Convert.ToBase64CharArray Method (Byte[], Int32, Int32, Char[], Int32)
Converts a subset of an 8-bit unsigned integer array to an equivalent subset of a Unicode character array encoded with base-64 digits. Parameters specify the subsets as offsets in the input and output arrays, and the number of elements in the input array to convert.
Assembly: mscorlib (in mscorlib.dll)
static member ToBase64CharArray : inArray:byte[] * offsetIn:int * length:int * outArray:char[] * offsetOut:int -> int
Parameters
- inArray
-
Type:
System.Byte[]
An input array of 8-bit unsigned integers.
- offsetIn
-
Type:
System.Int32
A position within inArray.
- length
-
Type:
System.Int32
The number of elements of inArray to convert.
- outArray
-
Type:
System.Char[]
An output array of Unicode characters.
- offsetOut
-
Type:
System.Int32
A position within outArray.
| Exception | Condition |
|---|---|
| ArgumentNullException | inArray or outArray is null. |
| ArgumentOutOfRangeException | offsetIn, offsetOut, or length is negative. -or- offsetIn plus length is greater than the length of inArray. -or- offsetOut plus the number of elements to return is greater than the length of outArray. |
The subset of length elements of inArray starting at position offsetIn, are taken as a numeric value and converted to a subset of elements in outArray starting at position offsetOut. The return value indicates the number of converted elements in outArray. The subset of outArray consists of base-64 digits.
The base-64 digits in ascending order from zero are the uppercase characters "A" to "Z", the lowercase characters "a" to "z", the numerals "0" to "9", and the symbols "+" and "/". The valueless character, "=", is used for trailing padding.
The offset and length parameters are 32-bit signed numbers. The offsetIn and offsetOut parameters are zero-based array positions.

The ToBase64CharArraymethod is designed to process a single byte array that contains all the data to be encoded. To create a base-64 character array from a byte stream, use the System.Security.Cryptography.ToBase64Transform class. |
