我正在从数据库中获取值，并尝试使用 UrlHistoryWrapper 类将它们插入到 Internet Explorer 历史记录中。当我将for条件设置为数千时，我会收到此错误，但是，当我将 for 条件设置为小于 100 时，它会运行良好。我检查了内存使用情况，应该没有问题。如果 chrome.URLs 和 firefox.URLs 有数千个值，我怎样才能使这段代码能够运行？

这是我的代码：

UrlHistoryWrapperClass urlHistory;
        UrlHistoryWrapperClass.STATURLEnumerator enumerator;
        List<STATURL> list = new List<STATURL>();
        urlHistory = new UrlHistoryWrapperClass();
        enumerator = urlHistory.GetEnumerator();
        bool display = false;
        chrome.GetHistory(display);
        for (int i = 0; i < chrome.URLs.Count; i++ )
        {
            URL url = chrome.URLs[i];
            urlHistory.AddHistoryEntry(url.url, url.title, ADDURL_FLAG.ADDURL_ADDTOHISTORYANDCACHE);
        }
        Firefox firefox = new Firefox();
        firefox.GetHistory(display:false);
        foreach (URL url in firefox.URLs)
        {
            MessageBox.Show(url.url);

            urlHistory.AddHistoryEntry(url.url, url.title, ADDURL_FLAG.ADDURL_ADDTOHISTORYANDCACHE);
        }

这是我的错误：

** * **异常文本** * **** System.Runtime.InteropServices.COMException (0x80070008)：没有足够的存储空间来处理此命令。（HRESULT 异常：0x80070008）在 UrlHistoryLibrary.UrlHistoryWrapperClass.AddHistoryEntry（String pocsUrl，String pocsTitle，ADDURL_FLAG dwIE（String pocsUrl，String pocsTitle，ADDURL_FLAG dwFlags）在 Namespace.IE）中的 UrlHistoryLibrary.IUrlHistoryStg2.AddUrl（String pocsUrl，String pocsTitle，ADDURL_FLAG dwFlags）。 \Users\Chris\documents\visual studio 2010\Projects\TestURLGUI4\TestURLGUI4\URLHistory.cs:C:\Users\Chris\documents\visual studio 2010\Projects\TestURLGUI4\TestURLGUI4 中 Namespace.Program.SyncAll() 的第 270 行\URLHistory.cs：TestURLGUI2.Form1.button11_Click(Object sender, EventArgs e) 中的第 152 行：\Users\Chris\documents\visual studio 2010\Projects\TestURLGUI4\TestURLGUI4\Form1.cs：System.Windows 中的第 247 行.

Edit:

Here is my new code:

    for (var i = 0; i < firefox.URLs.Count; i++ )
    {
        URL url = firefox.URLs[i];
        urlHistory.AddHistoryEntry(url.url, url.title, ADDURL_FLAG.ADDURL_ADDTOHISTORYANDCACHE);
        Thread.Sleep(3);
        form.label1.Text = i + "/" + firefox.URLs.Count;
      //  MessageBox.Show(url.url);
        Application.DoEvents();
    }

Now, with this code, I can go up to 8447 without getting this error, but then it gets thrown.

I had someone else try to do this, and this is what he said:

Just tried your code and and it seems that there is a limit on the number of the url records that can be added. I did the following steps.

  1. In Internet Explorer, Clear the history of websites I've visited.
  2. I tried your code.
  3. Got a COMException (0x80070008): Not enough storage is available to process this command. The exception is thrown at record number 41021 for me (Windows 7, 64bit).
  4. I tried your code again, and Got a very same exception. This time, No record have be added. To add the url records again. I have to clear the history of websites in Internet Explorer. I could not find a way to fix the problem.

For anyone who needs to know, the source code for the URLhistoryWrapper can be found on this CodeProject project.

Here is the solution I found to work. U need to run the

foreach (URL url in firefox.URLs)
    {
        MessageBox.Show(url.url);

        urlHistory.AddHistoryEntry(url.url, url.title, ADDURL_FLAG.ADDURL_ADDTOHISTORYANDCACHE);
    }

and the chrome ones, etc, in another thread. Like this:

Thread testthread = new Thread(SynceFirefoxToIE);
        testthread.Name = "FirefoxToIESynceThread";
        testthread.Start();


    }

    public void SynceFirefoxToIE() 
    {
        foreach (URL url in firefox.URLs)
      {

         urlHistory.AddHistoryEntry(url.url, url.title, ADDURL_FLAG.ADDURL_ADDTOHISTORYANDCACHE);
      }

    }
