Convert an Image (Selected by Path) to Base64 String

Convert an image (selected by path) to base64 string

Get the byte array (byte[]) representation of the image, then use Convert.ToBase64String(), st. like this:

byte[] imageArray = System.IO.File.ReadAllBytes(@"image file path");
string base64ImageRepresentation = Convert.ToBase64String(imageArray);

To convert a base64 image back to a System.Drawing.Image:

var img = Image.FromStream(new MemoryStream(Convert.FromBase64String(base64String)));

Convert Image to Base64 string

StorageFolder storageFolder = ApplicationData.Current.LocalFolder;
StorageFile file1 = await storageFolder.GetFileAsync("Image.png");

string _b64 = Convert.ToBase64String(File.ReadAllBytes(file1.Path));

This worked for me.

How can I convert an image into a Base64 string?

You can use the Base64 Android class:

String encodedImage = Base64.encodeToString(byteArrayImage, Base64.DEFAULT);

You'll have to convert your image into a byte array though. Here's an example:

Bitmap bm = BitmapFactory.decodeFile("/path/to/image.jpg");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG, 100, baos); // bm is the bitmap object
byte[] b = baos.toByteArray();

* Update *

If you're using an older SDK library (because you want it to work on phones with older versions of the OS) you won't have the Base64 class packaged in (since it just came out in API level 8 AKA version 2.2).

You can use react-native-fs if you are using react-native cli

documentation: https://github.com/itinance/react-native-fs#readfilefilepath-string-encoding-string-promisestring

import RNFS from 'react-native-fs';

//base64 res
var data = await RNFS.readFile( "file://path-to-file", 'base64').then(res => { return res });
