Encoding::GetByteCount Method (String)

When overridden in a derived class, calculates the number of bytes produced by encoding the characters in the specified string.

Namespace:  System.Text
Assembly:  mscorlib (in mscorlib.dll)

No code example is currently available or this language may not be supported.

Parameters

s
Type: System::String
The string that contains the set of characters to encode.

Return Value

Type: System::Int32
The number of bytes produced by encoding the specified characters.

ExceptionCondition
ArgumentNullException

s is nullptr.

EncoderFallbackException

A fallback occurred (see Understanding Encodings for complete explanation).

To calculate the exact array size required by GetBytes to store the resulting bytes, the application should use GetByteCount. To calculate the maximum array size, the application should use GetMaxByteCount. The GetByteCount method generally allocates less memory, while the GetMaxByteCount method generally executes faster.

For a discussion of programming considerations for use of this method, see the Encoding class description.

The following code example determines the number of bytes required to encode a string or a range in the string, encodes the characters, and displays the resulting bytes.
