Convert file to base64 string c#

Also the specific encoding model is supported. ToBase64String Encoding. GetBytes "sample input" ; It's better to create an extension method to encode a base64 string. GetBytes plainText ; return Convert. EncodeBase64 ; Console. EncodeBase64 Encoding. Unicode ; Console.

Converts the value of an array of 8-bit unsigned integers to its equivalent string representation that is encoded with base digits. Converts a subset of an array of 8-bit unsigned integers to its equivalent string representation that is encoded with base digits.

Parameters specify the subset as an offset in the input array, the number of elements in the array to convert, and whether to insert line breaks in the return value. Parameters specify the subset as an offset in the input array, and the number of elements in the array to convert.

Converts an array of 8-bit unsigned integers to its equivalent string representation that is encoded with base digits. You can specify whether to insert line breaks in the return value. Converts the 8-bit unsigned integers inside the specified read-only span into their equivalent string representation that is encoded with base digits.

You can optionally specify whether to insert line breaks in the return value. InsertLineBreaks to insert a line break every 76 characters, or None to not insert line breaks. The string representation in base 64 of length elements of inArray , starting at position offset. The following example demonstrates the ToBase64String method. The input is divided into groups of three bytes 24 bits each. Consequently, each group consists of four 6-bit numbers where each number ranges from decimal 0 to In this example, there are 85 3-byte groups with one byte remaining.

The first group consists of the hexadecimal values 00, 01, and 02, which yield four 6-bit values equal to decimal 0, 0, 4, and 2. Those four values correspond to the base digits "A", "A", "E", and "C" at the beginning of the output. If an integral number of 3-byte groups does not exist, the remaining bytes are effectively padded with zeros to form a complete group. Asked 12 years, 3 months ago. Active today.
