我如何计算百分比进展，我一直在获得负数？

问题描述

结果我得到的是所有的时间负数

在一种新的形式，我添加了一个长变量：

 长totalBytes = 0; 
公共静态INT fileuploadpercentages = 0; 
  

然后我有这样的事件：

 私人无效videosInsertRequest_ProgressChanged（IUploadProgress OBJ）
 {
 stringProgressReport [1] = obj.Status.ToString（）; 
如果（stringProgressReport [1] ==上传）
 {
 fileuploadpercentages =（int）的Math.Round（（（双）obj.BytesSent）/ totalBytes * 100）; 
 uploadstatus =上传文件; 
} 
} 
  

当我使用就行了一个破发点

  fileuploadpercentages =（int）的Math.Round（（（双）obj.BytesSent）/ totalBytes * 100）; 
  

我看到BytesSent = 786432个
然后我继续下去。

现在我看到BytesSent = 1572864

下一页BytesSent = 2359296

的

问题是totalBytes所有的时间0

我想要得到的是百分比进度1％2％3％......直到100％，如果它的跳跃是不可能的。那些1％，2％，3％，那么其他的跳跃，但我想在fileuploadpercentages百分比上传进度

负数我fileuploadpercentages得到的是：-2147483648

这事件是我使用YouTube的上传文件的一部分。
这是我上传的方法到YouTube：在这个方法我注册到1videosInsertRequest_ProgressChanged1事件

  UserCredential UC = NULL ; 
私人无效UploadVideo（字符串文件名，字符串VideoTitle，串影片说明）
 {
试
 {
变种youtubeService =新YouTubeService（新BaseClientService.Initializer（）
 {
 HttpClientInitializer =凭证，
 =应用程序名称Assembly.GetExecutingAssembly（）的GetName（）名称
。}）; 
 
 video.Snippet =新VideoSnippet（）; 
 video.Snippet.Title = VideoTitle; 
 video.Snippet.Description =视频描述; 
 video.Snippet.Tags =新的字符串[] {TAG1，标签2}; 
 video.Status =新VideoStatus（）; 
 video.Status.PrivacyStatus =公开;使用
（VAR FILESTREAM =新的FileStream（文件名，FileMode.Open））
 {
 const int的KB = 0x400的; 
 VAR minimumChunkSize = 256 * KB; 
 
 VAR videosInsertRequest = youtubeService.Videos.Insert（视频，
片段，状态，文件流，视频/ *）; 
 videosInsertRequest.ProgressChanged + = videosInsertRequest_ProgressChanged; 
 videosInsertRequest.ResponseReceived + = 
 videosInsertRequest_ResponseReceived; 
 //默认块大小为10MB，这里将使用1MB。 
 videosInsertRequest.ChunkSize = minimumChunkSize * 3; 
 DT = DateTime.Now; 
 videosInsertRequest.Upload（）; 
} 
} 
赶上（例外错误）
 {
串errorss = errors.ToString（）; 
} 
} 
  

解决方案

初始化 totalBytes = fileStream.Length; 在 videosInsertRequest.Upload（）;

The result I get is all the time a negative number.

In a new form, I added a long variable:

long totalBytes = 0;
public static int fileuploadpercentages = 0;

Then I have this event:

private void videosInsertRequest_ProgressChanged(IUploadProgress obj)
{            
    stringProgressReport[1] = obj.Status.ToString();
    if (stringProgressReport[1] == "Uploading")
    {
        fileuploadpercentages = (int)Math.Round(((double)obj.BytesSent) / totalBytes * 100);
        uploadstatus = "uploading file";
    }
}

When I'm using a break point on the line:

fileuploadpercentages = (int)Math.Round(((double)obj.BytesSent) / totalBytes * 100);

I see that BytesSent = 786432Then I continue.

Now I see that BytesSent = 1572864

Next BytesSent = 2359296

The problem is totalBytes all the time 0

What I want to get is the percentages progress 1% 2% 3%...untill 100% if it's not possible in jumps of ones 1% 2% 3% then other jumps but i want to get in fileuploadpercentages the percentages upload progress.

The negative number i get in fileuploadpercentages is: -2147483648

This event is part of the youtube file upload I'm using.This is my upload method to youtube: In this method I register to the 1videosInsertRequest_ProgressChanged1 event.

UserCredential uc = null;
private void UploadVideo(string FileName, string VideoTitle, string VideoDescription)
{
    try
    {
        var youtubeService = new YouTubeService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
            ApplicationName = Assembly.GetExecutingAssembly().GetName().Name
        });

        video.Snippet = new VideoSnippet();
        video.Snippet.Title = VideoTitle;
        video.Snippet.Description = VideoDescription;
        video.Snippet.Tags = new string[] { "tag1", "tag2" };
        video.Status = new VideoStatus();
        video.Status.PrivacyStatus = "public";
        using (var fileStream = new FileStream(FileName, FileMode.Open))
        {
            const int KB = 0x400;
            var minimumChunkSize = 256 * KB;

            var videosInsertRequest = youtubeService.Videos.Insert(video,
                        "snippet,status", fileStream, "video/*");
            videosInsertRequest.ProgressChanged +=videosInsertRequest_ProgressChanged;
            videosInsertRequest.ResponseReceived +=
            videosInsertRequest_ResponseReceived;
            // The default chunk size is 10MB, here will use 1MB.
            videosInsertRequest.ChunkSize = minimumChunkSize * 3;
            dt = DateTime.Now;
            videosInsertRequest.Upload();
        }
    }
    catch (Exception errors)
    {
        string errorss = errors.ToString();
    }
}

解决方案

Initialize totalBytes = fileStream.Length; before videosInsertRequest.Upload();
