ApplicationDeployment.ActivationUri Property

Gets the URL used to launch the deployment manifest of the application.

Namespace:  System.Deployment.Application
Assembly:  System.Deployment (in System.Deployment.dll)

public Uri ActivationUri { get; }

Property Value

Type: System.Uri
A zero-length string if the TrustUrlParameters property in the deployment manifest is false, or if the user has supplied a UNC to open the deployment or has opened it locally. Otherwise, the return value is the full URL used to launch the application, including any parameters.

This property will work in both fully trusted and partially trusted applications.

The following code shows how to retrieve the URL parameters by using ActivationUri, and how to use the HttpUtility class to parse the query string safely. Multiple occurrences of the same query string variable are consolidated in one entry of the returned NameValueCollection.

private NameValueCollection GetQueryStringParameters()
    NameValueCollection nameValueTable = new NameValueCollection();

    if (ApplicationDeployment.IsNetworkDeployed)
        string queryString = ApplicationDeployment.CurrentDeployment.ActivationUri.Query;
        nameValueTable = HttpUtility.ParseQueryString(queryString);

    return (nameValueTable);
