Convert.ToBase64String Method (Byte, Int32, Int32)
Converts a subset of an array of 8-bit unsigned integers to its equivalent string representation that is encoded with base-64 digits. Parameters specify the subset as an offset in the input array, and the number of elements in the array to convert.
Assembly: mscorlib (in mscorlib.dll)
An array of 8-bit unsigned integers.
An offset in inArray.
The number of elements of inArray to convert.
Return ValueType: System.String
The string representation in base 64 of length elements of inArray, starting at position offset.
The elements of inArray are taken as a numeric value and converted to a string representation in base 64.
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 offset parameter is zero-based.
