How do you convert an image from a path on the user's computer to a base64 string in C#?
For example, I have the path to the image (in the format C:/image/1.gif) and would like to have a data URI like data:image/gif;base64,/9j/4AAQSkZJRgABAgEAYABgAAD.. representing the 1.gif image returned.
Try this
using (Image image = Image.FromFile(Path))
{
using (MemoryStream m = new MemoryStream())
{
image.Save(m, image.RawFormat);
byte[] imageBytes = m.ToArray();
// Convert byte[] to Base64 String
string base64String = Convert.ToBase64String(imageBytes);
return base64String;
}
}
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)));
Since most of us like oneliners:
Convert.ToBase64String(File.ReadAllBytes(imageFilepath));
If you need it as Base64 byte array:
Encoding.ASCII.GetBytes(Convert.ToBase64String(File.ReadAllBytes(imageFilepath)));
This is the class I wrote for this purpose:
public class Base64Image
{
public static Base64Image Parse(string base64Content)
{
if (string.IsNullOrEmpty(base64Content))
{
throw new ArgumentNullException(nameof(base64Content));
}
int indexOfSemiColon = base64Content.IndexOf(";", StringComparison.OrdinalIgnoreCase);
string dataLabel = base64Content.Substring(0, indexOfSemiColon);
string contentType = dataLabel.Split(':').Last();
var startIndex = base64Content.IndexOf("base64,", StringComparison.OrdinalIgnoreCase) + 7;
var fileContents = base64Content.Substring(startIndex);
var bytes = Convert.FromBase64String(fileContents);
return new Base64Image
{
ContentType = contentType,
FileContents = bytes
};
}
public string ContentType { get; set; }
public byte[] FileContents { get; set; }
public override string ToString()
{
return $"data:{ContentType};base64,{Convert.ToBase64String(FileContents)}";
}
}
var base64Img = new Base64Image {
FileContents = File.ReadAllBytes("Path to image"),
ContentType="image/png"
};
string base64EncodedImg = base64Img.ToString();
You can easily pass the path of the image to retrieve the base64 string
public static string ImageToBase64(string _imagePath)
{
string _base64String = null;
using (System.Drawing.Image _image = System.Drawing.Image.FromFile(_imagePath))
{
using (MemoryStream _mStream = new MemoryStream())
{
_image.Save(_mStream, _image.RawFormat);
byte[] _imageBytes = _mStream.ToArray();
_base64String = Convert.ToBase64String(_imageBytes);
return "data:image/jpg;base64," + _base64String;
}
}
}
Hope this will help.
You can use Server.Map path to give relative path and then you can either create image using base64 conversion or you can just add base64 string to image src.
byte[] imageArray = System.IO.File.ReadAllBytes(Server.MapPath("~/Images/Upload_Image.png"));
string base64ImageRepresentation = Convert.ToBase64String(imageArray);
This code works well with me on DotNet Core 6
using (Image image = Image.FromFile(path))
{
using (MemoryStream m = new MemoryStream())
{
image.Save(m, ImageFormat.Jpeg);
byte[] imageBytes = m.ToArray();
// Convert byte[] to Base64 String
string base64String = Convert.ToBase64String(imageBytes);
// In my case I didn't find the part "data:image/png;base64,", so I added.
return $"data:image/png;base64,{base64String}";
}
}
That way it's simpler, where you pass the image and then pass the format.
private static string ImageToBase64(Image image)
{
var imageStream = new MemoryStream();
try
{
image.Save(imageStream, System.Drawing.Imaging.ImageFormat.Bmp);
imageStream.Position = 0;
var imageBytes = imageStream.ToArray();
var ImageBase64 = Convert.ToBase64String(imageBytes);
return ImageBase64;
}
catch (Exception ex)
{
return "Error converting image to base64!";
}
finally
{
imageStream.Dispose;
}
}
Based on top voted answer, updated for C# 8. Following can be used out of the box. Added explicit System.Drawing before Image as one might be using that class from other namespace defaultly.
public static string ImagePathToBase64(string path)
{
using System.Drawing.Image image = System.Drawing.Image.FromFile(path);
using MemoryStream m = new MemoryStream();
image.Save(m, image.RawFormat);
byte[] imageBytes = m.ToArray();
tring base64String = Convert.ToBase64String(imageBytes);
return base64String;
}
The following piece of code works for me:
string image_path="physical path of your image";
byte[] byes_array = System.IO.File.ReadAllBytes(Server.MapPath(image_path));
string base64String = Convert.ToBase64String(byes_array);
The reverse of this for the googlers arriving here (there is no SO quesion/answer to that)
public static byte[] BytesFromBase64ImageString(string imageData)
{
var trunc = imageData.Split(',')[1];
var padded = trunc.PadRight(trunc.Length + (4 - trunc.Length % 4) % 4, '=');
return Convert.FromBase64String(padded);
}
Something like that
Function imgTo64(ByVal thePath As String) As String
Dim img As System.Drawing.Image = System.Drawing.Image.FromFile(thePath)
Dim m As IO.MemoryStream = New IO.MemoryStream()
img.Save(m, img.RawFormat)
Dim imageBytes As Byte() = m.ToArray
img.Dispose()
Dim str64 = Convert.ToBase64String(imageBytes)
Return str64
End Function
I'm trying to send an e-mail with embedded images. Here's what I'm doing...
I have a tinymce text editor where a user can select an image with accompanying text. The e-mail is sent successfully (using CDOSYS - email provider is zohomail) except none of the images are displayed in the e-mail.
Anyone able to tell me what I need to do to display images in an e-mail?
The key function I'm using to convert the image tags to a linked resources is below (uses the agility pack - Install-Package HtmlAgilityPack -Version 1.6.5):
public string ConvertToHtmlDocument(string originalText)
{
HtmlDocument document = new HtmlDocument();
document.LoadHtml(originalText);
document.DocumentNode.Descendants("img").ToList();
foreach(var d in document.DocumentNode.Descendants("img").ToList())
{
string base64String = "";
string currentSrcValue = d.GetAttributeValue("src", null);
string mimeType = MimeMapping.GetMimeMapping(Server.MapPath(currentSrcValue));
using (Image image = Image.FromFile(Server.MapPath(currentSrcValue)))
{
using (MemoryStream m = new MemoryStream())
{
image.Save(m, image.RawFormat);
byte[] imageBytes = m.ToArray();
// Convert byte[] to Base64 String
base64String = Convert.ToBase64String(imageBytes);
}
}
//currentSrcValue = currentSrcValue.Split(',')[1];//Base64 part of string
byte[] imageData = Convert.FromBase64String(base64String);
string contentId = Guid.NewGuid().ToString();
LinkedResource inline = new LinkedResource(new MemoryStream(imageData), mimeType);
inline.ContentId = contentId;
inline.TransferEncoding = TransferEncoding.Base64;
d.SetAttributeValue("src", "cid:" + inline.ContentId);
}
return document.DocumentNode.OuterHtml;
}

I am trying to create an API which will save an image at a given location .
Below is my Code for that
Image image = Image.FromFile(#"C:\Users\abc\Desktop\img-logo.jpg");
byte[] bytes = (byte[])(new ImageConverter()).ConvertTo(image, typeof(byte[]));
string str = Convert.ToBase64String(bytes);
Save_Application_Image("12004", str);
and the method in API
public void Save_Application_Image(string staffCode , string bytearray)
{
try
{
byte[] bytes = Convert.FromBase64String(bytearray);
file_path = "~/uploads/" + file_name;
FileStream file = File.Create(HttpContext.Current.Server.MapPath(file_path));
file.Write(bytes, 0, bytes.Length);
file.Close();
}
catch(Exception ex)
{
logger.LogError(ex);
}
finally
{
}
}
This api has to be called from Android Application so I will receive two string parameter.
It is saving the file perfectly but file is not readable. No preview for image file.
What is the right approach for this ?
I'm unsure of how the ImageConverter works, but I've used this before to convert Images to byte[]:
Image image = Image.FromFile(#"C:\Users\abc\Desktop\img-logo.jpg");
using (var stream = new MemoryStream())
{
image.Save(stream);
string savedImage = Convert.ToBase64String(stream.ToArray());
Save_Application_Image("12004", str);
}
I want to save base64 image to a folder in application, but I have a problem in code. it gives an error as below,
Message = "Invalid length for a Base-64 char array or string."
In my code;
public static string UpdateUser(int refuser, string name, string surname,string base64)
{
string result = "FAILED";
var photo = "";
if (base64!=null && base64!="")
{
string mediaPath = Extend.GetXmlConfigParameter("media", "path")+"User\\";
string mediaName = Guid.NewGuid().ToString();
base64 = base64.Replace("data:image/png;base64,", "");
base64 = base64.Replace("data:image/jpg;base64,", "");
base64 = base64.Replace("data:image/gif;base64,", "");
base64 = base64.Replace("data:image/jpeg;base64,", "");
string filePath = mediaPath + mediaName + ".png";
try
{
byte[] bytes = Convert.FromBase64String(base64);
Image image;
using (MemoryStream ms = new MemoryStream(bytes))
{
image = Image.FromStream(ms);
}
image.Save(filePath, System.Drawing.Imaging.ImageFormat.Png);
//File.WriteAllBytes(filePath, Convert.FromBase64String(base64));
photo = mediaName + ".png";
}
catch(Exception ex)
{
Logger.LogError(ex.Message, ex.StackTrace);
return result;
}
}
try
{
DataSet ds = Database.GetDataSet(con, Database.CreateSpQuery("mobile_user_update ",
new List<object> {
refuser,
name,
surname,
photo
}));
if (!Database.IsDataSetValid(ds))
return null;
result = Database.GetString(ds.Tables[0].Rows[0]["Result"]);
}
catch (Exception ex)
{
Logger.LogError(ex.Message, ex.StackTrace);
}
return result;
}
when i try to convert to byte array with below step in code
byte[] bytes = Convert.FromBase64String(base64);

How can I solve this problem.
Thanks in advance.
It looks that you getting this base64 string through url. If so, you should encode it , before it send to the client.
HttpUtility.UrlEncode(base64string)
I have web application which will convert image to base64 string. pass it to WCF service and serivce methods will convert the string back to png image.
Client Side (Convert Image to Base 64)
public static string ImageToBase64(string path)
{
using (Image image = Image.FromFile(path))
{
using (MemoryStream m = new MemoryStream())
{
image.Save(m, image.RawFormat);
byte[] imageBytes = m.ToArray();
// Convert byte[] to Base64 String
string base64String = Convert.ToBase64String(imageBytes);
return base64String;
}
}
}
WCF Serive Method
CommonDataManager.Base64ToImage(designImage).Save(designQuotePath + "/" + "Request_Quote_" + objQuote.Customer_Id.ToString(), ImageFormat.Png);
public static Image Base64ToImage(string base64String)
{
Image image = null;
try
{
byte[] imageBytes = System.Convert.FromBase64String(base64String);
using (MemoryStream ms = new MemoryStream(imageBytes, 0, imageBytes.Length))
{
image = Image.FromStream(ms, true);
}
}
catch (Exception ex)
{
LogManager.LogException(ex, "Base64ToImage");
}
return image;
}
Issues :
It is giving output as normal file not .png file.
Is there any special things need to be checked before sending base64 string to wcf service method as parameter ?
Thanks in advance.
You need to add the extension. Update this:
CommonDataManager.Base64ToImage(designImage).Save(designQuotePath + "/" +
"Request_Quote_" + objQuote.Customer_Id.ToString(), ImageFormat.Png);
To
CommonDataManager.Base64ToImage(designImage).Save(designQuotePath + "/" +
"Request_Quote_" + objQuote.Customer_Id.ToString() + ".png", ImageFormat.Png);
