Removing (Deleting) Querystring in ASP.NET

We cannot delete a query string directly like below:


If you do this, you will get an error - collection is read-only. So, we need to write the below code before deleting the query string.

In C#:

PropertyInfo isreadonly = 
  "IsReadOnly", BindingFlags.Instance | BindingFlags.NonPublic);
// make collection editable
isreadonly.SetValue(this.Request.QueryString, false, null);
// remove


Dim isreadonly As PropertyInfo = _
  "IsReadOnly", BindingFlags.Instance Or BindingFlags.NonPublic)
' make collection editable
isreadonly.SetValue(Me.Request.QueryString, False, Nothing)
' remove
I hope that this will help you guys.
