我正在使用WCF连续地将图像从服务器流式传输到客户端。但是,每当我尝试运行它时,我总是会收到此错误:
位于“本地主机地址”的HTTP服务太忙了。
我在网上到处寻找其他解决方案。我尝试过限制,增加缓冲区大小,并改变传输模式无济于事。我对WCF很新,不知道还能去哪里。如果有人知道如何摆脱这个错误,我将不胜感激。谢谢!这是我的所有代码。

Client.cs文件和ClientWCF功能:
public Form1()
{
private VisionWcfClient client = new VisionWcfClient();
client.Connect();
pictureBox2.Image = ConvertByteArrayToImage(client.GetVideoStream());
}
public byte[] GetVideoStream()
{
return m_clientProxy.GetVideoStream();
}
Server.cs文件和ServerWCF功能:
public byte[] GetVideoStream()
{
return GetVideoStreamEvent();
}
byte[] ads_GetVideoStreamEvent()
{
IntPtr pointer;
m_Buffers.GetAddress(out pointer);
Bitmap b = new Bitmap(m_Buffers.Width, m_Buffers.Height, m_Buffers.Pitch, System.Drawing.Imaging.PixelFormat.Format8bppIndexed, pointer);
System.Drawing.Imaging.ColorPalette palette = b.Palette;
Color[] entries = palette.Entries;
for (int i = 0; i < 256; i++)
entries[i] = Color.FromArgb(255, i, i, i);
b.Palette = palette;
m_Buffers.ReleaseAddress(pointer);
using (MemoryStream ms = new MemoryStream())
{
b.Save(ms, ImageFormat.Bmp);
return ms.ToArray();
}

我遇到了同样的问题......问题是链接到运行我的服务的应用程序池的帐户密码已更改。
将AppPool与有效凭证相关联后,该服务再次开始正常运行。

你说你是“不断”流式传输图像,这是否意味着你在循环中这样做?
更新: 我建议您打开WCF跟踪以帮助确定问题。请在此处查看此信息:

此外,您在服务方法和界面上定义了哪些服务属性?

想出来。我将端口号从8002更改为8003并且有效。不知道为什么,但只要它有效,我就不在乎。
