Convert.ToBase64CharArray() Method in C#
The Convert.ToBase64CharArray() method in C# is used to convert a subset of an 8-bit unsigned integer array to an equivalent subset of a Unicode character array encoded with base-64 digits.
Syntax
Following is the syntax −
public static int ToBase64CharArray (byte[] arr, int offsetIn, int length, char[] outArray, int offsetOut);
Here,
- arr − An input array of 8-bit unsigned integers.
- offsetIn − A position within arr.
- length − The number of elements of arr to convert.
- outArray − An output array of Unicode characters.
- offsetOut − A position within outArray.
Example
Let us now see an example to implement the Convert.ToBase64CharArray() method −
using System;
public class Demo {
public static void Main(){
byte[] val1 = {5,10,15,20,25,30};
long arrLen = (long)((4.0d / 3.0d) * val1.Length);
if (arrLen % 5 != 0)
arrLen += 5 - arrLen % 5;
char[] base64CharArray = new char[arrLen];
int res = Convert.ToBase64CharArray(val1, 0, val1.Length, base64CharArray, 0);
Console.WriteLine("Bytes (count) = "+ res);
Console.Write("Our base64CharArray...
");
for (int j = 0; j < base64CharArray.Length; j++)
Console.Write("{0}", base64CharArray[j]);
}
}Output
This will produce the following output −
Bytes (count) = 8 Our base64CharArray... BQoPFBke
