[英]How to Convert image (.png) to base64 string, vice a versa and strore it to a specified location
I'm trying to store images (png) to sqlite database in a windows 8 app, and i figured out it can be done by converting it to base64 string and storing the string to the database. 我正在尝试将图像(png)存储到Windows 8应用程序中的sqlite数据库,我发现它可以通过将其转换为base64字符串并将字符串存储到数据库来完成。 Later on in the app i want to convert that base64 string to png image and store it to a specified location. 稍后在应用程序中我想将该base64字符串转换为png图像并将其存储到指定位置。 The Problem is i don't know how to convert images to base64 and base64 to image and store it to a specified location in c# windows 8 app. 问题是我不知道如何将图像转换为base64和base64图像并将其存储到c#windows 8 app中的指定位置。 Any help would be appreciated. 任何帮助,将不胜感激。
public string ImageToBase64(Image image,
System.Drawing.Imaging.ImageFormat format)
{
using (MemoryStream ms = new MemoryStream())
{
// Convert Image to byte[]
image.Save(ms, format);
byte[] imageBytes = ms.ToArray();
// Convert byte[] to Base64 String
return Convert.ToBase64String(imageBytes);
}
}
public Image Base64ToImage(string base64String)
{
// Convert Base64 String to byte[]
byte[] imageBytes = Convert.FromBase64String(base64String);
using (var ms = new MemoryStream(imageBytes, 0, imageBytes.Length))
{
// Convert byte[] to Image
ms.Write(imageBytes, 0, imageBytes.Length);
return Image.FromStream(ms, true);
}
}
