从文件系统获取图像并使用HttpClient将其发送到C#中的API的好方法

using System;
using System.IO;
using System.Net.Http;
using System.Threading.Tasks;

public class ImageUploader
{
    public async Task UploadImage(string imagePath, string apiUrl)
    {
        // 从文件系统中获取图像
        byte[] imageData = File.ReadAllBytes(imagePath);

        // 创建HttpClient对象
        using (HttpClient client = new HttpClient())
        {
            // 构建HTTP请求
            using (MultipartFormDataContent content = new MultipartFormDataContent())
            {
                // 将图像数据添加到请求内容中
                ByteArrayContent imageContent = new ByteArrayContent(imageData);
                content.Add(imageContent, "image", "image.jpg");

                // 发送POST请求
                HttpResponseMessage response = await client.PostAsync(apiUrl, content);

                // 处理响应
                if (response.IsSuccessStatusCode)
                {
                    Console.WriteLine("图像上传成功！");
                }
                else
                {
                    Console.WriteLine("图像上传失败！");
                }
            }
        }
    }
}
