ViewStateException.Path Property
Gets the path of the HTTP request that resulted in a view-state exception.
Assembly: System.Web (in System.Web.dll)
This property returns the same value as the PATH_INFO variable in the ServerVariables property. It returns the portion of the path after the host name. For example, in the URL http://www.contoso.com/virdir/page.html, Path would return /virdir/page.html.
The following code example demonstrates how to implement a method that deserializes a base64-encoded string and returns an ICollection collection of property settings. The Deserialize method can throw an HttpException exception that contains a ViewStateException object as an inner exception. The example shows how you can catch an HttpException exception and retrieve the properties from the ViewStateException object.
Private Function LoadControlProperties(ByVal serializedProperties As String) As ICollection Dim controlProperties As ICollection = Nothing ' Create an ObjectStateFormatter to deserialize the properties. Dim formatter As New ObjectStateFormatter() Try ' Call the Deserialize method. controlProperties = CType(formatter.Deserialize(serializedProperties), ArrayList) Catch e As HttpException Dim vse As ViewStateException Dim logMessage As String vse = e.InnerException logMessage = "ViewStateException. Path: " + vse.Path + Environment.NewLine logMessage += "PersistedState: " + vse.PersistedState + Environment.NewLine logMessage += "Referer: " + vse.Referer + Environment.NewLine logMessage += "UserAgent: " + vse.UserAgent + Environment.NewLine LogEvent(logMessage) If (vse.IsConnected) Then HttpContext.Current.Response.Redirect("ErrorPage.aspx") Else Throw e End If End Try Return controlProperties End Function 'LoadControlProperties
