C# WebAPI2.0上传视频

以下是C# WebAPI2.0上传视频的示例代码：

1. WebAPI端代码

[HttpPost]
public async Task<IActionResult> UploadVideo()
{
    var file = Request.Form.Files[0];
    var filePath = "your file path"; // 设置文件保存路径
    using (var stream = new FileStream(filePath, FileMode.Create))
    {
        await file.CopyToAsync(stream);
    }
    return Ok();
}

2. C#客户端代码

public async Task UploadVideo(string filePath)
{
    using (var client = new HttpClient())
    {
        using (var content = new MultipartFormDataContent())
        {
            using (var fileStream = new FileStream(filePath, FileMode.Open))
            {
                content.Add(new StreamContent(fileStream), "file", Path.GetFileName(filePath));
                var response = await client.PostAsync("your WebAPI url", content);
                if (!response.IsSuccessStatusCode)
                {
                    throw new Exception("上传失败");
                }
            }
        }
    }
}

注意：在WebAPI端代码中，需要设置文件保存路径；在C#客户端代码中，需要将文件流添加到MultipartFormDataContent中，并指定文件名和WebAPI的URL。
