Encoding.GetByteCount Method (Char*, Int32)

Note: This method is new in the .NET Framework version 2.0.

When overridden in a derived class, calculates the number of bytes produced by encoding a set of characters starting at the specified character pointer.

This method is not CLS-compliant.  

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

[ComVisibleAttribute(false)] 
[CLSCompliantAttribute(false)] 
public virtual int GetByteCount (
	char* chars,
	int count
)
J# does not support APIs that consume or return unsafe types.
JScript does not support APIs that consume or return unsafe types.

Parameters

chars

A pointer to the first character to encode.

count

The number of characters to encode.

Return Value

The number of bytes produced by encoding the specified characters.

Exception typeCondition

ArgumentNullException

chars is a null reference (Nothing in Visual Basic).

ArgumentOutOfRangeException

count is less than zero.

To calculate the exact array size that GetBytes requires to store the resulting bytes, use GetByteCount. To calculate the maximum array size, use GetMaxByteCount. The GetByteCount method generally allows you to allocate less memory, whereas the GetMaxByteCount method generally executes faster.
