c# - ClickOnce 部署自动更新不起作用

Question

我正在使用 ClickOnce部署以检查更新:

1. 我已经完成了发布选项卡中的设置、发布 URL 和检查更新路径，并在应用程序启动前检查更新并离线和在线运行应用程序。
2. 如果从本地系统安装应用程序，我会得到更新，但如果我从服务器安装应用程序，则它不会检查更新。

下面是我用来检查更新的代码。我该如何解决这个问题？

private void InstallUpdateSyncWithInfo()
{
    UpdateCheckInfo info = null;
    if (ApplicationDeployment.IsNetworkDeployed)
    {
        ApplicationDeployment ad = ApplicationDeployment.CurrentDeployment;

        try
        {
            info = ad.CheckForDetailedUpdate();
        }
        catch (DeploymentDownloadException dde)
        {
            MessageBox.Show("The new version of the application cannot be downloaded at this time. \n\nPlease check your network connection, or try again later. Error: " + dde.Message);
            return;
        }
        catch (InvalidDeploymentException ide)
        {
            MessageBox.Show("Cannot check for a new version of the application. The ClickOnce deployment is corrupt. Please redeploy the application and try again. Error: " + ide.Message);
            return;
        }
        catch (InvalidOperationException ioe)
        {
            MessageBox.Show("This application cannot be updated. It is likely not a ClickOnce application. Error: " + ioe.Message);
            return;
        }

        if (info.UpdateAvailable)
        {
            Boolean doUpdate = true;

            if (!info.IsUpdateRequired)
            {
                DialogResult dr = MessageBox.Show("An update is available. Would you like to update the application now?", "Update Available", MessageBoxButtons.OKCancel);
                if (!(DialogResult.OK == dr))
                {
                    doUpdate = false;
                }
            }
            else
            {
                // Display a message that the app MUST reboot. Display the minimum required version.
                MessageBox.Show("This application has detected a mandatory update from your current " +
                    "version to version " + info.MinimumRequiredVersion.ToString() +
                    ". The application will now install the update and restart.",
                    "Update Available", MessageBoxButtons.OK,
                    MessageBoxIcon.Information);
            }

            if (doUpdate)
            {
                try
                {
                    ad.Update();
                    MessageBox.Show("The application has been upgraded, and will now restart.");
                    Application.Restart();

                }
                catch (DeploymentDownloadException dde)
                {
                    MessageBox.Show("Cannot install the latest version of the application. \n\nPlease check your network connection, or try again later. Error: " + dde);
                    return;
                }
            }
        }
    }
    else
    {
        MessageBox.Show("There are no updates available");
    }
}

Answer 1

安装/更新位置应该是文件夹，而不是 igofed 提到的 test.html 文件。

接下来的内容不会回答您的问题，但希望对您有用。 .NET 中存在错误您在示例中调用的 ad.CheckForDetailedUpdate() 方法中的框架，因为如果调用次数足够多(在自主应用程序无限期运行的情况下)，它将启动抛出 COMException 和 InvalidOperationException

类型的异常

现在不幸的是，我不记得我是在哪里发现这个错误的，所以我无法给出它应得的信用，但我们通过检查 list 文件中的版本号并将其与当前版本进行比较解决了这个问题汇编版本。

private bool CheckForUpdateAvailable()
{
    Uri updateLocation = ApplicationDeployment.CurrentDeployment.UpdateLocation;

    //Used to use the Clickonce API but we've uncovered a pretty serious bug which results in a COMException and the loss of ability
    //to check for updates. So until this is fixed, we're resorting to a very lo-fi way of checking for an update.

    WebClient webClient = new WebClient();
    webClient.Encoding = Encoding.UTF8;
    string manifestFile = webClient.DownloadString(updateLocation);

    //We have some garbage info from the file header, presumably because the file is a .application and not .xml
    //Just start from the start of the first tag
    int startOfXml = manifestFile.IndexOfAny(new[] { '<' });
    manifestFile = manifestFile.Substring(startOfXml);

    Version version;

    XmlDocument doc = new XmlDocument();

    //build the xml from the manifest
    doc.LoadXml(manifestFile);

    XmlNodeList nodesList = doc.GetElementsByTagName("assemblyIdentity");
    if (nodesList == null || nodesList.Count <= 0)
    {
        throw new XmlException("Could not read the xml manifest file, which is required to check if an update is available.");
    }

    XmlNode theNode = nodesList[0];
    version = new Version(theNode.Attributes["version"].Value);

    if (version > ApplicationDeployment.CurrentDeployment.CurrentVersion)
    {
        // update application
        return true;
    }
    return false;
}

您的更新检查调用代码...

if (ApplicationDeployment.IsNetworkDeployed)
{
    bool updateIsAvailable;

    try
    {
        updateIsAvailable = CheckForUpdateAvailable();
    }
    catch
    {
        //not network deployed etc...
    }

    if (updateIsAvailable)
    {
        ad = ApplicationDeployment.CurrentDeployment;

        if (ad == null)
        {
            return;
        }

        ad.Update();
        Application.Restart();
    }
}
