问题描述

我是c＃的新手。我正在开发一个iOS项目。我想将图像上传到服务器。所以我想将图像转换为字符串。任何人都可以帮我这样做。

I am new to c#. I am developing an iOS project. i want to upload images to server. So i want to convert image into string. can anyone help me to do this.

我同意将图像上传到服务器的任何方法。

推荐答案

那怎么样？

FileStream stream = new FileStream(imageFilePath, FileMode.Open);
BinaryReader binreader = new BinaryReader(stream);
byte[] buffer = new byte[(int) stream.Length];
buffer = binreader.ReadBytes((int) stream.Length);
string serialized = Convert.ToBase64String(buffer)

如果你有System.Drawing。图像对象而不是文件路径，你可以这样做：

If you have the System.Drawing.Image object instead of a file path, you can do:

System.Drawing.Image image; //initialize it someway
MemoryStream ms = new MemoryStream();
image.Save(ms,System.Drawing.Imaging.ImageFormat.Jpeg); //if it is jpeg
byte[] buffer = ms.ToArray();
string serialized = Convert.ToBase64String(buffer);

然后将'serialiazed'值传递给服务器。

And then you pass the 'serialiazed' value to the server.

如果它能够起作用取决于服务器将如何处理它。

Put if it will work depends on how the server will handle that.
