问题描述

我做了,我想创建一个安装文件,Windows服务应用程序。通过我们的网站的网址当用户请求的应用程序与查询参数(例如:)我需要改变当前的app.config键值的查询参数值。

I made a windows service application that I want to create a setup file. When User request application via our website url with query parameters, (Eg: http://test.com/setup.exe?id=1212) I need to change the current app.config key value to that query parameter value.

我还需要在新版本已经准备好自动更新这个应用程序。所以的ClickOnce和松鼠的Windows可能是一种选择,而是因为我找不到方法来实现上述任务。

I also need to update this application automatically when new release is ready. So ClickOnce or squirrel for windows might be an option but as I couldn't find way to achieve above task.

下面的问题是有点类似,但不解决这个问题:

Following questions are bit similar but don't solve this problem:* How can we retreive query string information in a ClickOnce Application?* ClickOnce: How do I pass a querystring value to my app *through the installer*?

?我怎样才能做到这一点?

How can I achieve this?

推荐答案

1。首先,使查询字符串参数被传递给应用程序。

2。访问查询字符串这样

private NameValueCollection GetQueryString()
{
    if (ApplicationDeployment.IsNetworkDeployed)
    {
        try
        {
            string rawQueryString = String.Empty;
            rawQueryString = ApplicationDeployment.CurrentDeployment.ActivationUri.Query;
            NameValueCollection queryString;
            try
            {
                queryString = HttpUtility.ParseQueryString(ApplicationDeployment.CurrentDeployment.ActivationUri.Query);
            }
            catch (Exception ex)
            {
                throw new Exception("Unauthorized access!");
            }
            return queryString;
        }
        catch (Exception ex)
        {
            if (ApplicationDeployment.CurrentDeployment == null)
            {
                throw new Exception("Deployment error");
            }
            else if (ApplicationDeployment.CurrentDeployment.ActivationUri == null)
            {
                throw new Exception("Unable to read data");
            }
            else
            {
                throw new Exception("Error with deployment: " + ex.Message);
            }
        }
    }
    else
    {
        throw new Exception("This application may not be accessed directly");
    }
}



3。更新的app.config
