Calculates the number of bytes produced by encoding a set of characters starting at the specified character pointer.
The number of bytes produced by encoding the specified characters.
To calculate the exact array size that UTF7Encoding.GetBytes(string, int, int, Byte[], int) requires to store the resulting bytes, the application uses UTF7Encoding.GetByteCount(Char[], int, int). To calculate the maximum array size, the application should use UTF7Encoding.GetMaxByteCount(int). The UTF7Encoding.GetByteCount(Char[], int, int) method generally allows allocation of less memory, while the UTF7Encoding.GetMaxByteCount(int) method generally executes faster.
