Storing Orders into Site using streamWriter Class in c# getting Error

Question

Hi,
    I am using streamWriter class to write orders into text file.It's working.,But not my client asking to change site URL to store orders into that site.
I need to save orders into below path:
https://SP2010.org/Departments/Community/Communications/DocForms/Forms/Simple%20View.aspx
Getting Error: 
The given path's format is not supported.
In web.config File:
<AppSettings>
<add key="OrdersList" value="https://SP2010.org/Departments/Community/Communications/DocForms/Forms/Simple%20View.aspx"/>
</AppSettings>
Under Button control,wrote below code:
 string Orderslist = System.Configuration.ConfigurationManager.AppSettings["OrdersList"].ToString();
                        string fileName = Orderslist;
                        string fileText = fileName + nextorder.ToString();
                        //Check if file already exists. If yes, delete it. 
                        if (File.Exists(fileText))
                            File.Delete(fileText);
                        // Create a new file 
                        using (StreamWriter streamWriter = new StreamWriter(fileText))
                        {streamWriter.WriteLine(listItem["Title"]);
                                streamWriter.WriteLine(listItem["OrderDate"]);
                                streamWriter.WriteLine(listItem["OrderCreatedBy"]);
Thanks in Advance:
