C# Convert FromBase64CharArray

Description

Convert FromBase64CharArray converts a subset of a Unicode character array, which encodes binary data as base-64 digits, to an equivalent 8-bit unsigned integer array. Parameters specify the subset in the input array and the number of elements to convert.

Syntax

Convert.FromBase64CharArray has the following syntax.

public static byte[] FromBase64CharArray(
  char[] inArray,
  int offset,//from  ww  w. j a  v  a2s.c o m
  int length
)

Parameters

Convert.FromBase64CharArray has the following parameters.

• inArray - A Unicode character array.
• offset - A position within inArray.
• length - The number of elements in inArray to convert.

Returns

Convert.FromBase64CharArray method returns

Example

The following example demonstrates the use of the FromBase64CharArray(Char[], Int32, Int32) method to decode UUencoded (base-64) data and save it as binary output.

//from ww w.  java  2 s .co  m
using System;
public class MainClass
{
    public static void Main(String[] argv)
    {
        System.IO.StreamReader inFile = new System.IO.StreamReader("java2s.txt");
        char[] base64CharArray = new char[inFile.BaseStream.Length];

        byte[] binaryData;
        binaryData = System.Convert.FromBase64CharArray(base64CharArray,
                                         0,
                                         base64CharArray.Length);
    }
}

The code above generates the following result.
