bytes produced by encoding the specified characters.
Remarks
To calculate the exact array size required by UTF8Encoding.GetBytes(string, int, int, Byte[], int) to store the resulting bytes, the application uses UTF8Encoding.GetByteCount(Char[], int, int). To calculate the maximum array size, the application should use UTF8Encoding.GetMaxByteCount(int). The UTF8Encoding.GetByteCount(Char[], int, int) method generally allows allocation of less memory, while the UTF8Encoding.GetMaxByteCount(int) 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.
To ensure that the encoded bytes are decoded properly, the application should prefix encoded bytes with a preamble.
