UTF7Encoding.GetByteCount Method (Char*, Int32)

 

Calculates the number of bytes produced by encoding a set of characters starting at the specified character pointer.

This API is not CLS-compliant.

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

[SecurityCriticalAttribute]

[ComVisibleAttribute(false)]
public override unsafe int GetByteCount(
	char* chars,
	int count
)

Parameters

chars
Type: System.Char*

A pointer to the first character to encode.

count
Type: System.Int32

The number of characters to encode.

Return Value

Type: System.Int32

The number of bytes produced by encoding the specified characters.

Exception Condition
ArgumentNullException

chars is null (Nothing in Visual Basic .NET).

ArgumentOutOfRangeException

count is less than zero.

-or-

The resulting number of bytes is greater than the maximum number that can be returned as an int.

EncoderFallbackException

A fallback occurred (see Character Encoding in the .NET Framework for complete explanation)

-and-

EncoderFallback is set to EncoderExceptionFallback.

To calculate the exact array size that GetBytes requires to store the resulting bytes, the application uses GetByteCount. To calculate the maximum array size, the application should use GetMaxByteCount. The GetByteCount method generally allows allocation of less memory, while the GetMaxByteCount method generally executes faster.

SecurityCriticalAttribute

Requires full trust for the immediate caller. This member cannot be used by partially trusted or transparent code.
