System.Text.UTF7Encoding.GetByteCount Method

Calculates the number of bytes produced by encoding a set of characters from the specified character array.

Syntax

public override int GetByteCount (char[] chars, int index, int count)

Parameters

chars
The character array containing the set of characters to encode.
index
The index of the first character to encode.
count
The number of characters to encode.

Returns

The number of bytes produced by encoding the specified characters.

Remarks

To calculate the exact array size required by UTF7Encoding.GetBytes(string, int, int, Byte[], int) 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.
